7e9603e74e i.mx6q: configs: Add fdt_high and initrd_high variables
To be able to load the device tree and initrd correctly, set
the fdt_high and initrd_high environment variables.

Using 0xffffffff implies that the device tree and the initrd
are initially copied to working addresses. This will avoid an
additional copy.

Loading the device tree to 0x30000000 and the initrd to 0x3c000000
should work for both boards, the ARM2 and SabreLite.

Example (SabreLite):

fatload mmc 0:2 0x10000000 uImage
fatload mmc 0:2 0x3c000000 uInitrd
fatload mmc 0:2 0x30000000 board.dtb
bootm 0x10000000 0x3c000000 0x30000000

Note: This requires that the kernel has CONFIG_HIGHMEM enabled.

4394d0c2ee sdhc_boot: Introduce CONFIG_FSL_FIXED_MMC_LOCATION option
Since commit 97039ab98 (env_mmc: Allow board code to override the environment address)
mmc_get_env_addr is a weak-aliased function in common/env_mmc.c

The mmc_get_env_addr implementation that exists at
board/freescale/common/sdhc_boot.c is meant to be used only for PowerPC boards,
but currently it is being used for all platforms that have CONFIG_ENV_IS_IN_MMC defined.

Introduce CONFIG_FSL_FIXED_MMC_LOCATION so that the boards that need to use
the mmc_get_env_addr version from board/freescale/common/sdhc_boot.c could activate
this config option on their board file.

This fixes the retrieval of CONFIG_ENV_OFFSET on non-PowerPC boards.

2996e2dcc0 tegra2: Add support for Compal Paz00 (Toshiba AC100)
The Toshiba AC100 (Compal code-name Paz00, aka Dynabook AZ) is a netbook
derived from the NVIDIA Tegra Harmony reference board. It ships with
Android, but is often repurposed to run Linux. This patch adds just enough
support to get a U-Boot serial console, and the ability access built-in
eMMC and the external SD slot.

v2:
* Rebased on latest HEAD, incorporated changes made to other board files.
* Moved board files from board/nvidia to board/compal.
* Switched to correct odmdata value. This required add the previous patch
  to fix U-Boot's interpretation of the odmdata RAM size field.
* Removed nvmem= from default Linux kernel command-line; no drivers use the
  reserved memory yet, so there's no point reserving it.

25efd99dbb nand_spl: store ecc data on the stack

  Date:   Thu Dec 15 10:55:37 2011 +0100

      nand_spl_simple: store ecc data on the stack

      Currently nand_spl_simple puts it's temp data at 0x10000 offset in SDRAM
      which is likely to contain already loaded data.
      The patch saves the oob data and the ecc on the stack replacing
      the fixed address in RAM.

While nand_spl is on its way out, in favor of spl, there are still
many boards using it, and conversions are gradual.  This allows us
to get rid of CONFIG_SYS_NAND_ECCSTEPS and CONFIG_SYS_NAND_ECCTOTAL now,
which would otherwise be likely to linger unreferenced after a conversion.

It also eliminates a temporary error in the hawkboard_nand build, since
the spl version of the patch removed ECCSTEPS/TOTAL from hawkboard.h, but
the spl conversion is pending (and may be merged via a different tree).

441ea7c67b arm, davinci: Use a common configuration file for da850evm and da850_am18xxevm
In commit 06194b6b65 a separate header
file was introduced for the AM1808 EVM, include/configs/da850_am18xxevm.h.
Before this commit, the da850evm.h configuration file was used for both
the AM1808 and the OMAP-L138 EVMs. The only substantial difference
between the da850evm and the da850_am18xxevm configuration is a single
bit in the hardware revision that is passed to the Linux kernel.

This patch removes include/configs/da850_am18xxevm.h. Instead the
include/configs/da850evm.h configuration is used for AM18xx EVMs and
CONFIG_DA850_AM18X_EVM is defined in boards.cfg.

3e3262bd14 sbc8548: enable support for hardware SPD errata workaround
Existing boards by default have an issue where the LBC SDRAM
SPD EEPROM and the DDR2 SDRAM SPD EEPROM both land at 0x51.

After the hardware modification listed in the README is made,
then the DDR2 SPD EEPROM appears at 0x53.  So this implements
a board specific get_spd() by taking advantage of the existing
weak linkage, that 1st tries reading at 0x53 and then if that
fails, it falls back to the old 0x51.

Since the old dependency issue of "SPD implies no LBC SDRAM"
gets removed with the hardware errata fix, remove that restriction
in the code, so both LBC SDRAM and SPD can be selected.

7e44f2b710 sbc8548: Make enabling SPD RAM configuration work
Previously, SPD configuration of RAM was non functional on
this board.  Now that the root cause is known (an i2c address
conflict), there is a simple end-user workaround - remove the
old slower local bus 128MB module and then SPD detection on the
main DDR2 memory module works fine.

We make the enablement of the LBC SDRAM support conditional on
being not SPD enabled.  We can revisit this dependency as the
hardware workaround becomes available.

Turning off LBC SDRAM support revealed a couple implict dependencies
in the tlb/law code that always expected an LBC SDRAM address.

This has been tested with the default 256MB module, a 512MB
a 1GB and a 2GB, of varying speeds, and the SPD autoconfiguration
worked fine in all cases.

The default configuration remains to go with the hard coded
DDR config, so the default build will continue to work on boards
where people don't bother to read the docs.  But the advantage
of going to the SPD config is that even the small default module
gets configured for CL3 instead of CL4.

