The minimum granularity of PMP is 4 bytes, it is small than 4KB page
size, therefore, the pmp checking would be ignored if its range doesn't
start from the alignment of one page. This patch detects the pmp entries
and sets the small page size to TLB if there is a PMP entry which cover

causes the PMP wrong checking due to the minimum granularity of PMP is

that means, we always use the start address of the page to check PMP for

platform where all platform specific functionality is provided based
on FDT passed by previous booting stage. The support was added in

to use fw_dynamic type images as well.

Hou Weiying fdd33b86b2 riscv: Fix bug in setting pmpcfg CSR for RISCV64
First, sizeof(target_ulong) equals to 4 on riscv32, so this change
does not change the function on riscv32. Second, sizeof(target_ulong)
equals to 8 on riscv64, and 'reg_index * 8 + i' is not a legal
pmp_index (we will explain later), which should be 'reg_index * 4 + i'.

If the parameter reg_index equals to 2 (means that we will change the
value of pmpcfg2, or the second pmpcfg on riscv64), then
pmpcfg_csr_write(env, 2, val) will map write tasks to
pmp_write_cfg(env, 2 * 8 + [0...7], val). However, no cfg csr is indexed
by value 16 or 23 on riscv64, so we consider it as a bug.

We are looking for constant (e.g., define a new constant named
RISCV_WORD_SIZE) in QEMU to help others understand code better,
but none was found. A possible good explanation of this literal is it is
the minimum word length on riscv is 4 bytes (32 bit).

Stefano Garzarella c44a33e2fe configure: silence 'shift' error message in version_ge()
If there are less than 2 arguments in version_ge(), the second
'shift' prints this error:
    ../configure: line 232: shift: shift count out of range

As Eric suggested, we can use 'shift ${2:+2}' which works out to
'shift 2' if $2 is set, or 'shift' (implicitly shift 1) if $2
is not set.

This patch replaces both 'shift; shift' occurrences in version_ge()
with 'shift ${2:+2}'.

This does not implement all opcodes related to div/sqrt as specified in

Move FSR/FCR register accessors from core opcodes to FPU2000 opcodes as
they are FPU2000-specific.

Max Filippov 5680f20756 target/xtensa: rename FPU2000 translators and helpers
Add _s suffix to all FPU2000 opcode translators and helpers that also
have double-precision variant to unify naming and allow adding DFPU
implementations. Add _fpu2k_ to the names of helpers that will have
different implementation for the DFPU .

Max Filippov ed07f685ad target/xtensa: support copying registers up to 64 bits wide
FLIX dependency breaking code assumes that all registers are 32 bit
wide. This may not always be correct.
Extract actual register width from the associated register file and use
it to create temporaries of correct width and generate correct data
movement instructions.

Max Filippov ee659da21a target/xtensa: add geometry to xtensa_get_regfile_by_name
Register file name may not uniquely identify a register file in the set
of configurations. E.g. floating point registers may have different size
in different configurations. Use register file geometry as additional
identifier.

Max Filippov fbcc38e4cb softfloat: add xtensa specialization for pickNaNMulAdd
pickNaNMulAdd logic on Xtensa is to apply pickNaN to the inputs of the
expression (a * b) + c. However if default NaN is produces as a result
of (a * b) calculation it is not considered when c is NaN.
So with two pickNaN variants there must be two pickNaNMulAdd variants.
In addition the invalid flag is always set when (a * b) produces NaN.
