From 5f2ff607e286ab92ede986d62b39391557d36c61 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20=C5=A0tetiar?= Date: Wed, 18 Mar 2020 15:00:22 +0100 Subject: [PATCH] uboot-sunxi: a64: allow booting directly from eMMC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Current boot script uses hardcoded bootdevice, which allows booting from SD card only, so this patch allows booting directly from eMMC as well. While at it, replace fixed root device with more flexible UUID based probing, so from now on probing order of MMC device doesn't matter.