5f4c6f0db9 sbc8548: Fix LBC SDRAM initialization settings
These were cloned from the mpc8548cds platform which has
a different memory layout (1/2 the size).  Set the values
by comparing to the register file for the board used during
JTAG init sequence:

	LSDMR1		0x2863B727	/* PCHALL */
	LSDMR2		0x0863B727	/* NORMAL */
	LSDMR3		0x1863B727	/* MRW    */
	LSDMR4		0x4063B727	/* RFEN   */

This differs from what was there already in that the RFEN is
not bundled in all four steps implicitly, but issued once
as the final step.

The other difference seen when comparing vs. the register file init,
is that since the memory is split across /CS3 and /CS4, the dummy
writes need to go to 0xf000_0000 _and_ to 0xf400_0000.

We also rewrite the final LBC SDRAM inits as macros, as there is
no real need for them to be a local variable that is modified
on the fly at runtime.

f0aec4ea33 sbc8548: enable ability to boot from alternate flash
This board has an 8MB soldered on flash, and a 64MB SODIMM
flash module.  Normally the board boots from the 8MB flash,
but the hardware can be configured for booting from the 64MB
flash as well by swapping CS0 and CS6.  This can be handy
for recovery purposes, or for supporting u-boot and VxBoot
at the same time.

To support this in u-boot, we need to have different BR0/OR0
and BR6/OR6 settings in place for when the board is configured
in this way, and a different TEXT_BASE needs to be used due
to the larger sector size of the 64MB flash module.

We introduce the suffix _8M and _64M for the BR0/BR6 and the
OR0/OR6 values so it is clear which is being used to map what
specific device.

The larger sector size (512k) of the alternate flash needs
a larger malloc pool, otherwise you'll get failures when
running saveenv, so bump it up accordingly.

3fd673cf36 sbc8548: relocate 64MB user flash to sane boundary
The current situation has the 64MB user flash at an awkward
alignment; shifted back from 0xfc00_0000 by 8M, to leave an 8MB hole
for the soldered on boot flash @ EOM.  But to switch to optionally
supporting booting off the 64MB flash, the 64MB will then be mapped
at the sane address of 0xfc00_0000.

This leads to awkward things when programming the 64MB flash prior
to transitioning to it -- i.e. even though the chip spans from
0xfb80_0000 to 0xff7f_ffff, you would have to program a u-boot image
into the two sectors from 0xfbf0_0000 --> 0xfbff_ffff so that it was
in the right place when JP12/SW2.8 were switched to make the 64MB on
/CS0. (i.e. the chip is only looking at the bits in mask 0x3ff_ffff)

We also have to have three TLB entries responsible for dealing with
mapping the 64MB flash due to this 8MB of misalignment.

In the end, there is address space from 0xec00_0000 to 0xefff_ffff
where we can map it, and then the transition from booting from one
config to the other will be a simple 0xec --> 0xfc mapping.  Plus we
can toss out a TLB entry.

Note that TLB0 is kept at 64MB and not shrunk down to the 8MB boot
flash; this means we won't have to change it when the alternate
config uses the full 64MB for booting, in TLB0.

af35be6ac9 Revert "SBC8548: fix address mask to allow 64M flash"
This reverts commit ccf1ad535a.

The commit "SBC8548: fix address mask to allow 64M flash"
essentially made this change:

  * OR6:
- *    Addr Mask = 64M = OR6[0:16] = 1111 1100 0000 0000 0
+ *    Addr Mask = 64M = OR6[0:16] = 1111 1000 0000 0000 0

But this makes no sense, as section 13.3.1.2.1 in the
MPC8548ERM v2 clearly indicates the masks:

	1111_1111_1000_0000_0	8 Mbytes
	1111_1100_0000_0000_0	64 Mbytes
	1111_1000_0000_0000_0	128 Mbytes

So the original value was correct, and the commit was invalid,
causing a 128MB mapping for a 64MB flash device.  The problem
rears its head when trying to configure u-boot to have access
to both flash, since the default memory map is:

	FB80_0000 – FF7F_FFFF 32-bits 64MB FLASH SODIMM
	FF80_0000 – FFFF_FFFF 8-bits 8MB FLASH

By extending the mapping of the 64MB flash to 128MB, it now
conflicts with the normal 8MB boot flash, causing issues.

0ecb55132b eXMeritus HWW-1U-1A: Add support for the AT24C128N I2C EEPROM
This EEPROM is hardware-write-protected and used to persist key
information such as the serial number and MAC addresses even if the
primary environment sector in NOR FLASH is overwritten.

During manufacturing, the environment is initialized from Linux and then
the key parameters copied to the EEPROM via U-Boot:

  env export -c -s 0x2000 $loadaddr serial# macaddr mac1addr mac2addr
  eeprom write $loadaddr 0x0000 0x2000

The chip is then locked via hardware for delivery.

When doing a field U-Boot upgrade, the environment is erased and reset
to the defaults to avoid problems with "hwconfig" changes, etc.  After
loading the new U-Boot image, the hardware data is reloaded:

  i2c dev 0
  eeprom read $loadaddr 0x0000 0x2000
  env import -c $loadaddr 0x2000
  saveenv

The first three commands are saved in the "restore_eeprom" variable for
user convenience.  (EG: "run restore_eeprom && saveenv")
