[U-Boot] [PATCH] fix lib_arm/bootm.c

[Daniel Mack <daniel@caiaq.de>]

Hi,

while digging thru the sources to find out why U-Boot won't start my
Linux kernel, I stumbled over lib_arm/bootm.c and its check for the falg
variable. I wonder how this ever worked as the condition is really heavy
to match unless BOOTM_STATE_OS_GO is 0 which it isn't.

So I guess the patch below is mandatory or you could write an unlikely()
around that check ;)

Best regards,
Daniel
