- do more POSIX:
- use DIR instead of struct dirent
- use (struct dirent)->d_name instead of (struct dirent)->name
- switch to a new layout for U_BOOT_CMD:
- use C99 initializers to be able to add more fields to the
command struct
- add aliases for commands (needed mainly for help -> ? and test -> [
- This is not done for all commands yet, but the compiler will tell you ;)
some main.c cleanup:
- move the parser used when hush is disabled to parser.c
- move readline related functions to readline.c (with cmdline editing)
and readline_simple.c (no cmdline editing)
