Subject: pxe: Allow booting without CMDLINE for bootm methods
X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=6d803ec9cc757bda0c48f2fd419cb6878eab92c4;p=u-boot.git

pxe: Allow booting without CMDLINE for bootm methods

Use bootm_run() and booti_run() to boot rather than the command line.
This allows extlinux to be used without CMDLINE being enabled.

Collect any error but do not return it, to match the existing code.
