8277171663 mmc: fsl_esdhc_imx: fix config check issue when building in SPL
Should use CONFIG_IS_ENABLED not IS_ENABLED for clock and regulator drivers,
CONFIG_IS_ENABLED will check the CONFIG_SPL_CLK and CONFIG_SPL_DM_REGULATOR
when building SPL.

9bc5666c8a mmc: do not change mode when accessing a boot partition
Accessing the boot partition had been error prone with HS200 and HS400 and
was disabled. The driver first switched to a lesser mode and then switched
the partition access. It was mostly due to a bad handling of the switch and
has been fixed, so let's remove this 'feature'

bb98b8c5c0 mmc: During a switch, poll on dat0 if available and check the final status
The switch operation can sometimes make the bus unreliable, in that case
the send_status parameter should be false to indicate not to poll using
CMD13. If polling on dat0 is possible, we should use it to detect the end
of the operation.
At the end of the operation it is safe to use CMD13 to get the status of
the card. It is important to do so because the operation may have failed.

513e00b64e mmc: When switching partition, use the timeout specified in the ext_csd
The e-MMC spec allows the e-MMC to specify a timeout for the partition
switch command. It can take up to 2550 ms. There is no lower limit to this
value in the spec, but do as the the linux driver does and force it to be
at least 300ms.

cd0b80ec9c mmc: if possible, poll the busy state using DAT0
Using the DAT0 line as a rdy/busy line is an alternative to reading the
status register of the card. It especially useful in situation where the
bus is not in a good shape, like when modes are switched.
This is also how the linux driver behaves.

Note of warning: As per the specification, while polling on DAT0 the CLK
must not turned off: "[...] Without a clock edge the Device (unless
previously disconnected by a deselect command (CMD7)) will force the DAT0
line down, forever. [...]"

b2ffa3320a mmc: omap_hsmmc: reset FSM for DAT and CMD lines if needed before a new command
It sometimes happen that the PSTATE register does not indicate that the
bus is ready when it really is. This usually happens after a mode switch.
In that case it makes sense to reset the FSM handling the CMD and DATA

Also reset the FSMs if the STATE register cannot be cleared. This also
sometimes happens after a mode switch.

ca2abb75a0 spi: Avoid using malloc() in a critical function
In general we should avoid calling malloc() and free() repeatedly in
U-Boot lest we turn it into tianocore. In SPL this can make SPI flash
unusable since free() is often a nop and allocation space is limited.

In any case, these seems no need for malloc() since the number of bytes
is very small, perhaps less than 8.

731ba3c0be blk: Allow control of the block cache in TPL
Generally block devices are not enabled in TPL, but in case they are,
add a Kconfig option for the block cache. This allows the setting (default
off) to be found with CONFIG_IS_ENABLED().

24c2776ba9 sandbox: Correct spi flash operation
Since the SPI nor conversion, 'sf probe' does not work on sandbox. Fix
this by using the expected compatible string in the flash node.

At present this returns but it seems better to just exit sandbox
immediately.
