When enabling the new mmc timing mode, we inadvertently clear all the
remaining bits in the new timing mode register. The bits cleared
include a default phase delay on the output clock. The BSP kernel
states that the default values are supposed to be used. Clearing them
results in decreased performance or transfer errors on some boards.

A patch for NAND uclass support was proposed about half a year ago:
https://patchwork.ozlabs.org/patch/722282/
It was not merged and I do not see on-going work for this.
Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc
way and give lots of crappy CONFIG options for base addresses and
properties, which are supposed to be specified by DT. This is painful.
This commit just provides a probe hook to retrieve "reg" from DT and
allocate private data in a DM manner. This DT driver is not essentially
a NAND driver, in fact it is (ab)using UCLASS_MISC. Once UCLASS_NAND is
supported, it would be possible to migrate to it.

The driver-model rework changed, among other things, the way the private
data were moved around. It now uses the private field in the struct mmc.
However, the mmc_create argument was changed in the process to always pass
the array we used to have to store our private structures.
The basically means that all the MMC driver instances will now have the
private data of the first instance, which obviously doesn't work very well.
Pass the proper pointer to mmc_create.

Almost all of the newer Allwinner SoCs have a new operating mode for the
eMMC clocks that needs to be enabled in both the clock and the MMC
controller.
Details about that mode are sparse, and the name itself (new mode vs old
mode) doesn't give much details, but it seems that the it changes the
sampling of the MMC clock. One side effect is also that it divides the
parent clock rate by 2.

Before commit 26d6119 (fdt: Move fdt_fixup_ethernet to a common place)
the fdt_fixup_ethernet(...) was called during do_bootvx_fdt(...).
Afterwards the only (common) place for this fixup is during
image_setup_libfdt(...) and this is only called, at least on ARM
platform, from image_setup_linux(...).
All this ends up in the fact, that the fdt_fixup_ethernet(...) is only
called on booting a linux image and not on booting a vxWorks image.
We fix this with adding the fdt_fixup_ethernet(...) call again to

At present the NVMe uclass driver uses a global variable nvme_info
to store global information like namespace id, and NVMe controller
driver's priv struct has a blk_dev_start that is used to calculate
the namespace id based on the global information from nvme_info.
This is not a good design in the DM world and can be replaced with
the following changes:
- Encode the namespace id in the NVMe block device name during
the NVMe uclass post probe
- Extract the namespace id from the device name during the NVMe
block device probe
- Let BLK uclass calculate the devnum for us by passing -1 to
blk_create_devicef() as the devnum
