b215614638 mmc: zynq_sdhci: Added qurik to disable high speed
Add quirk to disable high speed incase the high
speed was broken.This solves the issue where the
the controller is used in High Speed Mode and the
the hold time requirement for the JEDEC/MMC 4.41
specification is NOT met.
This timing issue is not on all boards and hence
provided config option to enable it when required.

b8a9bebeec zynq: sdhci: Calculate minimum frequency based on max frequency
Calculate the minimum sd clock based on max clock. This will
be done by add_sdhci() if we pass minimum clock as zero.
It also does based on SD host contoller version.

0f9258228e of: clean up OF_CONTROL ifdef conditionals
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

5a20397b00 mmc: remove the MMC_MODE_HC flag
High capacity support is not a host capability, but a device capability
that is queried via the OCR. The flag in the operating conditions
request argument can just be set unconditionally. This matches the Linux
implementation.

[panto] Hand merged and renumbering MMC_MODE_DDR_52MHz.
