Ninad Palsule ca03310737 hw/fsi: Introduce IBM's FSI master
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

This commit models the FSI master. CFAM is hanging out of FSI master which is a bus controller.

The FSI master: A controller in the platform service processor (e.g.
BMC) driving CFAM engine accesses into the POWER chip. At the
hardware level FSI is a bit-based protocol supporting synchronous and
DMA-driven accesses of engines in a CFAM.

Ninad Palsule f32f8e4d20 hw/fsi: Introduce IBM's cfam
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

The Common FRU Access Macro (CFAM), an address space containing
various "engines" that drive accesses on busses internal and external
to the POWER chip. Examples include the SBEFIFO and I2C masters. The
engines hang off of an internal Local Bus (LBUS) which is described
by the CFAM configuration block.

Ninad Palsule 6a2897bb5f hw/fsi: Introduce IBM's fsi-slave model
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

The FSI slave: The slave is the terminal point of the FSI bus for
FSI symbols addressed to it. Slaves can be cascaded off of one
another. The slave's configuration registers appear in address space
of the CFAM to which it is attached.

Ninad Palsule ca782334cb hw/fsi: Introduce IBM's scratchpad device
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

The scratchpad provides a set of non-functional registers. The firmware
is free to use them, hardware does not support any special management
support. The scratchpad registers can be read or written from LBUS
slave. The scratch pad is managed under FSI CFAM state.

Philippe Mathieu-Daudé dc13909ed0 hw/arm/aspeed: Check for CPU types in machine_run_board_init()
Aspeed SoCs use a single CPU type (set as AspeedSoCClass::cpu_type).
Convert it to a NULL-terminated array (of a single non-NULL element).

Set MachineClass::valid_cpu_types[] to use the common machine code
to provide hints when the requested CPU is invalid (see commit
e702cbc19e ("machine: Improve is_cpu_type_supported()").

Peter Maydell 18281b2578 bswap.h: Fix const_le64() macro
The const_le64() macro introduced in commit 845d80a8c7 turns out
to have a bug which means that on big-endian systems the compiler
complains if the argument isn't already a 64-bit type. This hasn't
caused a problem yet, because there are no in-tree uses, but it
means it's not possible for anybody to add one without it failing CI.

This example is from an attempted use of it with the argument '0',
from the s390 CI runner's gcc:

../block/blklogwrites.c: In function ‘blk_log_writes_co_do_log’:
../include/qemu/bswap.h:148:36: error: left shift count >= width of
type [-Werror=shift-count-overflow]
148 | ((((_x) & 0x00000000000000ffU) << 56) | \
| ^~
../block/blklogwrites.c:409:27: note: in expansion of macro ‘const_le64’
409 | .nr_entries = const_le64(0),
| ^~~~~~~~~~
../include/qemu/bswap.h:149:36: error: left shift count >= width of
type [-Werror=shift-count-overflow]
149 | (((_x) & 0x000000000000ff00U) << 40) | \
| ^~
../block/blklogwrites.c:409:27: note: in expansion of macro ‘const_le64’
409 | .nr_entries = const_le64(0),
| ^~~~~~~~~~
cc1: all warnings being treated as errors

Fix this by making all the constants in the macro have the ULL
suffix.  This will cause them all to be 64-bit integers, which means
the result of the logical & will also be an unsigned 64-bit type,
even if the input to the macro is a smaller type, and so the shifts
will be in range.

Rayhan Faizel 988f244297 hw/char/imx_serial: Implement receive FIFO and ageing timer
This patch implements a 32 half word FIFO as per imx serial device
specifications.  If a non empty FIFO is below the trigger level, an
ageing timer will tick for a duration of 8 characters.  On expiry,
AGTIM will be set triggering an interrupt.  AGTIM timer resets when
there is activity in the receive FIFO.

Otherwise, RRDY is set when trigger level is exceeded.  The receive
trigger level is 8 in newer kernel versions and 1 in older ones.

This change will break migration compatibility for the imx boards.

Guenter Roeck b0d1021ed9 fsl-imx6ul: Add various missing unimplemented devices
Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.

This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.

Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation
thus no longer covered the various unimplemented devices in the affected
address range.

Stefan Hajnoczi 3bcc17f065 virtio-blk: move dataplane code into virtio-blk.c
The dataplane code used to be significantly different from the
non-dataplane code and therefore had a separate source file.

Over time the difference has gotten smaller because the I/O code paths
were unified. Nowadays the distinction between the VirtIOBlock and
VirtIOBlockDataPlane structs is more of an inconvenience that hinders
code simplification.

Move hw/block/dataplane/virtio-blk.c into hw/block/virtio-blk.c, merging
VirtIOBlockDataPlane's fields into VirtIOBlock.

hw/block/virtio-blk.c used VirtIOBlock->dataplane to check if
virtio_blk_data_plane_create() was successful. This is not necessary
because ->dataplane_started and ->dataplane_disabled can be used
instead. This patch makes those changes in order to drop
VirtIOBlock->dataplane.

Peter Krempa 72098a3aba stream: Allow users to request only format driver names in backing file format
Introduce a new flag 'backing-mask-protocol' for the block-stream QMP
command which instructs the internals to use 'raw' instead of the
protocol driver in case when a image is used without a dummy 'raw'
wrapper.

The flag is designed such that it can be always asserted by management
tools even when there isn't any update to backing files.

The flag will be used by libvirt so that the backing images still
reference the proper format even when libvirt will stop using the dummy
raw driver (raw driver with no other config). Libvirt needs this so that
the images stay compatible with older libvirt versions which didn't
expect that a protocol driver name can appear in the backing file format
field.

Bin Meng 62570f1434 hw/elf_ops: Ignore loadable segments with zero size
Some ELF files really do have segments of zero size, e.g.:

Program Headers:
  Type           Offset             VirtAddr           PhysAddr
                 FileSiz            MemSiz              Flags  Align
  RISCV_ATTRIBUT 0x00000000000025b8 0x0000000000000000 0x0000000000000000
                 0x000000000000003e 0x0000000000000000  R      0x1
  LOAD           0x0000000000001000 0x0000000080200000 0x0000000080200000
                 0x00000000000001d1 0x00000000000001d1  R E    0x1000
  LOAD           0x00000000000011d1 0x00000000802001d1 0x00000000802001d1
                 0x0000000000000e37 0x0000000000000e37  RW     0x1000
  LOAD           0x0000000000000120 0x0000000000000000 0x0000000000000000
                 0x0000000000000000 0x0000000000000000         0x1000

The current logic does not check for this condition, resulting in
the incorrect assignment of 'lowaddr' as zero.

There is already a piece of codes inside the segment traversal loop
that checks for zero-sized loadable segments for not creating empty
ROM blobs. Let's move this check to the beginning of the loop to
cover both scenarios.
