Alex Kiernan 413b90777f ti: fastboot: Move weak overrides to board files Overriding fastboot_set_reboot_flag() in arch/arm/mach-omap2/boot-common.c leaves it applying all boards that derive from this, not just the ones which have support for Android bootloader flow. Move the weak function override to the relevant board files. Signed-off-by: Alex Kiernan <alex.kiernan@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>		2018-05-30 11:59:21 +02:00

Summary
=======

This document covers various features of the 'dra7xx_evm' build and some
related uses.

eMMC boot partition use
=======================

It is possible, depending on SYSBOOT configuration to boot from the eMMC
boot partitions using (name depending on documentation referenced)
Alternative Boot operation mode or Boot Sequence Option 1/2.  In this
example we load MLO and u-boot.img from the build into DDR and then use
'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to
set boot0 as the boot device.
