U-Boot image.

But, since the u-boot-spl.img (including the 64 byte header) is loaded
by the SoC as the main image, we need to compensate for the header
length to get a correct entry point.

Thus, we subtract the header size from the destination address, so that
the execution address points at the actual entry point of the image.

The current boards ignore both parameters anyway, so this change shouldn't

mmc: move CONFIG_GENERIC_MMC to Kconfig

Now, CONFIG_GENERIC_MMC seems equivalent to CONFIG_MMC.

Let's create an entry for "config GENERIC_MMC" with "default MMC",
then convert all macro defines in headers to Kconfig.  Almost all
of the defines will go away.

I see only two exceptions:
  configs/blanche_defconfig
  configs/sandbox_noblk_defconfig

They define CONFIG_GENERIC_MMC, but not CONFIG_MMC.  Something
might be wrong with these two boards, so should be checked later.

Anyway, this is the output of the moveconfig tool.

This commit was created as follows:

[1] create a config entry in drivers/mmc/Kconfig

[2] tools/moveconfig.py -r HEAD GENERIC_MMC

[3] manual clean-up of garbage comments in doc/README.* and
    include/configs/*.h

software from being run on products.  The signature is added at the
tail of the second stage loader (= SPL in U-boot terminology).

The size of the second stage loader was 64KB, and it was consistent
across SoCs.  The situation changed when LD20 SoC appeared; it loads
80KB second stage loader, and it is the only exception.

Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is
loaded from the 64KB offset of non-volatile devices.  This means the
signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot
proper image.

Let's move the U-Boot proper image to 128KB offset.  It uses 48KB
for nothing but padding, and we could actually locate the U-Boot
proper at 80KB offset.  However, the power of 2 generally seems a
better choice for the offset address.
