According to the datasheet of ASPEED SOCs,
each I2C bus has their own pool buffer since AST2500.
Only AST2400 utilized a pool buffer share to all I2C bus.
And firmware required to set the offset of pool buffer
by writing "Function Control Register(I2CD 00)"
To make this model more readable, will change to introduce
a new bus pool buffer attribute in AspeedI2Cbus.
So, it does not need to calculate the pool buffer offset
for different I2C bus.
This patch rename the I2C class pool attribute to share_pool.
It make user more understand share pool and bus pool
are different.
Incrementing the version of aspeed_i2c_vmstate to 3.

SMMUv3 OAS is currently hardcoded in the code to 44 bits, for nested
configurations that can be a problem, as stage-2 might be shared with
the CPU which might have different PARANGE, and according to SMMU manual
ARM IHI 0070F.b:
6.3.6 SMMU_IDR5, OAS must match the system physical address size.
This patch doesn't change the SMMU OAS, but refactors the code to
make it easier to do that:
- Rely everywhere on IDR5 for reading OAS instead of using the
SMMU_IDR5_OAS macro, so, it is easier just to change IDR5 and
it propagages correctly.
- Add additional checks when OAS is greater than 48bits.
- Remove unused functions/macros: pa_range/MAX_PA.

When nested translation is requested, do the following:
- Translate stage-1 table address IPA into PA through stage-2.
- Translate stage-1 table walk output (IPA) through stage-2.
- Create a single TLB entry from stage-1 and stage-2 translations
using logic introduced before.
smmu_ptw() has a new argument SMMUState which include the TLB as
stage-1 table address can be cached in there.
Also in smmu_ptw(), a separate path used for nesting to simplify the
code, although some logic can be combined.
With nested translation class of translation fault can be different,
from the class of the translation, as faults from translating stage-1
tables are considered as CLASS_TT and not CLASS_IN, a new member
"is_ipa_descriptor" added to "SMMUPTWEventInfo" to differ faults
from walking stage 1 translation table and faults from translating

This patch adds support for nested (combined) TLB entries.
The main function combine_tlb() is not used here but in the next
patches, but to simplify the patches it is introduced first.
Main changes:
1) New field added in the SMMUTLBEntry struct: parent_perm, for
nested TLB, holds the stage-2 permission, this can be used to know
the origin of a permission fault from a cached entry as caching
the “and” of the permissions loses this information.
SMMUPTWEventInfo is used to hold information about PTW faults so
the event can be populated, the value of stage used to be set
based on the current stage for TLB permission faults, however
with the parent_perm, it is now set based on which perm has
the missing permission
When nesting is not enabled it has the same value as perm which
doesn't change the logic.
2) As combined TLB implementation is used, the combination logic
chooses:
- tg and level from the entry which has the smallest addr_mask.
- Based on that the iova that would be cached is recalculated.
- Translated_addr is chosen from stage-2.

In the next patch, combine_tlb() will be added which combines 2 TLB
entries into one for nested translations, which chooses the granule
and level from the smallest entry.
This means that with nested translation, an entry can be cached with
the granule of stage-2 and not stage-1.
However, currently, the lookup for an IOVA is done with input stage
granule, which is stage-1 for nested configuration, which will not
work with the above logic.
This patch reworks lookup in that case, so it falls back to stage-2
granule if no entry is found using stage-1 granule.
Also, drop aligning the iova to avoid over-aligning in case the iova
is cached with a smaller granule, the TLB lookup will align the iova
anyway for each granule and level, and the page table walker doesn't
consider the page offset bits.

