e92029c0f4 env_mmc: support overriding mmc dev from board code
This enables boards to choose where to/from the environment should be
saved/loaded. They can then for example support using the same device
(dynamically) from which the bootloader was launched to load and save
env data and do not have to define CONFIG_SYS_MMC_ENV_DEV statically.

In my use case, the environment needs to be on the same device I
booted from. It can be the eMMC or an optional SD card.
I therefore would override mmc_get_env_dev in the board code, read the
CPU registers to determine where we booted from and return the
corresponding device index.

8d4f11c203 bootm: fix size arg of flush_cache() in bootm_load_os().
Variable _load_end_ points to end address of uncompressed buffer
(*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed
size with sizeof(ulong) is grossly incorrect in flush_cache().
It might lead to access of address beyond valid memory range and hang the CPU.

Tested on MIPS architecture by using compressed(gzip, lzma)
and uncompressed uImage.

72a8cf8dcc Move all command code into its own directory
There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more
logical.

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Unfortunately, with m68k I get this error:

m68k:  +   M5329AFEE

I hope someone can shed some light on what this means. I hope it isn't

Extend the ums command to accept a list of block devices. Each of these
will be exported as a separate LUN. An example use-case would be:

ums 0 mmc 0,0.1,0.2

... which would export LUNs for eMMC 0's user data, boot0, and boot1 HW
partitions. This is useful since it allows the host access to everything
on the eMMC without having to somehow stop the ums command from executing
and restart it with different parameters.

873cc1d777 mmc: store hwpart in the block device
This will allow us to have multiple block device structs each referring
to the same eMMC device, yet different HW partitions.

For now, there is still a single block device per eMMC device. As before,
this block device always accesses whichever HW partition was most recently
selected. Clients wishing to make use of multiple block devices referring
to different HW partitions can simply take a copy of this block device
once it points at the correct HW partition, and use each one as they wish.
This feature will be used by the next patch.

In the future, perhaps get_device() could be enhanced to return a
dynamically allocated block device struct, to avoid the client needing to
copy it in order to maintain multiple block devices. However, this would
require all users to be updated to free those block device structs at some
point, which is rather a large change.

Most callers of mmc_switch_part() wish to permanently switch the default
MMC block device's HW partition. Enhance mmc_switch_part() so that it does
this. This removes the need for callers to do this. However,
common/env_mmc.c needs to save and restore the current HW partition. Make
it do this more explicitly.

Replace use of mmc_switch_part() with mmc_select_hwpart() in order to
remove duplicate code that skips the call if that HW partition is already
selected.

this patch to exist.

adc421e4ce arm: move gd handling outside of C code
As of gcc 5.2.1 for Thumb-1, it is not possible any
more to assign gd from C code, as gd is mapped to r9,
and r9 may now be saved in the prolog sequence, and
restored in the epilog sequence, of any C functions.

Therefore arch_setup_gd(), which is supposed to set
r9, may actually have no effect, causing U-Boot to
use a bad address to access GD.

Fix this by never calling arch_setup_gd() for ARM,
and instead setting r9 in arch/arm/lib/crt0.S, to
the value returned by board_init_f_alloc_reserve().

On the other hand, boot_ramdisk_high() only checks "initrd_high" to

71105f50fe fdt: fix address cell count checking in fdt_translate_address()
Commit: dm: core: Enable optional use of fdt_translate_address()

Enables use of this function as default, but after this it's not
possible to get dev address for the case in which: '#size-cells == 0'

This causes errors when getting address for some GPIOs, for which
the '#size-cells' is set to 0.

Example error:
'__of_translate_address: Bad cell count for gpx0'

Allowing for that case by modifying the macro 'OF_CHECK_COUNTS',
(called from )__of_translate_address(), fixes the issue.

Now, this macro doesn't check, that '#size-cells' is greater than 0.

This is possible from the specification point of view, but I'm not sure
that it doesn't introduce a regression for other configs.

Please test and share the results.
