Hi Shawn,
This patch enumerates dwmci and set auto stop command during

This patch set is based on:
"EXYNOS: mmc: support DesignWare Controller for Samsung-SoC", which
is merged in u-boot-mmc.
This patch enables and initialises DWMMC for SMDK5250.
Supports both FDT and non-FDT. This patch creates a new file

At present this only checks working_fdt, but we want to check other FDTs
also. So add the FDT to check as a parameter to fdt_valid().

With sandbox it is tricky to add an FDT to the image at build time (or
later) since we build an ELF file, not a plain binary, and the address
space of the whole U-Boot is not accessible in the emulated memory map
of sandbox.
Sandbox can read files directly from the host, though, so add an option

In many cases, pointers to memory are passed around, and these pointers
refer to U-Boot memory, not host memory. This in itself is not a
problem.
However, in a few places, we cast that pointer back to a ulong (being
a U-Boot memory address). It is possible to convert many of these cases

Rather than needing to call one of many hashing algorithms in U-Boot,
provide a function hash_block() which handles this, and can support all
available hash algorithms.
Once we have md5 supported within hashing, we can use this function in
the FIT image code.

Much of the image code uses addresses as ulongs and pointers interchangeably,
casting between the two forms as needed.
This doesn't work with sandbox, which has a U-Boot RAM buffer which is
separate from the host machine's memory.

When signing images it is sometimes necessary to sign with different keys

RSA provides a public key encryption facility which is ideal for image

Add workaround for the following ARM errata: 743622 and 751472.
The motivation for this change is the following kernel commit 62e4d357a
