According to Virtual I/O Spec:
When using legacy interfaces, transitional drivers which have not negotiated VIRTIO_F_ANY_LAYOUT MUST use a single descriptor for the struct virtio_net_hdr on both transmit and receive, with the network data in the following descriptors.

stdint.h is needed in uart_16550.h for some types, e.g. uint32_t,
uintptr_t. Otherwise there will be building issue unless that stdint.h
is added before uart_16550.h by all files which needs uart_16550.h.

for sources that have implemented multiple prog_main,
there is a situation where you don't need to add source files but need to register.
the add_application method is enhanced so that it can be registered without entering SRCS.

the Unix-specific commands used in the CMake implementation of savedefconfig are not
supported on the Windows platform, which will cause compatibility issues.
replace it with CMake implementation, which can be cross-platform and has been verified on Windows.

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.
