[PATCH v4 00/14] ARM: at91: skov-arm9cpu (SAM9263) first stage support

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

SDRAM setup and SD-Card chainloading support were previously added[1]
by Sam as well as a WIP patch to enable them for Skov ARM9CPU.

I reworked his final WIP patch and fixed some smaller and bigger issues
that I ran into. Now barebox can replace at91bootstrap on this platform
when booted from SD.

What didn't work for me were USB and Ethernet, but these didn't work in
Linux either when booted with the same device tree. I suspect this to be
related, but I don't have use for either USB or Ethernet in barebox at
this time, so I am happy with functional SD and nor flash.

v3 -> v4:
  - dropped final patch in v3 (15/15). The problem with the USB hang
    needs to be fixed some other way (Sascha)
  - used defines for PLLA_SETTINGS, PLLB_SETTINGS (Sam)
  - Added Sam's R-b
