The cpu setup is now passed the cpu idcode and the table

As well as moving the cpu initialisation code, we move the

than pass this to iotable_init().
This patch does not rename any of the init functions that

Based on similar code from the tsx09 series of machines, just rips the MAC
address out of flash and stuffs it into the NIC. Tested on a DNS323 rev B1.
It's possible (though unlikely) that an A1 will have the MAC in a different

[ARM] pxa: add support for additional GPIOs on PXA26x
Original patch from Marek Vasut, the problems with PXA26x are:
1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
inverted in GPDR2, as well as their alternate function bits being
'1' for their GPIO functionality in GAFRx
2. there is no easy way to decide if the processor is a pxa26x or a
pxa250/pxa255 at run-time, so the assumption here is the pxa26x
will be treated as one of the pxa25x variants, and board code
should have a better knowledge of the processor it is featured
Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.
Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.
__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.
