OFW needs to ignore speed setting on XO-4

Description

Due to problems with reliable wakeup from suspend, we have been cleared by Marvell to run all PXA2128 (MMP3) CPUs at 1.2GHz, regardless of the SoC specification.

We need the next release of OFW to ignore the speed setting jumper on the motherboard, and instead operate all PJ4 CPUs at 1.2 GHz (set_frequency_1.2g).

It is fine if the banner reflects the actual operating frequency (now always 1.2 GHz) instead of the expected CPU frequency for that SKU.

Probably should change trac to default the ownership of OFW bugs to James ...

  • next_action changed from code to test in build

Changed trac default ownership to Quozl for ofw - open firmware.

Banner deduces speed from registers, not from jumper, so no change required there.

Change made in CForth: 1c6dcd2.

Test build: http://dev.laptop.org/~quozl/q7b29jg.rom

Tested on SKU292, SKU293, SKU296.
