* hush: add showvar command for hush shell.Heiko Schocher2008-10-18-0/+6
| | | | | | | | | | | | | | | | | | | | This new command shows the local variables defined in the hush shell: => help showvar showvar - print values of all hushshell variables showvar name ... - print value of hushshell variable 'name' Also make the set_local_var() and unset_local_var () no longer static, so it is possible to define local hush shell variables at boot time. If CONFIG_HUSH_INIT_VAR is defined, u-boot calls hush_init_var (), where boardspecific code can define local hush shell variables at boottime. Signed-off-by: Heiko Schocher <hs@denx.de>
