From f64011e11e283b34b6792165a36c42b8241f2a24 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Sat, 7 Aug 2021 15:07:22 +0200 Subject: [PATCH] board: stemmy: Add basic Fastboot support Make use of the new drivers for ARM U8500 introduced in the U-Boot 2021.10 merge window by adding basic support for USB Fastboot with the "stemmy" board. As a first step this will always boot directly into USB Fastboot for now with the console displayed on the screen to make that obvious. Samsung uses quite strange GPT partition labels on these boards, so also add a bunch of fastboot_partition_alias_* to make this more easy to use.
