Subject: bootstd: android: Add U-Boot version to cmdline
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3af5b851b4c66c63ad0036d4a10ea5b67e7827a1;p=u-boot.git

bootstd: android: Add U-Boot version to cmdline

When booting into Android fastbootd (a subset of recovery), the default
UI shows the bootloader version in the screen [1].
This is done via the ro.bootloader property which should come from the
bootloader.

Provide the U-Boot version via a kernel commandline argument so that
fastbootd can show it properly on the screen.
