On AST2600, I2C has a secondary mode, called "new mode", which changes
the layout of registers, adds some minor behavior changes, and
introduces a new way to transfer data called "packet mode".
Most of the bit positions of the fields are the same between old and new
mode, so we use SHARED_FIELD_XX macros to reuse most of the code between
the different modes.
For packet mode, most of the command behavior is the same compared to
other modes, but there are some minor changes to how interrupts are
handled compared to other modes.

Occasionally a peripheral will have different operating modes, where the
MMIO layout changes, but some of the register fields have the same offsets
and behaviors.
To help support this, we add SHARED_FIELD_XX macros that create SHIFT,
LENGTH, and MASK macros for the fields that are shared across registers,
and accessors for these fields.
An example use may look as follows:
There is a peripheral with registers REG_MODE1 and REG_MODE2 at
different addreses, and both have a field FIELD1 initialized by
SHARED_FIELD().
Depending on what mode the peripheral is operating in, the user could
extract FIELD1 via
SHARED_ARRAY_FIELD_EX32(s->regs, R_REG_MODE1, FIELD1)
or
SHARED_ARRAY_FIELD_EX32(s->regs, R_REG_MODE2, FIELD1)

The bug is an uninitialized memory read, along the translate_fail
path, which results in garbage being read from iotlb_to_section,
which can lead to a crash in io_readx/io_writex.
The bug may be fixed by writing any value with zero
in ~TARGET_PAGE_MASK, so that the call to iotlb_to_section using
the xlat'ed address returns io_mem_unassigned, as desired by the
translate_fail path.
It is most useful to record the original physical page address,
which will eventually be logged by memory_region_access_valid
when the access is rejected by unassigned_mem_accepts.

The 'resume_as_sreset' attribute of a cpu is set when a thread is
entering a stop state on ppc books. It causes the thread to be
re-routed to vector 0x100 when woken up by an exception. So it must be
cleared on reset or a thread might be re-routed unexpectedly after a
reset, when it was not in a stop state and/or when the appropriate
exception handler isn't set up yet.
Using skiboot, it can be tested by resetting the system when it is
quiet and most threads are idle and in stop state.
After the reset occurs, skiboot elects a primary thread and all the
others wait in secondary_wait. The primary thread does all the system
initialization from main_cpu_entry() and at some point, the
decrementer interrupt starts ticking. The exception vector for the
decrementer interrupt is in place, so that shouldn't be a
problem. However, if that primary thread was in stop state prior to
the reset, and because the resume_as_sreset parameters is still set,
it is re-routed to exception vector 0x100. Which, at that time, is
still defined as the entry point for BML. So that primary thread
restarts as new and ends up being treated like any other secondary
thread. All threads are now waiting in secondary_wait.
It results in a full system hang with no message on the console, as
the uart hasn't been init'ed yet. It's actually not obvious to realise
what's happening if not tracing reset (-d cpu_reset). The fix is
simply to clear the 'resume_as_sreset' attribute on reset.

Commit c29018cc73 added an env->fpscr OR operation using a ternary

However, in the current body of do_fpscr_check_status(), 'error' is
granted to be always non-zero at that point. The result is that Coverity
is less than pleased:
Control flow issues (DEADCODE)
Execution cannot reach the expression "0ULL" inside this statement:

When accessing a thread context through the IC BAR, the offset of the
page in the BAR identifies the CPU. From that offset, we can compute
the PIR (processor ID register) of the CPU to do the data structure
lookup. On P10, the current code assumes an access for node 0 when
computing the PIR. Everything is almost in place to allow access for
other nodes though. So this patch reworks how the PIR value is
computed so that we can access all thread contexts through the IC BAR.
The PIR is already correct on P9, so no need to modify anything there.

Recent changes to pcie_host corrected size of its internal region to
match what it expects: only the low 28 bits are ever decoded. Previous
code just ignored bit 29 (if size was 1 << 29) in the address which does
not make much sense. We are now asserting on size > 1 << 28 instead,
but PPC 4xx actually allows guest to configure different sizes, and some
firmwares seem to set it to 1 << 29.
This caused e.g. qemu-system-ppc -M sam460ex to exit with an assert when
the guest writes a value to CFGMSK register when trying to map config
space. This is done in the board firmware in ppc4xx_init_pcie_port() in
roms/u-boot-sam460ex/arch/powerpc/cpu/ppc4xx/4xx_pcie.c
It's not clear what the proper fix should be but for now let's force the
size to 256MB, so anything outside the expected address range is
ignored.
Fixes: commit 1f1a7b2269 ("include/hw/pci/pcie_host: Correct PCIE_MMCFG_SIZE_MAX")

At any step when any validation fail in check_erst_backend_storage(), there is
no need to continue further through other validation checks. Further, by
continuing even when record_size is 0, we run the risk of triggering a divide
by zero error if we continued with other validation checks. Hence, we should
simply return from this function upon validation failure.
