u-boot-update: import additional cmdline parameters
/etc/kernel/cmdline
can be used to store additional kernel
command-line parameters that might be required for a specific target.
However, this file is ignored by u-boot-update
, which only sources
/etc/default/u-boot
.
This would require different processes for u-boot targets and other
ones. Therefore, having both kinds of targets using the contents of
/etc/kernel/cmdline
would improve portability.
This commit imports the cmdline
file and appends its contents to the
parameters found in /etc/default/u-boot
.
