From daffb0be2c839f3abe431cd68c772fae0e7e49ca Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 30 Jul 2023 11:17:02 -0600 Subject: bootstd: cros: Add ARM support Support booting ChromiumOS on ARM devices using FIT. Add an entry into the boot implementation which does not require a command line. This can be expanded over time as the bootm code is refactored.
