The mpc85xx repuires a special layout on the memory device that is
connected to the eSDHC controller interface. But the file spl_mmc.c
didn't handle this specfic case, there needs a special treatmen, in
the powerpc drictory. So, there is no longer to keep spl_mmc.c on
mpc85xx, CONFIG_SPL_FRAMEWORK is not set.

When CONFIG_SPL_MMC_SUPPORT is set and CONFIG_SPL_FRAMEWORK is not
set, there was an error in drivers/mmc/spl_mmc.c:

drivers/mmc/libmmc.o:(.got2+0x8): undefined reference to `spl_image'.

Now, the solution is to move the file "spl_mmc.c" to directory "common/spl".

Sparc only really sets up the ramdisk, but we should still use
image_setup_linux() so that setup is common across all architectures
that use the FDT.

Cover-letter
Introduce a common image_setup_linux() function
This series continues the work to tidy up the image code. Each
architecture has its own code for setting up ready for booting linux.
An attempt is made here to unify these in a single image_setup_linux()
function.

The part of the image code that deals with FDT is split into image-fdt.c
and a few tweaks are added to make FIT images more viable in SPL.

With fewer #ifdefs the code is more readable and more of the code is
compiled for all boards. Add defines in the header file to control
what features are enabled, and then use if() instead of #ifdef.

This seems to be a common function for several architectures, so create
a common function rather than duplicating the code in each arch.

Also make an attempt to avoid introducing #ifdefs in the new code, partly
by removing useless #ifdefs around function declarations in the image.h
header.

The image file is still very large, and some of the code is only used when

The fit_handle_file() function is quite long - split out the part that
loads and checks a FIT into its own function. We will use this
function for storing public keys into a destination FDT file.

The error handling is currently a bit repetitive - tidy it.

Signed-off-by: Simon Glass <sjg@chromium.org>

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.

Adjust the cost so that translating from a U-Boot address to a pointer uses
map_sysmem(). This allows bootm to work correctly on sandbox.

Note that there are no exhaustive tests for this code on sandbox, so it is
possible that some dark corners remain.

Rather than repeat the line
 #if defined(CONFIG_TIMESTAMP) || defined(CONFIG_CMD_DATE) || \
	defined(USE_HOSTCC)

everywhere, put this in a header file and #define IMAGE_ENABLE_TIMESTAMP
to either 1 or 0. Then we can use a plain if() in most code and avoid
the #ifdefs.

The compiler's dead code elimination ensures that the result is the same.

Iterating through subnodes with libfdt is a little painful to write as we
need something like this:

for (depth = 0, count = 0,
	offset = fdt_next_node(fdt, parent_offset, &depth);
     (offset >= 0) && (depth > 0);
     offset = fdt_next_node(fdt, offset, &depth)) {
	if (depth == 1) {
		/* code body */
	}
}

Using fdt_next_subnode() we can instead write this, which is shorter and
easier to get right:

for (offset = fdt_first_subnode(fdt, parent_offset);
     offset >= 0;
     offset = fdt_next_subnode(fdt, offset)) {
	/* code body */
}

Also, it doesn't require two levels of indentation for the loop body.
