Subject: bootm: Create a function to run through the bootm states
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e1a24c025c3b065b417bd0dd491cb7000583b334;p=u-boot.git

bootm: Create a function to run through the bootm states

In quite a few places, the bootm command is used to handle a boot. We
want these to be done without needing CONFIG_CMDLINE, so add a new
bootm_run() function to handle this.
