0768b7a872 Consolidate strmhz() implementation
ARM, i386, m68k and ppc all have identical implementations of strmhz().
Other architectures don't provide this function at all.

This patch moves strmhz() into lib_generic, reducing code duplication
and providing a more unified API across architectures.

dc4b0b38d4 Fix printf errors.
The compiler will help find mismatches between printf formats and
arguments if you let it.  This patch adds the necessary attributes to
declarations in include/common.h, then begins to correct the resulting
compiler warnings.  Some of these were bugs, e.g., "$d" instead of
"%d" and incorrect arguments.  Others were just annoying, like
int-long mismatches on a system where both are 32 bits.  It's worth
fixing the annoying errors to catch the real ones.

41c5eaa725 Resize device tree to allow space for board changes and the chosen node
Current code requires that a compiled device tree have space added to the end to
leave room for extra nodes added by board code (and the chosen node).  This
requires that device tree creators anticipate how much space U-Boot will add to
the tree, which is absurd.  Ideally, the code would resize and/or relocate the
tree when it needed more space, but this would require a systemic change to the
fdt code, which is non-trivial.  Instead, we resize the tree inside
boot_relocate_fdt, reserving either the remainder of the bootmap (in the case
where the fdt is inside the bootmap), or adding CFG_FDT_PAD bytes to the size.

cb1c489690 Restore the ability to continue booting after legacy image overwrite
Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

5b2793a3f3 mpc8323erdb: fix EEPROM page size and get MAC from EEPROM
This patch fixes eeprom page size so that you can now write more than
64 bytes at a time.

It also makes the board take MAC addresses, if found, from EEPROM.

User should place up to 4 addresses at offset 0x7f00, for
eth{,1,2,3}addr.  Any unused addresses should be zero.  This group of
four six-byte values should have it's CRC at the end.  crc32 and
eeprom commands can be used to accomplish this.

If CRC fails, MAC addresses come from the environment.  If CRC
succeeds, the environment is overwritten at startup.

14f73ca679 ppc: Add CFG_MEM_TOP_HIDE option to hide memory area that doesn't get "touched"
If CFG_MEM_TOP_HIDE is defined in the board config header, this specified
memory area will get subtracted from the top (end) of ram and won't get
"touched" at all by U-Boot. By fixing up gd->ram_size the Linux kernel
should gets passed the now "corrected" memory size and won't touch it
either. This should work for arch/ppc and arch/powerpc. Only Linux board
ports in arch/powerpc with bootwrapper support, which recalculate the
memory size from the SDRAM controller setup, will have to get fixed
in Linux additionally.

This patch enables this config option on some PPC440EPx boards as a workaround
for the CHIP 11 errata. Here the description from the AMCC documentation:

CHIP_11: End of memory range area restricted access.
Category: 3

Overview:
The 440EPx DDR controller does not acknowledge any
transaction which is determined to be crossing over the
end-of-memory-range boundary, even if the starting address is
within valid memory space. Any such transaction from any PLB4
master will result in a PLB time-out on PLB4 bus.

Impact:
In case of such misaligned bursts, PLB4 masters will not
retrieve any data at all, just the available data up to the
end of memory, especially the 440 CPU. For example, if a CPU
instruction required an operand located in memory within the
last 7 words of memory, the DCU master would burst read 8
words to update the data cache and cross over the
end-of-memory-range boundary. Such a DCU read would not be
answered by the DDR controller, resulting in a PLB4 time-out
and ultimately in a Machine Check interrupt. The data would
be inaccessible to the CPU.

Workaround:
Forbid any application to access the last 256 bytes of DDR
memory. For example, make your operating system believe that
the last 256 bytes of DDR memory are absent. AMCC has a patch
that does this, available for Linux.

This patch sets CFG_MEM_TOP_HIDE for the following 440EPx boards:
lwmon5, korat, sequoia

The other remaining 440EPx board were intentionally not included
since it is not clear to me, if they use the end of ram for some
other purpose. This is unclear, since these boards have CONFIG_PRAM
defined and even comments like this:

PMC440.h:
/* esd expects pram at end of physical memory.
 * So no logbuffer at the moment.
 */

It is strongly recommended to not use the last 256 bytes on those
boards too. Patches from the board maintainers are welcome.

3d61018643 The patch introduces the alternative configuration of the log buffer for the lwmon5 board: the storage for the log-buffer itself is OCM(on-chip memory), the log-buffer header is moved to six GPT registers (PPC440EPX_GPT0_COMP1, ..., PPC440EPX_GPT0_COMP5).
To enable this, alternative, configuration the U-Boot board configuration
file for lwmon5 includes the definitions of alternative addresses for header
(CONFIG_ALT_LH_ADDR) and buffer (CONFIG_ALT_LB_ADDR).

 The Linux shall be configured with the CONFIG_ALT_LB_LOCATION option set,
and has the BOARD_ALT_LH_ADDR and BOARD_ALT_LB_ADDR constants defined in the
lwmon5 board-specific header (arch/ppc/platforms/4xx/lwmon5.h).
