You're right - I got the IOMUX tables wrong and thought UART0 pins are
selected unconditionally. But as it turns out TXD1/RXD1 is for UART0
(mxc_uart_device0), TXD2/RXD2 for UART1 (mxc_uart_device1) etc.
Below is a new patch.

csi_clk parent was defined with ahb_clk. However, according to the
m31 reference manual, it should be serial_pll_clk.
Guennadi always used a 20 MHz clock that was by chance changed to
a 45 MHz that fits in the mt9t031 spec. Now the clocks are computed

This new implemenatation avoids that two physical pins are claimed by

The gpio kernel lib is also called when a capable gpio pin is assigned
its gpio function.
The mxc_iomux_mode function is still here for backward compatibility but
should not be used anymore.
V2:
In the precendent revision, the iomux code was claiming a pin when its
hardware mode was changed. This was uncorrect: when the hardware mode is
changed, the pin must still be claimed through the iomux.
In order to have a pin working in mode hw2, we must fist issue the
mxc_iomux_set_gpr call and then the corresponding mxc_iomux_mode calls
with the FUNC mode (usually done with mxc_iomux_setup_multiple_pins).

This patch converts the external "add_mx31lite-basic_defconfig.diff" to our
MXC implementation.
Note: This patch fixes a board reference only.

This patch adds basic support for i.MX31 LiteKit by LogicPD.
With printascii() in kernel/printk.c, it boots right into the
rootfs-panic.
Note: This is a modified version of Daniel's patch to fit into this patch
stack.

This patch adds timer support for the i.MX machine family. This code can
be used on the following machs:
- i.MX1 (tested)
- i.MX2 (i.MX21 (to be tested), i.MX27 (tested))
- i.MX3 (i.MX31 (tested))
TODO: It seems impossible to build a kernel for more than one CPU because the
timer do not follow the platform device rules. So it does only work if
timer 1 can be accessed on all CPUs at the same address.

This patch bases on the one from Daniel Mack. The most important change to
Daniel's patch is to be more generic. This gpio routine supports at least
the i.MX27 and i.MX31 processors.

Move the xtime write mode seqlock into timer_tick(), so it only
surrounds the call to do_timer().
This avoids a deadlock in update_process_times() ...
hrtimer_get_softirq_time() which tries to get a read mode seqlock
on xtime, thereby preventing booting.

This patch adds the foundation pieces for
the Freescale MXC platforms, including
i.MX2 and i.MX3 based systems.
The bare-bones MX31 support in this patch
boots to the rootdev panic with 8250 serial
console configured "console=ttyS0,115200".
It assumes that Redboot is the boot loader.
