Using an MTD device (resp. partition) name in mtdparts is simple and
straightforward. However, for a long time already, another name was
given in mtdparts to indicate a device (resp. partition) so the
"mtdids" environment variable was created to do the match.
Let's create a function that, from an MTD device (resp. partition)
name, search for the equivalent name in the "mtdparts" environment
variable thanks to the "mtdids" string.

The current parser is very specific to U-Boot mtdparts implementation.
It does not use MTD structures like mtd_info and mtd_partition. Copy
and adapt the current parser in drivers/mtd/mtd-uclass.c (to not break
the current use of mtdparts.c itself) and write some kind of a wrapper
around the current implementation to allow other commands to benefit
from this parsing in a user-friendly way.
This new function will allocate an mtd_partition array for each
successful call. This array must be freed after use by the caller.
The given 'mtdparts' buffer pointer will be moved forward to the next
MTD device (if any, it will point towards a '\0' character otherwise).

It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.
The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.

hung the controller, while reducing it to 16MHz worked just fine

While trying to enable the dw_mmc on rk3188 I managed to confuse
and hang the dw_mmc controller into not delivering further data.
The fifo state never became ready and the driver was iterating in
the while loop reading 0-byte packets forever.
So inspired by how other implementations handle this, check the fifo-
state beforhand and add a timeout to catch any glaring fifo issues
without hanging uboot altogether.

[ commit 9564a8cf422d7b58f6e857e3546d346fa970191e in Linux ]
I tried building using a freshly built Make (4.2.1-69-g8a731d1), but
already the objtool build broke with
orc_dump.c: In function ‘orc_dump’:
orc_dump.c:106:2: error: ‘elf_getshnum’ is deprecated [-Werror=deprecated-declarations]
if (elf_getshdrnum(elf, &nr_sections)) {
Turns out that with that new Make, the backslash was not removed, so cpp
didn't see a #include directive, grep found nothing, and
-DLIBELF_USE_DEPRECATED was wrongly put in CFLAGS.
Now, that new Make behaviour is documented in their NEWS file:
* WARNING: Backward-incompatibility!
Number signs (#) appearing inside a macro reference or function invocation
no longer introduce comments and should not be escaped with backslashes:
thus a call such as:
foo := $(shell echo '#')
is legal. Previously the number sign needed to be escaped, for example:
foo := $(shell echo '\#')
Now this latter will resolve to "\#". If you want to write makefiles
portable to both versions, assign the number sign to a variable:
C := \#
foo := $(shell echo '$C')
This was claimed to be fixed in 3.81, but wasn't, for some reason.
To detect this change search for 'nocomment' in the .FEATURES variable.
This also fixes up the two make-cmd instances to replace # with $(pound)
rather than with \#. There might very well be other places that need
similar fixup in preparation for whatever future Make release contains
the above change, but at least this builds an x86_64 defconfig with the
new make.

Something has changed in the last several month such that when buildman
builds U-Boot incrementally and a new CONFIG option has been added to the
Kconfig, the build hanges waiting for input:
Test new config (NEW_CONFIG) [N/y/?] (NEW)
Since binamn does not connect the build's stdin to anything this waits on
stdin to the build thread, which never comes. Eventually I suspect all the
threads end up in this state and the build does not progress.
Fix this by passing /dev/null as input to the build. That way, if there is
a new CONFIG, the build will stop (and fail):
Test new config (NEW_CONFIG) [N/y/?] (NEW)

Since there is no canonical "board device" that can be used in board
files, it is difficult to use DM function for board initialization in
these cases.
Hence, add a uclass that implements a simple "board device", which can
hold devices not suitable anywhere else in the device tree, and is also
able to read encoded information, e.g. hard-wired GPIOs on a GPIO
expander, read-only memory ICs, etc. that carry information about the
hardware.
The devices of this uclass expose methods to read generic data types
(integers, strings, booleans) to encode the information provided by the
hardware.
