This gives compatability with SD Cards using the old U-Boot scheme of an initial
VFAT part for kernel and then ext2. If you put the kernel you actually want to
use in /boot/uImage.bin in the ext2 partition, it can boot these cards then.

We need putc even when we are operating entirely from steppingstone.
Arrange that the board-specific putc code is in a section that goes into
steppingstone, and adapt the utils.c putc() so that it no longer needs to
indirect through the board_api struct that is in main memory.

This adds the memory testing code to Qi. It tests the range of memory with
several constants and then a 32-bit walking 1 pattern, and repeats forever.
The entire main SDRAM can be tested due to the fact this runs out of
steppingstone only and does not need to store anything outside of it.
It introduces a steppingstone-based stack for use entirely in steppingstone.

Improve glamo-mmc so that it uses MMC_READ_MULTIPLE_BLOCK and copes with
64 blocks in one command (and STOP sent after each set), instead of sending
a new command per-block

This heavily adapts the Samsung U-Boot hs_mmc code and combines it with the
SD / SDHC startup code written for glamo-mci stuff that is known to work OK
with common SD and SDHC.
tla01 is changed to use the implementation.
