For Linux, we rename the section so that they are not invoked.
However, it doesn't work for macOS.
Notes:
* Renaming the sections (as the Linux version does) doesn't work
because the section is looked by its flags, not by its names.
* No convenient tools available to alter the relevant bit in
the section flags.
* The constructors are invoked before the program entry point.
As in _xtensa_syscall_handler, a3 was save and reused before
_xtensa_context_save, a3 save in _xtensa_context_save will generate
error.

1. error in A3 push stack
2. when interrupt stack enable, push a12 is xtensa_irq_dispatch
parameter 1, instead of sp. As sp is interrupt stack address set by
`setintstack`, not the interruptee stack address

If CONFIG_FS_LARGEFILE is not defined, the calculation overflows for larger
disks, since blkcnt_t is 32 bits.

iSerialNumber field in the device descriptor can be used to determining the
board when multiple boards connected to the same host. So add feature to change
serial string by board unique ID dynamically.
To use this feature, user must be implement the board_usbdev_serialstr() logic.

Do not use pvconn argument to get the TCP connection pointer because pvconn is
normally NULL for some events like NETDEV_DOWN. Instead, the TCP connection pointer
can be reliably obtained from the corresponding TCP socket.
If a existing file is opened with truncate mode e.g. fopen(file, "w+"),
the file size will be incorrect after writing any data to the file.
Before writing to the first sector, the reading is performed again.
As a result, it makes an invalid file size. When a sector buffer is used,
it must also write to the first sector.
Both the snd_ackcb and snd_datacb callbacks were created and destroyed right after sending every packet.
Whenever TCP_REXMIT event occurred due to TCP send timeout, TCP_REXMIT was ignored because
snd_ackcb callback had been destroyed by the time.
The issue is fixed as follows:
- both the snd_ackcb and snd_datacb callbacks are combined into one snd_cb callback
(the same way as in tcp_send_unbuffered.c).
- the snd_cb callback lives until all requested data (via sendfile) is sent,
including all ACKs and possible retransmissions.
As a positive side effect of the code optimization / fix, sendfile TCP payload throughput is increased.
includes following parts:
add support of sparc in arch/Kconfig
add support of sparc in boards/Kconfig
add sparc dir in arch, add sparc dir in boards
add support of sparc in libs/libc/machine
modify all the coding style problem about saprc
