common/armflash: add command to check if image exists
Add a command to the ARM flash support to check if an image exists or
not.
If the image is found, it will return CMD_RET_SUCCESS, else
CMD_RET_FAILURE. This allows hush scripts to conditionally load images.
A simple example:
if afs exists ${kernel_name}; then echo found; else echo \
not found; fi
