We have the timer code in arch/arm/cpu/armv7/omap-common/timer.c that
has been configuring and enabling the timer, so remove our code that
does the same thing by different methods.
Tested on EVM GP, SK-EVM and Beaglebone.

AM/DM37x SoCs add the CTRL_WKUP_CTRL register. It contains the

of gpio_126, gpio_127 and gpio_129.

The computation was not correct with low clock values: setting a 1MHz
clock would result in an overlap that would then configure a 25Mhz
clock.
This patch implements a correct computation method according to the
kirkwood functionnal spec. table 600 (Serial Memory Interface
Configuration Register).

Define ARCH_MXC for i.MX devices. This is useful to identify features or

The i.MX28 is omitted because its architecture is a bit different (like imx/mxc
vs. mxs in Linux).

Allow usage of the imx-common/iomux-v3.h framework by including pad settings
for the i.MX51. The content of the file is taken from Linux kernel at
commit 5d23b39 plus the required changes to make it work in U-Boot.
The contained pad settings are the minimum required to make an Efika MX boot
and get all the currently-implemented peripherals working in U-Boot.
It is recommended that this file not be just a dumping ground for pins but
only contain the settings required for all the boards using it.
Changes for v2:
* reference commit id from Linux kernel
* additionally roll in the USB pads
* removed GPIO_NUMBER define

The SPL doesn't need the CP15 reconfiguration, as that's what the
BootROM does for us already. Moreover, when the CP15 is reconfigured
and the code returns control to BootROM, the USB boot works no more.
