- implemented SYS_DRVINFO syscall and version handling for the semihosting driver - removed a support of old oocd versions renamed kconfig options: - CONFIG_SEMIHOSTFS_HOST_PATH_MAX_LEN to CONFIG_VFS_SEMIHOSTFS_HOST_PATH_MAX_LEN - CONFIG_SEMIHOSTFS_MAX_MOUNT_POINTS to CONFIG_VFS_SEMIHOSTFS_MAX_MOUNT_POINTS

If enabled, select function is provided by the VFS component, and can be used
|

on peripheral file descriptors (such as UART) and sockets at the same time.

If disabled, the default select implementation will be provided by LWIP for

sockets only.

Disabling this option can reduce code size if support for "select" on UART file

descriptors is not required.
