[PATCH u-boot v2019.04-aspeed-openbmc v3 0/4] FIT verification

[Joel Stanley]

As part of our effort to enable secure boot in openbmc, this turns on
FIT verification in the SPL and u-boot.

It adjusts the SRAM layout to accommodate the extra code size, moving
the heap to the non-parity checked 24KB of SRAM.

It also modifies the way the SPL is built, including disabling features.

v3 Reorders the patches to put the size reduction changes first, and
then enables signature verification to ensure the build can be bisected.

The ymodem disable patch is dropped, as we fit cleanly under the 64KB
boundary with the feature enabled.

The general cleanup patch is dropped, except for the DOS_PARTITION
change which was added to the SPL cleanup patch. These cleanups will be
posted separately at a later date.
