drivers/i2c/omap24xx_i2c.c: move all local variables to SRAM
At old overo boards TWL4030 RTC irq is connected to gpio112. Unfortunately
this pin is also used for revision detection. Therefore we need to send
shut-up to TWL4030 to avoid reading wrong revision. In SPL this must
be done before SDRAM is set up because the type of SDRAM is revision dependent.
By this patch it is ensured that all variables used by omap24xx_i2c.c are
located in SRAM.

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.

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.

not bundled in all four steps implicitly, but issued once

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.

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.

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.

Revert "SBC8548: fix address mask to allow 64M flash"
This reverts commit
ccf1ad535ae1c0dc2d466235c668adbdfe3a55b7.
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.

MPC85xxCDS: Fix missing LCRR_DBYP bits for 66-133MHz LBC
These boards were meaning to deploy this value:
#define LCRR_DBYP 0x80000000
but were missing a zero, and hence toggling a bit that
lands in an area marked as reserved in the 8548 reference
manual.
According to the documentation, LCRR_DBYP should be used as:
PLL bypass. This bit should be set when using low bus
clock frequencies if the PLL is unable to lock. When in
PLL bypass mode, incoming data is captured in the middle
of the bus clock cycle. It is recommended that PLL bypass
mode be used at frequencies of 83 MHz or less.
So the impact would most likely be undefined behaviour for
LBC peripherals on boards that were running below 83MHz LBC.
Looking at the actual u-boot code, the missing DBYP bit was
meant to be deployed as follows:
Between 66 and 133, the DLL is enabled with an
override workaround.
In the future, we'll convert all boards to use the symbolic
DBYP constant to avoid these "count the zeros" problems, but
for now, just fix the impacted boards.

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

mmc: tegra2: Implement card-detect hook.
On Tegra2, card-detection is implemented by passing the card-detection
GPIOs to the MMC driver at initialization time. Instead of implementing
the board_mmc_getcd() function, use the card-detect hook and allow
boards to override it by providing their own board_mmc_getcd()
implementation.

mmc: fsl_esdhc: Implement card-detect hook.
This card-detect hook probably doesn't work. Perhaps somebody with more
knowledge about the hardware can comment on this. I think that perhaps
even the complete code from esdhc_init() could go into the getcd()
function instead or mmc_getcd() needs to be called at some later time
after mmc_init(), which, however, would require many other drivers to
change.
In addition to implementing the hook, this patch also removes the call
to the board_mmc_getcd() function which is now called from the MMC
framework and is no longer required here.

mmc: Implement card detection.
Check for card detect each time an MMC/SD device is initialized. If card
detection is not implemented, this code behaves as before and continues
assuming a card is present. If no card is detected, has_init is reset
for the MMC/SD device (to force initialization next time) and an error
is returned.

mmc: Change board_mmc_getcd() function prototype.
The new API no longer uses the extra cd parameter that was used to store
the card presence state. Instead, this information is returned via the
function's return value. board_mmc_getcd() returns -1 to indicate that
no card-detection mechanism is implemented; 0 indicates that no card is
present and 1 is returned if it was detected that a card is present.
The rationale for this change can be found in the following email
thread:
http://lists.denx.de/pipermail/u-boot/2011-November/110180.html
In summary, the old API was not consistent with the rest of the MMC API
which always passes a struct mmc as the first parameter. Furthermore the
cd parameter was used to mean "card absence" in some implementations and
"card presence" in others.
