From 72119aa14a1c81b5dd2996fc86c80f8d0e2c456d Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 31 May 2019 15:22:44 +0200 Subject: [PATCH] mmc: Avoid HS400 mode when accessing boot partitions U-Boot code currently only applies this restriction to HS200 mode, extend this to HS400 mode as well. Currently U-Boot code not support accessing boot partition in HS200/400 mode. This needs more check.
