From 17241ea0543a4c998f79bde27b8a6047c8d84d0a Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Tue, 3 Sep 2019 16:16:50 +0200 Subject: [PATCH] spl: mmc: Add option to set eMMC HW boot partition This change allows setting pre-defined eMMC boot partition for SPL eMMC booting. It is necessary in the case when one wants to boot (through falcon boot) from eMMC after loading SPL from other memory (like SPI-NOR).
