sandbox: fs: Add support for saving files to host filesystem
This allows write of files from the host filesystem in sandbox. There is
currently no concept of overwriting the file and removing its existing
contents - all writing is done on top of what is there. This means that
writing 10 bytes to the start of a 1KB file will only update those 10
bytes, not truncate the file to 10 byte slong.

sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host file
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
to read an FDT from a host file on start-up.

sandbox: Provide a way to map from host RAM to U-Boot RAM
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
to avoid this. However there are data structures (e.g. struct
bootm_headers) which use pointers. We could with a lot of effort adjust
the structs and all code that uses them to use ulong instead of pointers.
This seems like an unacceptable cost, since our objective with sandbox
is to minimise the impact on U-Boot code while maximising the features
available to sandbox.
Therefore, create a map_to_sysmem() function which converts from a
pointer to a U-Boot address. This can be used sparingly when needed.

Trigger generic board error only when building
At present the generic board error can occur when configuring U-Boot, or
during distclean, but this is incorrect. The existing autoconf.mk may come
from an earlier U-Boot configuration which is about to be overwritten.
Make the error conditional so that it will only be triggered when we are
actually building U-Boot.
This avoids a problem where the system is being reconfigured to remove
CONFIG_SYS_GENERIC_BOARD on an architecture that does not support it.
Currently this will print an error and require the manual removal of
include/autoconf.mk.

imx: iomux-v3: Include PKE and PUE to pad control pull definitions
PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.
By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.
Commit dc88403 "iomux-v3: Place pad control definitions into common file" broke
mx51_efikamx because it made i.MX6's pad control definitions conflict with
i.MX51's.
i.MX51's pad control definitions are actually common to some other i.MX
(25/35/53), so move them to the common iomux-v3.h (just like what is done in
Linux's), and select the correct definitions depending on whether CONFIG_MX6 is
defined or not.

- Homogenize prg_p naming (the reference manuals are not always self-consistent
for that).
- Add missing SCSx and bank registers.
- Fix the number of banks on i.MX53.

- Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the

Another way to fix this is to use -nostdinc and -idirafter to ensure that
