Xilinx: ARM: punt unused clean/distclean targets on board
The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch or board
directories never get used.

common/image.c: align usage of fdt_high with initrd_high
The commit message of a28afca (Add uboot "fdt_high" enviroment variable)
states that fdt_high behaves similarly to the existing initrd_high.
But fdt_high actually has an outstanding difference from initrd_high.
The former specifies the start address, while the later specifies the
end address.
As fdt_high and initrd_high will likely be used together, it'd be nice
to have them behave same. The patch changes the behavior of fdt_high
to have it aligned with initrd_high.
The document of fdt_high in README is updated with an example to
demonstrate the usage of this environment variable.

Xilinx: ARM: update upper memory limit for dt and ramdisk
By default u-boot will try to load the device tree and
the ramdisk into high memory. This sets up the limits
to reserve some high memory (above 512MB) so that the
items are not loaded higher than that.
The Xilinx TRD uses video memory up high for one example
and if these items are loaded up high the Linux kernel
would not be able to access it.
Xilinx: ARM: Removed device tree booting dependency on CONFIG_SYS_BOOTMAPSZ
boot_relocate_fdt() has been changed to support relocation
for device tree memory. so CONFIG_SYS_BOOTMAPSZ is not required
to hotcode the device tree address and on other wards it's not useful
incase of relocating fdt.

Add a new "fdt_high" enviroment variable. This can be used to control (or prevent) the
relocation of the flattened device tree on boot. It can be used to prevent relocation
of the fdt into highmem. The variable behaves similarly to the existing "initrd_high"
variable.

The previous patch makes u-boot use the full accessible size of ram as

This patch adds a function getenv_bootm_mapsize() for obtaining the
size of the early mapped region accessible by the kernel during early
boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined,
defaults to getenv_bootm_size(), which in turn defaults to the size of
RAM.
getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize"

For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low(). Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.

ubifs: Allow ubifsmount volume reference by number
UBI can mount volumes by name or number The current code forces you

From fs/ubifs/super.c
* There are several ways to specify UBI volumes when mounting UBIFS:
* o ubiX_Y - UBI device number X, volume Y;
* o ubiY - UBI device number 0, volume Y;
* o ubiX:NAME - mount UBI device X, volume with name NAME;
