6695affe87 risc-v: Add a new option to control exception reason
The number of exception for risc-v is 16 (0 ~ 15)
for the machine ISA version 1.12 or earlier, the number of exception is 20
(0 ~ 19) from the ISA version 1.13. And maybe changed in the future.

Using a dedicated option to control the exception number to allow the earlier
version chip with customized exception number (e.g. 16 ~ 19 used) to define
the exception reason string correctly.

d4bbbe0d0b drivers/pty: support pty write to send signal, like serial driver
The interaction between the shell service in adb and adbd occurs through a pseudo-terminal (pty).
so, when a command is launched through adb shell from a PC, users now have the ability to pause
or kill the launched,application by inputting specific commands CONFIG_TTY_SIGTSTP_CHAR or
CONFIG_TTY_SIGTINT_CHAR, akin to the capabilities provided by nsh.

f2fd0bc148 libs/libc/obstack: revert invalid null byte append to obstack_vprintf
The commit c4d8d937d5 added null byte for
obstack_vprintf and thus to obstack_printf. I probably lost my marbles
but the same test I run previously now won't append null byte at the end
and this "fix" now causes regressions in code using obstack.

For the reference this is the testing code:

  #define _GNU_SOURCE
  #include <obstack.h>
  #include <stdarg.h>
  #include <stdio.h>
  #include <stdlib.h>

  #define obstack_chunk_alloc malloc
  #define obstack_chunk_free free

  static void print(struct obstack *obs, const char *fmt, ...) {
    va_list arg;
    va_start(arg, fmt);
    obstack_vprintf(obs, fmt, arg);
    va_end(arg);
  }

  int main(int argc, char *argv[]) {
    struct obstack obs;
    obstack_init(&obs);

    obstack_printf(&obs, "this %s", "text ");
    obstack_printf(&obs, "is appended");
    print(&obs, " as well as %s", "vprintf text");
    obstack_1grow(&obs, '\0');

    printf("%s\n", (char *)obstack_finish(&obs));

    obstack_free(&obs, NULL);
    return 0;
  }

The output on NuttX without this patch:

  > obstest
  this text

The output on NuttX with this patch:

  > obstest
  this text is appended as well as vprintf text

The output with GlibC:

  $ gcc test.c && ./a.out

b04da1892e libs/libc/obstack: implement ptr and int growing functions
The new API is defined by GNU and implemented in other LibCs, such as
Musl.

This also modifies API of obstack_blank_fast and obstack_1grow_fast.
These are defined as returning void and thus return value here is
incompatibility with other implementations.

4d35c60ba6 rpmsg_port_spi: set mreq to high to trigger next transmission
rpmsg_port_spi_connect can not be used here because peer may have not finished
the last transmission which will keep the sreq gpio in high level, and it will
read an error data frame.
