This commit adds support to the sunxi SPL to load u-boot from the internal

This change is necessary to calculate correct checksum for NAND

The A1 SRAM Base differs between sun9i and the others, update sunxi-common.h
to deal with this, so that we do not set the initial stack pointer to point

This avoids the need for the weird undocumented register write I previously
took from the allwiner u-boot sources and which needed #ifdef-ery in start.S
as it needed to be done really early on.

bootm_find_ramdisk_fdt() renamed to bootm_find_images() for readability.

The function bootm_find_ramdisk_fdt() appears to be a simple wrapper for
bootm_find_ramdisk(), bootm_find_fdt(), and now bootm_find_loadables().
I didn't see any other callers entering a bootm_find<thing>, so removing
the wrapper, and condensing these together hopefully makes the code a

Instead of hardcoding -lssl -lcrypto as the flags needed to build
mkimage with FIT signature enabled, use pkg-config when
available. This allows to properly support cases where static linking
is used, which requires linking with -lz, since OpenSSL uses zlib
internally.

We gracefully fallback on the previous behavior of hardcoding -lssl
-lcrypto if pkg-config is not available or fails with an error.

The ARM Trusted Firmware or other security solutions are
eating memory from the top of the physical SDRAM1 space,
moving backward from 0xffffffff, currently occupying e.g.
0xfe000000-0xffffffff with Trusted Firmware.

This solution to reserving memory for secure world is not
optimal, so we need to think of how the secure world and
earlier boot stages should communicate to U-Boot what
memory they are eating up. For now let's just put 16MB
aside.

Also enable the memory test command and define start and
end of the test range so we can check that we actually have
all that memory available and working.
