The Kernel pin definitions are more complete and up to date. Being
here we also use seperate files for the iomuxer like the other
i.MX SoCs already do.

The fec network interface initialization depends on the initialization of the
PMIC. Once the MC34704 driver is registered we can enable the PHY power supply,
and go on with the PHY initialization.
While we are at it convert the hard-coded GPIO registers access to the general
GPIO API for shorter and clearer code.

The kernel for the imx35 pdk doesn't do any detection for board and chip revision. This patch passes the info to the kernel so that v2 boards/chips boot properly.
imx35pdk: make COMPARE pad a GPIO1_5 output
This pad is an interrupt source, active low for one of the external ICs.

Newer Freescale 3-Stack development systems are equipped
with 64MiB of DDR2 SDRAM, instead of the 128MiB of mDDR SDRAM
with which earlier versions were shipped.

The PLL setup occasionally fails when the setup code runs
from SDRAM, so copy a little assembler helper function to
SRAM and execute it there.

Previous code ran the edb9302(a) boards with the PLL same settings as the
edb9301, at 166MHz core and 66MHz system bus clock. In difference to the edb9301
board the edb9302(a) is equipped with an EP9302 processor, which can be clocked
at higher rates than the EP9301. Therefore we can configure the edb9302(a) with
the same PLL settings as the other non-edb9301 boards, namely at 200MHz for
the core and 100MHz for the system bus clock.

edb93xx: The purpose of early_udelay() is to provide delay functionality in the
early board setup, when the stack isn't set up yet. With some compiler versions
the current implementation makes use of the stack and ends up crashing. Fix this
by removing an explicit division from early_udelay()
