47b7fa30c4 mmc: invalidate block cache after hwpart switched successfully
eMMC device has multiple hw partitions both address from zero. However the
mmc driver lacks block cache invalidation for switch hwpart. This causes a
problem that data of current hw partition is cached before switching to
another hw partition. And the following read operation of the latter hw
partition will get wrong data when reading from the addresses that have
been cached previously.

To solve this problem, invalidate block cache after a successful
mmc_switch_part() operation.

2e01fcf17c mmc: sti_sdhci: Fix sdhci_setup_cfg() call.
host->mmc, host->mmc->dev and host->mmc->priv must be set
before calling sdhci_setup_cfg() to avoid hang during mmc
initialization.

Thanks to commit 3d296365e4
("mmc: sdhci: Add support for sdhci-caps-mask") which put
this issue into evidence.

23441fbf2b mmc: stm32_sdmmc2: Increase SDMMC_BUSYD0END_TIMEOUT_US
Increase SDMMC_BUSYD0END_TIMEOUT_US from 1s to 2s to
avoid timeout error during blocks erase on some sdcard

Issue seen on Kingston 16GB :
  Device: STM32 SDMMC2
  Manufacturer ID: 27
  OEM: 5048
  Name: SD16G
  Bus Speed: 50000000
  Mode: SD High Speed (50MHz)

  host capabilities: widths [4, 1] modes [MMC legacy, SD Legacy, MMC High Speed (26MHz), SD High Speed (50MHz), MMC High Speed (52MHz)]
  Rd Block Len: 512
  SD version 3.0
  High Capacity: Yes
  Capacity: 14.5 GiB
  Bus Width: 4-bit
  Erase Group Size: 512 Bytes

Issue reproduced with following command:

STM32MP> mmc erase 0 100000

MMC erase: dev # 0, block # 0, count 1048576 ... mmc erase failed
16384 blocks erased: ERROR

By setting SDMMC_BUSYD0END_TIMEOUT_US at 2 seconds and by adding
time measurement in stm32_sdmmc2_end_cmd() as shown below:

	+start = get_timer(0);
	/* Polling status register */
	ret = readl_poll_timeout(priv->base + SDMMC_STA,
				 status, status & mask,
 				 SDMMC_BUSYD0END_TIMEOUT_US);

	+printf("time = %ld ms\n", get_timer(start));

We get the following trace:

b78d97ea49 mmc: Move tegra loopback disable option to be under tegra
This is a configuration option specific to the tegra controller.

Doing it this way makes it show up directly under the tegra controller
option, indented one level, as "Disable external clock loopback".

The way it is now, it shows up at the end of the controller list, not
indented, as if it's some kind of generic MMC configuration option.
