Sam Protsenko f6d245b8c5 arm: am57xx: Fix Linux boot from eMMC
Right now on OMAP5-based boards we have only one partition defined for
Linux boot, which is rootfs. That doesn't work with bootpart=1:2 (that
is defined in include/environment/ti/boot.h). To fix Linux boot we may
either:

 1. Change bootpart to be 1:1
 2. Or add preceding partition, so that rootfs is actually 1:2

Second choice seems more reasonable, as DFU is already using similar
partition table and can rely on bootpart to be 1:2.

This patch adds "bootloader" partition. So now eMMC layout for Linux
boot looks like this:

offset               content                 size          partition
(KiB)                                        (KiB)

=======================================================================

Guard hole appears because U-Boot environment offset was calculated for
Android partition table, which has two additional partitions in place of
that hole ("environment" and "misc" partitions).

This patch also changes rootfs offset from 2 MiB further to 2688 KiB,
so that there won't be any collisions with U-Boot environment when we
flash rootfs.
