From 3acbc7b2aa14fe19ee341fc91a54849185708274 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Wed, 27 Jan 2021 14:46:47 +0100 Subject: fastboot: mmc: extend flash/erase for both emmc hwpart 1 and 2 Update the code and the configs for eMMC boot and userdata partitions acces - FASTBOOT_MMC_BOOT_SUPPORT: boot partition 1 and 2 (erase/write) - FASTBOOT_MMC_BOOT1_NAME: boot partition 1, default name="mmc0boot0" - FASTBOOT_MMC_BOOT2_NAME: boot partition 2, default name="mmc0boot1" This patch also removes the unnecessary dependency with ARCH_MEDIATEK and EFI_PARTITION.
