4abe8e40a7 dm: Convert PCI MMC over to use DM PCI API
At present pci_mmc_init() does not correctly use the PCI function since the
list it passes is not terminated. The array size passed to pci_mmc_init() is
actually not used correctly. Fix this and adjust the pci_mmc_init() to scan
all available MMC devices.

Adjust this code to use the new driver model PCI API.

This should move over to the new MMC uclass at some point.

1aa2d074a7 mmc: update MMC_ERASE argument to match Linux kernel.
Table 41 of the JEDEC standard for eMMC says that bit 31 of
the command argument is obsolete when issuing the ERASE
command (CMD38) on page 115 of this document:
	http://www.jedec.org/sites/default/files/docs/jesd84-B45.pdf

The SD Card Association Physical Layer Simplified Specification also
makes no mention of the use of bit 31.
	https://www.sdcard.org/downloads/pls/part1_410.pdf

The Linux kernel distinguishes between secure (bit 31 set) and
non-secure erase, and this patch copies the macro names from
include/linux/mmc/core.h.

f0b5f23f32 ARM: imx: fsl_esdhc: fix usage of low 4 bits of sysctl register
The low four bits of the SYSCTL register are reserved on the USDHC
controller on i.MX6 and i.MX7 processors, but are used for clocking
operations on earlier models.

Guard against their usage by hiding the bit mask macros on those
processors.

These bits are used to prevent glitches when changing clocks on
i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7.

>From the i.MX6DQ RM:
	To prevent possible glitch on the card clock, clear the
	FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS
	or DVS in System Control Register) or setting RSTA bit.

ecfb0ff812 mmc: atmel: Fix clock configuration
After silencing the prints which were generated when reconfiguring the
clock of the SD/MMC bus, surprisingly, the driver stopped working such
that every attempt to use the SD/MMC bus caused the CPU to get totally
stuck hard. It turns out that the prints generated a short delay, which
was necessary for the CPU to reconfigure the clock without getting stuck.
Thus, this patch adds a short delay after the clock configuration instead.

be90974c43 sunxi: mmc: Fix clk-delay settings

been slightly tweaked, and for sun9i they are completely different then
what we are using.

This commit brings us in sync with what allwinner does, fixing problems
accessing sdcards on some A33 devices (and likely others).

For pre sun9i hardware this makes the following changes:
-At 400Khz change the sample delay from 7 to 0 (first introduced in A31 sdk)
-At 50 Mhz change the sample delay from 5 to 4 (first introduced in A23 sdk)
-Above 50 MHz change the out delay from 2 to 1 (first introduced in A20 sdk)

For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) -
and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB)
the default timeout is to short.

The new value - 4 minutes (240 seconds) - is the same as the one used in
Linux kernel driver. Such fix should be good enough until we come up

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.
