b76624de50 esp: remove minlen restriction in handle_ti
The limiting of DMA transfers to the maximum size of the available data is already
handled by esp_do_dma() and do_dma_pdma_cb().

6cc88d6bf9 esp: remove dma_left from ESPState
The ESP device already keeps track of the remaining bytes left to transfer via
its TC (transfer counter) register which is decremented for each byte that
is transferred across the SCSI bus.

Switch the transfer logic to use the value of TC instead of dma_left and then
remove dma_left completely, adding logic to the vmstate_esp post_load() function
to transfer the old dma_left value to the TC register during migration from
older versions.

5eb7a23fb2 esp: remove dma_counter from ESPState
The value of dma_counter is set once at the start of the transfer and remains
the same until the transfer is complete. This allows the check in esp_transfer_data
to be simplified since dma_left will always be non-zero until the transfer is
completed.

96676c2f74 esp: apply transfer length adjustment when STC is zero at TC load time
Perform the length adjustment whereby a value of 0 in the STC represents
a transfer length of 0x10000 at the point where the TC is loaded at the
start of a DMA command rather than just when a TI (Transfer Information)
command is executed. This better matches the description as given in the
datasheet.

0bd005be78 esp: add vmstate_esp version to embedded ESPState
The QOM object representing ESPState is currently embedded within both the
SYSBUS_ESP and PCI_ESP devices with migration state handled by embedding
vmstate_esp within each device using VMSTATE_STRUCT.

Since the vmstate_esp fields are embedded directly within the migration
stream, the incoming vmstate_esp version_id is lost. The only version information
available is that from vmstate_sysbus_esp_scsi and vmstate_esp_pci_scsi, but
those versions represent their respective devices and not that of the underlying
ESPState.

Resolve this by adding a new version-dependent field in vmstate_sysbus_esp_scsi
and vmstate_esp_pci_scsi which stores the vmstate_esp version_id field within
ESPState to be used to allow migration from older QEMU versions.

Finally bump the vmstate_esp version to 5 to cover the upcoming ESPState changes
within this patch series.

707b45a247 tcg/aarch64: Fix constant subtraction in tcg_out_addsub2
An hppa guest executing

0x000000000000e05c:  ldil L%10000,r4
0x000000000000e060:  ldo 0(r4),r4
0x000000000000e064:  sub r3,r4,sp

produces

 ---- 000000000000e064 000000000000e068
 sub2_i32 tmp0,tmp4,r3,$0x1,$0x10000,$0x0

after folding and constant propagation.  Then we hit

tcg-target.c.inc:640: tcg_out_insn_3401: Assertion `aimm <= 0xfff' failed.

because aimm is in fact -16, but unsigned.

The ((bl < 0) ^ sub) condition which negates bl is incorrect and will
always lead to this abort.  If the constant is positive, sub will make
it negative; if the constant is negative, sub will keep it negative.

ef95ca0382 hw/sh4/sh7750_regs: Replace link to license by its full content
This file is borrowed from the RTEMS source code, which comes
with a GPL-2.0-or-later license with a header exception.

Expand the GPL-2.0-or-later license in place to not be dependent
on a 3rd party website. This also fix the misleading comment "The
license and distribution terms for this file may be found in the
file LICENSE in this distribution" referring to the RTEMS distribution
and not to the QEMU one.

c64bd101fe hw/pci-host: Introduce SH_PCI Kconfig entry
We want to be able to use the 'SH4' config for architecture
specific features. Add more fine-grained selection by adding
a CONFIG_SH_PCI selector for the SH4 PCI controller.
Move the file with the other PCI host devices in hw/pci-host
and add its missing MAINTAINERS entries.

Add more fine-grained selection by adding a CONFIG_TC58128
selector for the TC58128 eeprom.

As this device is only used by the Shix machine, add an entry
to the proper section in MAINTAINERS.