According to ARM SMMU architecture specification (ARM IHI 0070 F.b),
In "5.2 Stream Table Entry":
[51:6] S1ContextPtr
If Config[1] == 1 (stage 2 enabled), this pointer is an IPA translated by
stage 2 and the programmed value must be within the range of the IAS.
In "5.4.1 CD notes":
The translation table walks performed from TTB0 or TTB1 are always performed
in IPA space if stage 2 translations are enabled.
This patch implements translation of the S1 context descriptor pointer and
TTBx base addresses through the S2 stage (IPA -> PA)
smmuv3_do_translate() is updated to have one arg which is translation
class, this is useful to:
- Decide wether a translation is stage-2 only or use the STE config.
- Populate the class in case of faults, WALK_EABT is left unchanged
for stage-1 as it is always IN, while stage-2 would match the
used class (TT, IN, CD), this will change slightly when the ptw
supports nested translation as it can also issue TT event with
class IN.
In case for stage-2 only translation, used in the context of nested
translation, the stage and asid are saved and restored before and
after calling smmu_translate().
Translating CD or TTBx can fail for the following reasons:
1) Large address size: This is described in
(3.4.3 Address sizes of SMMU-originated accesses)
- For CD ptr larger than IAS, for SMMUv3.1, it can trigger either
C_BAD_STE or Translation fault, we implement the latter as it
requires no extra code.
- For TTBx, if larger than the effective stage 1 output address size, it
triggers C_BAD_CD.
2) Faults from PTWs (7.3 Event records)
- F_ADDR_SIZE: large address size after first level causes stage 2 Address
Size fault (Also in 3.4.3 Address sizes of SMMU-originated accesses)
- F_PERMISSION: Same as an address translation. However, when
CLASS == CD, the access is implicitly Data and a read.
- F_ACCESS: Same as an address translation.
- F_TRANSLATION: Same as an address translation.
- F_WALK_EABT: Same as an address translation.
These are already implemented in the PTW logic, so no extra handling
required.
As in CD and TTBx translation context, the iova is not known, setting
the InputAddr was removed from "smmuv3_do_translate" and set after
from "smmuv3_translate" with the new function "smmuv3_fixup_event"

ASID and VMID used to be uint16_t in the translation config, however,
in other contexts they can be int as -1 in case of TLB invalidation,
to represent all (don’t care).
When stage-2 was added asid was set to -1 in stage-2 and vmid to -1
in stage-1 configs. However, that meant they were set as (65536),
this was not an issue as nesting was not supported and no
commands/lookup uses both.
With nesting, it’s critical to get this right as translation must be
tagged correctly with ASID/VMID, and with ASID=-1 meaning stage-2.
Represent ASID/VMID everywhere as int.

smmuv3_translate() does everything from STE/CD parsing to TLB lookup
and PTW.
Soon, when nesting is supported, stage-1 data (tt, CD) needs to be
translated using stage-2.
Split smmuv3_translate() to 3 functions:
- smmu_translate(): in smmu-common.c, which does the TLB lookup, PTW,
TLB insertion, all the functions are already there, this just puts
them together.
This also simplifies the code as it consolidates event generation
in case of TLB lookup permission failure or in TT selection.
- smmuv3_do_translate(): in smmuv3.c, Calls smmu_translate() and does
the event population in case of errors.
- smmuv3_translate(), now calls smmuv3_do_translate() for
translation while the rest is the same.
Also, add stage in trace_smmuv3_translate_success()

Currently, translation stage is represented as an int, where 1 is stage-1 and
2 is stage-2, when nested is added, 3 would be confusing to represent nesting,
so we use an enum instead.
While keeping the same values, this is useful for:
- Doing tricks with bit masks, where BIT(0) is stage-1 and BIT(1) is
stage-2 and both is nested.
- Tracing, as stage is printed as int.

The SMMUv3 spec (ARM IHI 0070 F.b - 7.3 Event records) defines the
class of events faults as:
CLASS: The class of the operation that caused the fault:
- 0b00: CD, CD fetch.
- 0b01: TTD, Stage 1 translation table fetch.
- 0b10: IN, Input address
However, this value was not set and left as 0 which means CD and not
IN (0b10).
Another problem was that stage-2 class is considered IN not TT for
EABT, according to the spec:
Translation of an IPA after successful stage 1 translation (or,
in stage 2-only configuration, an input IPA)
- S2 == 1 (stage 2), CLASS == IN (Input to stage)
This would change soon when nested translations are supported.
While at it, add an enum for class as it would be used for nesting.
However, at the moment stage-1 and stage-2 use the same class values,
except for EABT.

For the following events (ARM IHI 0070 F.b - 7.3 Event records):
- F_TRANSLATION
- F_ACCESS
- F_PERMISSION
- F_ADDR_SIZE
If fault occurs at stage 2, S2 == 1 and:
- If translating an IPA for a transaction (whether by input to
stage 2-only configuration, or after successful stage 1 translation),
CLASS == IN, and IPA is provided.
At the moment only CLASS == IN is used which indicates input
translation.
However, this was not implemented correctly, as for stage 2, the code
only sets the S2 bit but not the IPA.
This field has the same bits as FetchAddr in F_WALK_EABT which is
populated correctly, so we don’t change that.
The setting of this field should be done from the walker as the IPA address
wouldn't be known in case of nesting.
For stage 1, the spec says:
If fault occurs at stage 1, S2 == 0 and:
CLASS == IN, IPA is UNKNOWN.
So, no need to set it to for stage 1, as ptw_info is initialised by zero in
smmuv3_translate().

