Current fmc model of AST2500 EVB and AST2600 EVB can't emulate quad
mode properly so fix them using equivalent mx25l25635e and mx66u51235f
respectively.
These default settings still can be overridden using the 'fmc-model'
command line option.

When mapped POSIX ACL is used, we are ignoring errors when trying
to remove a POSIX ACL xattr that does not exist. On Linux hosts we
would get ENODATA in such cases, on macOS hosts however we get
ENOATTR instead.
As we can be sure that ENOATTR is defined as being identical on Linux
hosts (at least by qemu/xattr.h), it is safe to fix this issue by
simply comparing against ENOATTR instead of ENODATA.
This patch fixes e.g. a command on Linux guest like:

Linux and macOS only share some errno definitions with equal macro
name and value. In fact most mappings for errno are completely
different on the two systems.
This patch converts some important errno values from macOS host to
corresponding Linux errno values before eventually sending such error
codes along with 'Rlerror' replies (if 9p2000.L is used that is). Not
having translated errnos before violated the 9p2000.L protocol spec,
which says:
"
size[4] Rlerror tag[2] ecode[4]
... ecode is a numerical Linux errno.
"
https://github.com/chaos/diod/wiki/protocol#lerror----return-error-code
This patch fixes a bunch of misbehaviours when running a Linux client
on macOS host. For instance this patch fixes:
mount -t 9p -o posixacl ...
on Linux guest if security_mode=mapped was used for 9p server, which
refused to mount successfully, because macOS returned ENOATTR==93
when client tried to retrieve POSIX ACL xattrs, because errno 93
is defined as EPROTONOSUPPORT==93 on Linux, so Linux client believed
that xattrs were not supported by filesystem on host in general.

The 'rdev' field in 9p reponse 'Rgetattr' is of type dev_t,
which is actually a system dependant type and therefore both the
size and encoding of dev_t differ between macOS and Linux.
So far we have sent 'rdev' to guest in host's dev_t format as-is,
which caused devices to appear with wrong device numbers on
guests running on macOS hosts, eventually leading to various
misbehaviours on guest in conjunction with device files.
This patch fixes this issue by converting the device number from
host's dev_t format to Linux dev_t format. As 9p request
'Tgettattr' is exclusive to protocol version 9p2000.L, it should
be fair to assume that 'rdev' field is assumed to be in Linux dev_t
format by client as well.

The 'synth' driver's root node and the 'synth' driver's first
subdirectory node falsely share the same inode number (zero), which
makes it impossible for 9p clients (i.e. 9p test cases) to distinguish
root node and first subdirectory from each other by comparing their QIDs
(which are derived by 9p server from driver's inode numbers).
Fix this issue by using prefix-increment instead of postfix-increment
operator while generating new inode numbers for subdirectories and files.

This was tested by first creating an emulated TPM device:
swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \
--ctrl type=unixio,path=swtpm-sock
Then launching QEMU with:
-chardev socket,id=chrtpm,path=swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-device tpm-tis-device,tpmdev=tpm0
The TPM device can be seen in the memory tree and the generated device

Two non-subsequent PTEs can be mapped to subsequent paddrs. In this
case, walk_pte will erroneously merge them.
Enforce the split up, by tracking the virtual base address.
Let's say we have the mapping:
0x81200000 -> 0x89623000 (4K)
0x8120f000 -> 0x89624000 (4K)
Before, walk_pte would have shown:
vaddr paddr size attr

0000000081200000 0000000089623000 0000000000002000 rwxu-ad
as it only checks for subsequent paddrs. With this patch, it becomes:

Commit 7c28f4da20 ("RISC-V: Don't add NULL bootargs to device-tree")
tried to avoid adding *NULL* bootargs to device tree, but unfortunately
the changes were entirely useless, due to MachineState::kernel_cmdline
can't be NULL at all as the default value is given as an empty string.
(see hw/core/machine.c::machine_initfn()).
Note the wording of *NULL* bootargs is wrong. It can't be NULL otherwise
a segfault had already been observed by dereferencing the NULL pointer.
It should be worded as *empty" bootargs.

The Arm SMMUv3 includes an optional feature equivalent to the CPU
FEAT_BBM, which permits an OS to switch a range of memory between
"covered by a huge page" and "covered by a sequence of normal pages"
without having to engage in the traditional 'break-before-make'
dance. (This is particularly important for the SMMU, because devices
performing I/O through an SMMU are less likely to be able to cope with
the window in the sequence where an access results in a translation
fault.) The SMMU spec explicitly notes that one of the valid ways to
be a BBM level 2 compliant implementation is:
* if there are multiple entries in the TLB for an address,
choose one of them and use it, ignoring the others
Our SMMU TLB implementation (unlike our CPU TLB) does allow multiple
TLB entries for an address, because the translation table level is
part of the SMMUIOTLBKey, and so our IOTLB hashtable can include
entries for the same address where the leaf was at different levels
(i.e. both hugepage and normal page). Our TLB lookup implementation in
smmu_iotlb_lookup() will always find the entry with the lowest level
(i.e. it prefers the hugepage over the normal page) and ignore any
others. TLB invalidation correctly removes all TLB entries matching
the specified address or address range (unless the guest specifies the
leaf level explicitly, in which case it gets what it asked for). So we
can validly advertise support for BBML level 2.
Note that we still can't yet advertise ourselves as an SMMU v3.2,
because v3.2 requires support for the S2FWB feature, which we don't
yet implement.
