Changing the arch/arm/dts/am335x-phytec-phycore.dts would be
another option but that would break loading a mainline kernel.
The idea/patch is coming from Jan.
phyFLEX boards beginning with 1362.2 have a workaround for this
i.MX6 bug:
ERR006282 ROM code uses nonreset PFDs to generate clocks, which may
lead to random boot failures
On these boards the SD4_DAT3 pin os connected to the CMIC. The CMIC
will reset the board after 10s when the pin isn't toggled.

The rule in barebox is to name the directories after
the modules. As hummingboard is just one of the
carriers for the MicroSOM module, name the directory
accordingly.

Instead of repeating the same lowlevel init for every board
move it to it's own initcall.
Avoids code bloat and shaves off almost 1.5kB of uncompressed
barebox size for a default imx_v7_defconfig build.
For boards wherethe hostname setup was done in the postcore
initcall we move this to a device initcall to get it out of
the way.
