Zylonite needs 32, ASIC3 based boards need 70. My problem is still that due to the way IRQ_GPIO is hardcoded, ASIC3 based boards need 70 IRQs starting at IRQ_BOARD_START. If I define ASIC3 IRQs similar to LoCoMo or SA1111, things break as soon as something selects PXA_HAVE_BOARD_IRQS. Increasing the default number of board IRQs to 70 instead doesn't seem very nice.

If not, it will be assumed for now that frequency change will work without voltage control. This assumes that the IPL/SPL installs sane values to an existing voltage regulator (ie. voltage high enough to support the full range).
