From 3af5b851b4c66c63ad0036d4a10ea5b67e7827a1 Mon Sep 17 00:00:00 2001 From: Mattijs Korpershoek Date: Thu, 12 Sep 2024 16:00:01 +0200 Subject: [PATCH] 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.
