hw/i2c/aspeed: Fix wrong I2CC_DMA_LEN when I2CM_DMA_TX/RX_ADDR set first
In the previous design, the I2C model would update I2CC_DMA_LEN (0x54) based on
the value of I2CM_DMA_LEN (0x1C) when the firmware set either I2CM_DMA_TX_ADDR
(0x30) or I2CM_DMA_RX_ADDR (0x34). However, this only worked correctly if the
firmware set I2CM_DMA_LEN before setting I2CM_DMA_TX_ADDR or I2CM_DMA_RX_ADDR.
If the firmware instead set I2CM_DMA_TX_ADDR or I2CM_DMA_RX_ADDR before setting
I2CM_DMA_LEN, the value written to I2CC_DMA_LEN would be incorrect.
To fix this issue, the model should be updated to set I2CC_DMA_LEN when the
firmware writes to the I2CM_DMA_LEN register, rather than when it writes to the
I2CM_DMA_RX_ADDR and I2CM_DMA_TX_ADDR registers.

Hexagon (target/hexagon) analyze all reads before writes
I noticed that analyze_packet is marking the implicit pred reads after
marking all the writes. However, the semantics of the instrucion and
packet are to do all the reads, then do the operation, then do all the
writes.
Here is the old code
static void analyze_packet(DisasContext *ctx)
{
Packet *pkt = ctx->pkt;
ctx->read_after_write = false;
ctx->has_hvx_overlap = false;
for (int i = 0; i < pkt->num_insns; i++) {
Insn *insn = &pkt->insn[i];
ctx->insn = insn;
if (opcode_analyze[insn->opcode]) {
opcode_analyze[insn->opcode](ctx);
}
mark_implicit_reg_writes(ctx);
mark_implicit_pred_writes(ctx);
mark_implicit_pred_reads(ctx);
}
ctx->need_commit = need_commit(ctx);
}
Recall that opcode_analyze[insn->opcode](ctx) will mark all the
explicit reads then all the explicit writes.
To properly handle the semantics, we'll create two new functions
mark_implicit_reads
mark_implicit_writes
Then we change gen_analyze_funcs.py to add a call to the former
after all the explicit reads and a call to the latter after all
the explicit_writes.
The reason this is an RFC patch is I can't find any instructions
where this distinction makes a difference in ctx->need_commit which
determines if the packet commit can be short-circuited. However, this
could change in the future if the architecture introduces an
instruction with an implicit read of a register that is also written
(either implicit or explicit). Then, anlayze_packet would detect
a read-after-write, and the packet would not short-circuit. The
execution would be correct, but the performance would not be optimal.

qga/vss-win32: Fix ConvertStringToBSTR redefinition with newer MinGW
Newer versions of MinGW-w64 provide ConvertStringToBSTR() in the
_com_util namespace via <comutil.h>. This causes a redefinition
error when building qemu-ga on Windows with these toolchains.
Add a meson check to detect whether ConvertStringToBSTR is already
available, and conditionally compile our fallback implementation
only when the system does not provide one.

system/memory: Allow restricting legacy ldst_phys() API usage
Commit 500131154d6 ("exec.c: Add new address_space_ld*/st*
functions") added a new API to fix a shortcoming of the
ld/st*_phys() API, which does blind bus access, not reporting
failure (and it also allow to provide transaction attributes).
Later commit 42874d3a8c6 ("Switch non-CPU callers from ld/st*_phys
to address_space_ld/st*") automatically converted the legacy uses
to the new API, not precising transaction attributes
(MEMTXATTRS_UNSPECIFIED) and ignoring the transation result (passing
NULL pointer as MemTxResult).
While this is a faithful replacement, without any logical change,
we later realized better is to not use MEMTXATTRS_UNSPECIFIED or
NULL MemTxResult, and adapt each call site on a pair basis, looking
at the device model datasheet to do the correct behavior (which is
unlikely to ignore transaction failures).
Since this is quite some work, we defer that to device model
maintainers. Meanwhile we introduce a definition, to allow a
target which removed all legacy API call to prohibit further
legacy API uses, named "TARGET_NOT_USING_LEGACY_LDST_PHYS_API".
Since all targets should be able to check this definition, we
take care to not poison it.

system/memory: Remove address_space_stl_notdirty and stl_phys_notdirty
stl_phys_notdirty() was added in commit 8df1cd076cc ("physical memory

Meanwhile 20 years passed, we might never have understood / used it

hw/arm: Avoid address_space_stl_notdirty() when generating bootloader
When using the '-kernel' command line option, a bootloader is
emitted, calling address_space_stl_notdirty().
The _notdirty() variant is supposed to /not/ mark the updated
CODE page as dirty, to not re-translate it. However this code
is only used with the '-kernel' CLI option after the machine
is created and /before/ the vCPUs run, and *only* during the
first (cold) reset; not during following (hot) resets. The
optimisation is totally not justified, since we haven't
translated any guest code yet.
Replace by the normal address_space_stl() helper.

block: reduce files included by block/aio.h
Avoid including all of qdev everywhere (the hw/core/qdev.h header in fact
brings in a lot more headers too), instead declare a couple structs for

hw: add missing includes hidden by block/aio.h
hw/qdev/core.h being included by core headers means that it was quite

Add the missing inclusions.
