Subject: bootm: Create a function to run through the bootz states
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3405c9b6a592585db80405d960ec219590689159;p=u-boot.git

bootm: Create a function to run through the bootz states

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