After Reset VMMC goes to default VSEL. This is not a clean power cycle for
some SD cards.
Set flag WR_S for VMMC to avoid going to default VSEL.

when doing bootm -v -v we dumped the original tree to the console.
Make sure to print the fixed tree instead so that the fixups can

This is a port of the official PLL errata workaround from Freescale.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.
This is based on U-Boot commit:

This chipselect is used on RDK Zigbee connector. Since we cannot
define additional chipselect after SPI is initialized, define this one
in main SPI initialization in PCM038 SOM.

On ARM the boarddirs are only cleaned due to the regular file
pattern search, but are not explicitly cleaned. This makes
it impossible to clean files which are not matched by a pattern
but have to be explicitly cleaned due to adding them to extra-y.
This patch changes the board-/board-y variables to += so that
we can use $(board-) to add it to common-. This way the board
directories are also cleaned.
While touching the board-y variables anyway order them
alphabetically.

Add a command to generate the zynq image instead of generating it

The pbl used 'zbarebox.bin' as target instead of the real file. This
lead to strange effects that the images depending on zbarebox.bin were
only built every second time. This uses the full path as target.

The mc13892 driver knows that it needs spi-cs-high, so the mc13892
will work. The dataflash also connected to this bus though can only
be probed when the mc13892 is inactive. Due to driver probe differences
we can only make sure the mc13892 is inactive when we put the information
into the devicetree.

The boot source for the i.MX23 is configured via a few GPIOs, which are later
be used for different purposes (like LCD data for example). The SoC internal
ROM reads these GPIOs and uses the selected boot source.
For various reasons the boot source is also of interest when Barebox is running.
This detection approach reads again the GPIOs. It switches temporarily the pins
to act as GPIOs and input, reads their settings, and switches back to their
previous functions.

At least the iMX6 boot rom seems to jump into barebox with a non
invalidated d-cache which causes data corruption when
v7_mmu_cache_flush() executed by arm_early_mmu_cache_flush() overrides
stack or other valid data.
That's why the cache must be invalided for this processors explicitly
(e.g. in barebox_arm_reset_vector()). Operation differs from flush only
in one instruction so that patch modifies the existing
v7_mmu_cache_flush() function slightly by adding an optional argument.
