Added support to find the bootmodes by reading

400a9488d0 arm: make 'MAKEALL -a' distinguish between arm and aarch64
The vexpress_aemv8a is the first aarch64 board in U-Boot.
As it was introduced, it gets built when "MAKEALL -a arm"
is invoked, and fails as this command is run with a 32-bit,
not 64-bit, toolchain as the cross-compiler.

Introduce 'aarch64' as a valid 'MAKEALL -a' argument, treated
as 'arm' for all other intents, and change the architecture
of the vexpress_aemv8a entry in boards.cfg from 'arm' to
'aarch64'.

795611e6ff armv8: Use __aarch64__ rather than CONFIG_ARM64 in some cases
The toolchain sets __aarch64__ for both LE and BE.  In the case of
posix_types.h we cannot reliably use config.h as that will lead to
problems.  In the case of byteorder.h it's clearer to check the EB flag
being set in either case instead.

f4dc714aaa arm64: Turn u-boot.bin back into an ELF file after relocate-rela
While performing relocations on u-boot.bin should be good enough for
booting on real hardware, some simulators insist on booting an ELF file
(and yet don't perform ELF relocations), so convert the relocated
binary back into an ELF file.  This can go away in the future if we
change relocate-rela to operate directly on the ELF file, or if and
when we stop caring about a simulator with this restriction.

8137af19e7 arm64: Add tool to statically apply RELA relocations
ARM64 uses the newer RELA-style relocations rather than the older REL.
RELA relocations have an addend in the relocation struct, rather than
expecting the loader to read a value from the location to be updated.

While this is beneficial for ordinary program loading, it's problematic
for U-Boot because the location to be updated starts out with zero,
rather than a pre-relocation value.  Since we need to be able to run C
code before relocation, we need a tool to apply the relocations at
build time.

In theory this tool is applicable to other newer architectures (mainly
64-bit), but currently the only relocations it supports are for arm64,
and it assumes a 64-bit little-endian target.  If the latter limitation
is ever to be changed, we'll need a way to tell the tool what format
the image is in.  Eventually this may be replaced by a tool that uses
libelf or similar and operates directly on the ELF file.  I've written
some code for such an approach but libelf does not make it easy to poke
addresses by memory address (rather than by section), and I was
hesitant to write code to manually parse the program headers and do the
update outside of libelf (or to iterate over sections) -- especially
since it wouldn't get test coverage on things like binaries with
multiple PT_LOAD segments.  This should be good enough for now to let
the manual relocation stuff be removed from the arm64 patches.

ab71188ce8 mmc: add setdsr support
The eMMC and the SD-Card specifications describe the optional SET_DSR command.
During measurements at our lab we found that some cards implementing this feature
having really strong driver strengts per default. This can lead to voltage peaks
above the specification of the host on signal edges for data sent from a card to
the host.

Since availability of a given card type may be shorter than the time a certain
hardware will be produced it is useful to have support for this command (Alternative
would be changing termination resistors and adapting the driver strength of the
host to the used card.)

Following proposal for an implementation:

- new field that reflects CSD field DSR_IMP in struct mmc
- new field for design specific DSR value in struct mmc
- board code can set DSR value in mmc struct just after registering an controller
- mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set

Additionally the mmc command is extended to make is possible to play around with different
DSR values.

The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default
DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for
instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after
calling fsl_esdhc_initialize() for the eMMC.

Bounce buffer requires to add its definition (CONFIG_BOUNCE_BUFFER) in

and linker will fail to build resulting executable.

"void *":

5c2859cdc3 sandbox: Allow reading/writing of RAM buffer
It is useful to be able to save and restore the RAM contents of sandbox
U-Boot either for setting up tests, for later analysys, or for chaining
together multiple tests which need to keep the same memory contents.

Add a function to provide a memory file for U-Boot. This is read on
start-up and written when shutting down. If the file does not exist
on start-up, it will be created when shutting down.

c5a62d4a7b sandbox: Add -i option to enter interactive mode
Normally when U-Boot starts with a command (-c option) it quits when the
command completes. Normally this is what is requires, since the test is
likely complete.

Provide an option to jump into the console instead, so that debugging or
other tasks may be performed before quitting.

91b136c798 sandbox: Allow the console to work earlier
With sandbox, errors and problems may be reported before console_init_f()
is executed. For example, an argument may not parse correctly or U-Boot may
panic(). At present this output is swallowed so there is no indication what
is going wrong.

Adjust the console to deal with a very early sandbox setup, by detecting that
there is no global_data yet, and calling os functions in that case.

88bd0e9d15 sandbox: Implement the bootm command for sandbox
When sandbox does a 'bootm' to run a kernel we cannot actually execute it.
So just exit sandbox, which is essentially what U-Boot does on other archs.
Also, allow sandbox to use bootm on any kernel, so that it can be used
to test booting of kernels from any architecture.