According to the SMMU architecture specification (ARM IHI 0070 F.b),
in “3.4 Address sizes”
The address output from the translation causes a stage 1 Address Size
fault if it exceeds the range of the effective IPA size for the given CD.
However, this check was missing.
There is already a similar check for stage-2 against effective PA.

It is common practice when implementing double-buffering on VideoCore
to do so by multiplying the height of the virtual buffer by the
number of virtual screens desired (i.e., two - in the case of
double-bufferring).
At present, this won't work in QEMU because the logic in
fb_use_offsets require that both the virtual width and height exceed
their physical counterparts.
This appears to be unintentional/a typo and indeed the comment
states; "Experimentally, the hardware seems to do this only if the
viewport size is larger than the physical screen". The
viewport/virtual size would be larger than the physical size if
either virtual dimension were larger than their physical counterparts
and not necessarily both.

Commit b1f1e9dcfa renamed 'riscv,delegate' to 'riscv,delegation' since
it is the correct name as per dt-bindings, and the absence of the
correct name will result in validation fails when dumping the dtb and
using dt-validate.
But this change has a side-effect: every other firmware available that
is AIA capable is using 'riscv,delegate', and it will fault/misbehave if
this property isn't present. The property was added back in QEMU 7.0,
meaning we have 2 years of firmware development using the wrong
property.
Re-introducing 'riscv,delegate' while keeping 'riscv,delegation' allows
older firmwares to keep booting with the 'virt' machine.
'riscv,delegate' is then marked for future deprecation with its use
being discouraged from now on.

switch operation in mmc cards, updated the ext_csd register to
request changes in card operations. Here we implement similar
sequence but requests are mostly dummy and make no change.
Implement SWITCH_ERROR if the write operation offset goes beyond
length of ext_csd.

Avoid hardcoding 1MiB boot size in EXT_CSD_BOOT_MULT,
expose it as 'boot-partition-size' QOM property.
By default, do not use any size. The board is responsible
to set the boot partition size property.

The parameters mimick a real 4GB eMMC, but it can be set to various
sizes.

EXT_CSD values from Vincent's patch simplivied for Spec v4.3:
- Remove deprecated keys:
. EXT_CSD_SEC_ERASE_MULT
. EXT_CSD_SEC_TRIM_MULT
- Set some keys to not defined / implemented:
. EXT_CSD_HPI_FEATURES
. EXT_CSD_BKOPS_SUPPORT
. EXT_CSD_SEC_FEATURE_SUPPORT
. EXT_CSD_ERASE_TIMEOUT_MULT
. EXT_CSD_PART_SWITCH_TIME
. EXT_CSD_OUT_OF_INTERRUPT_TIME
- Simplify:
. EXT_CSD_ACC_SIZE (6 -> 1)
16KB of super_page_size -> 512B (BDRV_SECTOR_SIZE)
. EXT_CSD_HC_ERASE_GRP_SIZE (4 -> 1)
. EXT_CSD_HC_WP_GRP_SIZE (4 -> 1)
. EXT_CSD_S_C_VCC[Q] (8 -> 1)
. EXT_CSD_S_A_TIMEOUT (17 -> 1)
. EXT_CSD_CARD_TYPE (7 -> 3)
Dual data rate -> High-Speed mode
- Update:
. EXT_CSD_CARD_TYPE (7 -> 3)
High-Speed MultiMediaCard @ 26MHz & 52MHz
. Performances (0xa -> 0x46)
Class B at 3MB/s. -> Class J at 21MB/s
. EXT_CSD_REV (5 -> 3)
Rev 1.5 (spec v4.41) -> Rev 1.3 (spec v4.3)
- Use load/store API to set EXT_CSD_SEC_CNT
- Remove R/W keys, normally zeroed at reset
. EXT_CSD_BOOT_INFO
Migrate the Modes segment (192 lower bytes) but not the
full EXT_CSD register, see Spec v4.3, chapter 8.4
"Extended CSD register":
The Extended CSD register defines the card properties
and selected modes. It is 512 bytes long. The most
significant 320 bytes are the Properties segment, which
defines the card capabilities and cannot be modified by
the host. The lower 192 bytes are the Modes segment,
which defines the configuration the card is working in.
These modes can be changed by the host by means of the
SWITCH command.

The JEDEC standards specifies a sleep state where the eMMC won't
answer any command appart from RESET and WAKEUP and go to low power
state. Implement this state and the corresponding command number 5.
