49c3a861d1 bootm: Add subcommands
Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.

This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.

Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).

76da19df5b Added arch_lmb_reserve to allow arch specific memory regions protection
Each architecture has different ways of determine what regions of memory
might not be valid to get overwritten when we boot.  This provides a
hook to allow them to reserve any regions they care about.  Currently
only ppc, m68k and sparc need/use this.

56844a22b7 powerpc: Fix bootm to boot up again with a Ramdisk
Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

"%d" and incorrect arguments.  Others were just annoying, like

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.

This patch fixes eeprom page size so that you can now write more than

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).

Convert PPC specific fdt_relocate() to use lmb for allocation of the device

Provided a weak function that board code can call to do additional
lmb reserves if needed.

Also introduce the concept of bootmap_base to specify the offset in
physical memory that the bootmap is located at.  This is used for
allocations of the cmdline, kernel bd, and device tree as they should
be contained within bootmap_base and bootmap_base + CFG_BOOTMAPSZ.

- raw FDT blob passed
- FDT blob embedded in the legacy uImage
- FDT blob embedded in the new uImage

This patch enables proper raw FDT handling when no FIT imaeg support
is compiled in. This is a bit tricky as we must dected FIT format even
when FIT uImage handling is not enabled as both FIT uImages and raw FDT
blobs use tha same low level format (libfdt).
