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

=======================================================================
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.
