according to armv6-m/armv7-m arch reference manual:
the three ISB {<opt>}, DSB {<opt>}, DMB {<opt>} instructions <opt>
field are defined as:
Specifies an optional limitation on the ISB/DSB/DMB operation. Allowered
values are:
Full system ISB/DSB/DMB operation, encoded as option=='1111'. Can be
omitted.
All other encodings of the options are RESERVED.
the "#opt" field of "isb #opt"
So we could remove the options field in Armv7-m platform.
The following are the build error with greenhills compiler:
CC: common/arm_exit.c [asarm] (error #2071) /tmp/gh_001h70j1.si 92: bad parameter
isb 15
------^
[asarm] (error #2071) /tmp/gh_001h70j1.si 112: bad parameter
isb 15
------^
[asarm] (error) errors during processing
According to armv8-m arch reference manual:
the ISB/DMB instruction's "opt" encoding rule is same as
armv6-m/armv7-m, but the "DSB" instruction is different, in armv8-m, the
"DSB {<opt>}" field has two valid encoding options: 0b0000, 0b0100.
and all other encoding options are reserved.
In Armv7-a/Armv8-a, the dsb/dmb option field has 8 valid state value.

The following are the compile error that reported
by GreenHills compiler:
"/mnt/yang/qixinwei_commit/nuttx/include/arch/syscall.h", line 156 (col. 17): error #2036-D:
cannot allocate "reg0" to specified caller-saved register
"/mnt/yang/qixinwei_commit/nuttx/include/arch/syscall.h", line 157 (col. 17): error #2036-D:
cannot allocate "reg1" to specified caller-saved register
Then we fix this greenhills compilation error by explicitly specifying
the registers in the clobber list in the inline assembly code.
This fix is successful in compiling on the
nuttx/boards/arm/mps/mps2-an500/configs/nsh platform and passes
the ostest test.
However, if we keep the implementation the same for both the default
and Greenhills compilers, the default compiler will report the
following two issues:
1. the "sys_call6" function will report compile error when
compiling on "./vendor/qemu/boards/smartspeaker/configs/smartspeaker-knsh"
platform, the detailed error info:
CC: proxies/PROXY_mq_getattr.c In file included from /home/guoshichao/work_profile/vela_os/vela_qemu_1/nuttx/include/sys/syscall.h:35,
from /home/guoshichao/work_profile/vela_os/vela_qemu_1/nuttx/include/syscall.h:30,
from proxies/PROXY_mmap.c:5:

297 | __asm__ __volatile__
| ^~~~~~~
2. when running on qemu-armv7-a platform, the modification to
"smh_call()" function will make the system fail to boot up, so
we need to keep the default compiler implementation and greenhills
compiler implementation separate

(cherry picked from commit cb48b749b1c9cad8cfb96bff7c5e9b6ebf20fc8a)
Some multicore RV chips (mpfs, jh7110 etc) have hart clusters
and globally numbered mhartids. Clusters with single hart or
SMP support can be managed by one NuttX instance. Currently
NuttX expects to use cluster-local ids.
This allows us to get local ids by offsetting mhartids with a
base value.
Note that there are chips (e.g. k230) that use cluster-local
ids directly, so this is not needed for them.

1. For some reasons, the bootloader will set CPU source to BBPLL and enable it,
but there are calibration issues, so we need turn off the BBPLL and do calibration again to fix the issue.

When executing fork() via a system call, the parent's stack gets corrupted
by the child, as during exception return the child loads the parent's
stack pointer from the context save area.
This happens because the full parent stack (including what has been pushed
during the system call) is copied to the child. What should be copied, is
only the user stack of the parent (the kernel stack is not interesting).
Fix this by only copying the parent's user stack to the child; and make
the child return directly to userspace (not via dispatch_syscall).
Simplifies the implementation of dispatch_syscall, making it easier to
understand and maintain. Let the C-compiler do most of the work, instead
of doing everything as inline assembly.
