129adf5bf4 mmc: dw_mmc: Probe the MMC from OF
Rework the driver to probe the MMC controller from Device Tree
and make it mandatory. There is no longer support for probing
from the ancient qts-generated header files.

This patch now also removes previous temporary workaround.

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.

236efe36be Revert "fdt: Fix fdtdec_get_addr_size() for 64-bit"
This reverts commit 5b34436035.

This function has a few problems. It calls fdt_parent_offset() which as
mentioned in code review is very slow.

https://patchwork.ozlabs.org/patch/499482/
https://patchwork.ozlabs.org/patch/452604/

It also happens to break SPI flash on Minnowboard max which is how I noticed
that this was applied. I can send a patch to tidy that up, but in any case
I think we should consider a revert until the function is better implemented.

hardcoded values in the U-Boot code. Since we don't have a proper reset

support using device tree and move it to a common place, so that we

aad78d2732 dm: x86: pci: Convert chromebook_link to use driver model for pci
Move chromebook_link over to driver model for PCI.

This involves:
- adding a uclass for platform controller hub
- removing most of the existing PCI driver
- adjusting how CPU init works to use driver model instead
- rename the lpc compatible string (it will be removed later)

This does not really take advantage of driver model fully, but it does work.
Furture work will improve the code structure to remove many of the explicit
calls to init the board.
