For CMD21 tuning data, the 128/64 bytes data may coming in very
short time, before msdc_start_data(), the read data has already
come, in this case, clear MSDC_INT will cause the interrupt disappear
and lead to the thread hang.
the solution is just clear all interrupts before command was sent.

Armada 38x ROM skips the first SD card offset when loading SPL. This
affects the location of the main U-Boot image. SPL MMC code now supports
U-Boot image offset based on run-time detection of the boot partition.
Use this feature to make the same generated image support both SD card
and eMMC boot partition.

On Armada 38x platforms the ROM code loads SPL from offset 0 of eMMC
hardware boot partitions. When there are no boot partitions (i.e. SD
card) the ROM skips the first sector that usually contains the (logical)
partition table. Since the generated .kwb image contains the main U-Boot
image in a fixed location (0x140 sectors by default), we end up with the
main U-Boot image in offset of 1 sector. The current workaround is to
manually set CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x141 to
compensate for that.
This patch uses the run-time detected boot partition to determine the
right offset of the main U-Boot partition. The generated .kwb image is
now compatible with both eMMC boot partition, and SD card main data
partition.

It was observed (on ClearFog Base) that sending MMC APP_CMD returned
an error on the first attempt. The issue appears to be timing related
since even inserting a puts() short debug entry before the execution
added sufficient delay to receive success on first attempt.
Follow the existing quirks pattern to retry if initial issuance
failed so as to not introduce any delay unless needed.

The eSDHC reference clocks should be provided by speed.c in arch/.
And we do not need CONFIG_FSL_ESDHC_USE_PERIPHERAL_CLK option to
select which clock to use. Because we can make the driver to select
the periperhal clock which is better (provides higher frequency)
automatically if its value is provided by speed.c.
This patch is to drop this option and make driver to select clock
automatically. Also fix peripheral clock calculation issue in
fsl_lsch2_speed.c/fsl_lsch3_speed.c.

The QorIQ eSDHC controller supports two reference clocks. They are
platform clock and periperhal clock. The global variable sdhc_clk
has already been used for platform clock.
This patch is to add another global variable sdhc_per_clk for
periperhal clock, which provides higher frequency and is required
to be used for SD UHS and eMMC HS200/HS400 speed modes.

The below patch added eSDHC periperhal clock code initially.
2d9ca2c mmc: fsl_esdhc: Add peripheral clock support
The purpose was to fix up device tree properties "peripheral-frequency"
so that linux could get the periperhal clock by it.
However the implementation on both u-boot and linux was only
for a Freescale SDK release. The linux part implementation had never
been upstreamed. These code should not have been exist on u-boot
mainline.
Let's remove the powerpc part changes but keep the changes in
fsl_esdhc driver. The changes in fsl_esdhc driver could be utilized
to support SD UHS and eMMC HS200/HS400 speed modes for current
Layerscape ARM platforms.
