ARM: dts: bcm2835-rpi: re-enable booting from SD card ...

Kernel commit a19adf8 [0] changed the
RPi1 device tree from &sdhci to &sdhost, which was imported in barebox
commit d14b844. It seems that barebox
does not have a driver for brcm,bcm2835-sdhost (yet), which resulted in
barebox unable to boot from SD card. However, the driver for
brcm,bcm2835-sdhci worked fine in the past.

Although the upstream change was made for good reasons, the simplest
change for barebox for now is to revert to using &sdhci and disable
&sdhost.

Thanks to Alexander Dahl for raising this issue on the DistroKit
mailing list!

Because our SPI NOR flashes are too small, we require a root filesystem

ARM: boards: phytec-som-am335x: Add unified MLO ...

PCM-060 modules only have one-bank RAMs populated, which allows us to
find out the populated RAM size at run-time.

Therefore, a new entry point was create 'PHYTEC_ENTRY_UNIFIED_MLO'. This
creates a MLO for all modules of one family and all existing PCM-060
MLOs were replaced with this new entry point. To provide backward
compatibility for older modules, these were not affected.

In the first step generic RAM timings for the module family get loaded,
because RAM accesses are only possible with an initialized controller.
After that, the RAM size will be calculated and the RAM controller gets
reinitialized with the correct RAM timings.

This property is already documented in the bindings and supported by

didn't force this to low (which is the default for e.g. i.MX6), add the
property to barebox' imx25.dtsi to keep existing behaviour. If on a
board the OC pin is active low, you need to add

	/delete-property/ over-current-active-high;

in the board.dts.

If the zImage has a padding, which is less than 40 bytes
(sizeof struct fdt_header) the amount of read bytes would be propagated
as an error code. Fix this by only propagating real errors and treating
failure to read less than the expected amount as no concatenated DT
being present.

ARM: i.MX6ul: Add SoC specific lowlevel_init function ...

On i.MX6ul(l) (Cortex A7) We have to set the SMP bit before
enabling the caches, otherwise they won't work. Add a SoC specific
lowlevel_init function to be called by the i.MX6ul(l) boards.

Since this is a quirk of the Cortex A7 core we put the functionality
into a separate function to be reused by other Cortex A7 cores.

Change existing i.MX6ul(l) boards to use the new initialisation
function. It seems this is only needed when booting from USB,
in other boot modes the ROM will already have done the initialisation.
