150c24936b Tegra20: Move some include files to arch-tegra for sharing with Tegra30
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.

All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

47f7bcae8c SPL: Move the omap SPL framework to common/spl
Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards.  We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/.  We leave
the NAND one in-place as we plan to replace it later in this series.

We use common/spl to avoid linker problems with respect to merging
constant strings in objects.   Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

29159057a1 mmc: detect boot sectors using EXT_CSD_BOOT_MULT too
Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT
bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such
devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set.

Note that the Linux kernel enables access to boot partitions solely based
on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only
influences access to "general" partitions.

eMMC devices affected by this issue exist on various NVIDIA Tegra
platforms (and presumably many others too), such as Harmony (plug-in eMMC),
Seaboard, Springbank, and Whistler (plug-in eMMC).

95b01c47ed mmc: Remove incorrect cmd->flags usage
There were a couple of drivers that were actually using the flags

97ed12cedf MX28: MMC: Avoid DMA DCache race condition
This patch prevents dcache-related problem. The problem manifested
itself on the SPI driver, this is just a port to the MMC driver.

The scenario is the same. In case an "mmc read" is issued to a
buffer which was written right before it and data cache is enabled,
the cache eviction might happen during the DMA transfer into the
buffer, therefore corrupting the buffer. Clear any cache lines that
might contain the buffer to prevent such issue.

cdfd1ac6df mmc: fix capacity calculation when EXT_CSD_SEC_CNT is used
Since the type of "ext_csd" was array of char, the following
calculation might fail when the value of ext_csd[EXT_CSD_SEC_CNT]
was minus.

	capacity = ext_csd[EXT_CSD_SEC_CNT] << 0
			| ext_csd[EXT_CSD_SEC_CNT + 1] << 8
			| ext_csd[EXT_CSD_SEC_CNT + 2] << 16
			| ext_csd[EXT_CSD_SEC_CNT + 3] << 24;

So, this patch changes the type of "ext_csd" to array of u8.

The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so
disable it globally for this architecture. This avoids setting no_snoop for all

fsl_esdhc_mmc_init() is used on i.MX, like in
arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().

Since no_snoop was only used on i.MX, get rid of it BTW.

For FSL low-end processors (VVN2.2), in order to detect the SD card,
we should enable PEREN, HCKEN and IPGEN to enable the clock.
Otherwise, after booting the u-boot, and then inserting the SD card,
the SD card can't be detected.
For SDHC VVN2.3 IP, these bits are reserved, and SDCLKEN is used.
And when accessing to these reserved bit, no any impact happened.

40242bc394 mmc:fix Call mmc_init() when executing mmc_get_dev()
This code adds call to mmc_init(), for partition related commands (e.g.
fatls, fatinfo etc.).

It is safe to call mmc_init() multiple times since mmc->has_init flag
prevents from multiple initialization.

The FAT related code calls get_dev high level method and then uses
elements from mmc->block_dev, which is uninitialized until the mmc_init
(and thereof mmc_startup) is called.

This problem appears on boards, which don't use mmc as the default
place for envs

bbbc1ae921 ARM:OMAP+:MMC: Add parameters to MMC init
Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency.  While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board.  The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.

but in while(), didn't check that flag.
So sdhci controller didn't work fine.
CMD6 didn't always complete.

So add the quirks for broken r1b response
and add the timeout value to prevent the infinite loop.

Some MMC cards, like my ancient 32.0MB SanDisk RS-MMC cards had issue if b_max

7a5b80297b mmc: fsl_esdhc: Poll until card is not busy anymore
This patch imports parts of two patches from the Freescale U-Boot with the following
commit messages:

ENGR00156405 ESDHC: Add workaround for auto-clock gate errata ENGcm03648
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=e436525a70fe47623d346bc7d9f08f12ff8ad787
The errata, not applicable to USDHC, causes ESDHC to shut off clock to the card
when auto-clock gating is enabled for commands with busy signalling and no data
phase. The card might require the clock to exit the busy state, so the workaround
is to disable the auto-clock gate bits in SYSCTL register for such commands. The
workaround also entails polling on DAT0 bit in the PRSSTAT register to learn when
busy state is complete. Auto-clock gating is re-enabled at the end of busy state.

ENGR00156670-1 ESDHC/USDHC: Remove delay before each cmd and some bug fixes
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=a77c6fec8596891be96b2cdbc742c9824844b92a
Removed delay of 10 ms before each command. There should not be a need to have this
delay after the ENGR00156405 patch that polls until card is not busy anymore before
proceeding to next cmd.

This patch imports the polling part of both patches. The auto-clock gating code
don't apply for i.MX6 as implemented in these two patches.

SYSCTL_RSTA was defined twice. Remove one definition.

25c719e2c3 mmc: omap: handle controller errors properly
According to OMAP3 TRM, when the controller reports certain errors,
driver must perform a software reset. This is done by setting a bit
in SYSCTL and waiting it to clear:
- SRC on command timeout (CTO)
- SRD on data errors (DTO, DCRC and DEB)

This fixes a problem seen on OMAP3 pandora board with some cards
that won't work with a message printed multiple times:
  timedout waiting on cmd inhibit to clear

Code loosely based on Linux omap_hsmmc driver.

b1e725f2c6 mmc: omap: follow TRM procedure to power on cards
According to OMAP3 TRM, PBIASLITEPWRDNZ bits must be cleared while MMC
power supply is being enabled and is ramping up (those bits might be
left set by the previous bootloader). It doesn't say what happens if
this procedure is violated, but better not to risk here and do things
as required.
