system/usbmsc: Add support for setting paths bind to LUN at runtime

[JianyuWang0623]

Summary

Add support for setting paths bind to LUN at runtime.

Help

nsh> msconn -h
Usage: msconn [-o OPTION]... [-l LUNs]...
Configures the USB mass storage device and exports the LUN(s).

Supported arguments
  -o
      nc: No const LUN
      ro: Readonly
      rw: Read/Write(default)
  -l
      Device path to export

Examples
  1. Export const LUN(s) only
      msconn
  2. Export /dev/ramx and const LUN(s)
      msconn -l /dev/ramx
  3. Export /dev/ramx without const LUN
      msconn -o nc -l /dev/ramx

Export without const LUN

nsh> msconn -o nc -l /dev/esp32s3flash
mcsonn_main: Creating block drivers
mcsonn_main: Configuring with NLUNS=1
mcsonn_main: handle=0x3fc8ec80
mcsonn_main: Bind LUN=0 to /dev/esp32s3flash
mcsonn_main: Connected
nsh> msdis
msdis: Disconnected

Export with const LUN

nsh> mkrd -m 10 -s 512 640
nsh> msconn
mcsonn_main: Creating block drivers
mcsonn_main: Configuring with NLUNS=2
mcsonn_main: handle=0x3fcdecc8
mcsonn_main: Bind LUN=1 to /dev/esp32s3flash
mcsonn_main: Bind LUN=0 to /dev/ram10
mcsonn_main: Connected
nsh> msdis
msdis: Disconnected

Export without const LUN

nsh> msconn -o nc -l /dev/ram10
mcsonn_main: Creating block drivers
mcsonn_main: Configuring with NLUNS=1
mcsonn_main: handle=0x3fcdecc8
mcsonn_main: Bind LUN=0 to /dev/ram10
mcsonn_main: Connected
nsh>

Impact

• system/usbmsc: Compatible with current usage.

Testing

1. Selftest as above
2. NuttX CI

The CI maybe broken

common/riscv_exit.c: In function 'up_exit':
Error: common/riscv_exit.c:65:33: error: 'tcb' undeclared (first use in this function); did you mean 'tcb_s'?
   65 |   g_running_tasks[this_cpu()] = tcb;
      |                                 ^~~
      |                                 tcb_s
