* Tegra: Change Tegra20 to Tegra in common code, prep for T30Tom Warren2012-09-10-43/+171
| | | | | | | | | | Convert TEGRA20_ defines to either TEGRA_ or NV_PA_ where appropriate. Convert tegra20_ source file and function names to tegra_, also. Upcoming Tegra30 port will use common code/defines/names where possible. Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Stephen Warren <swarren@nvidia.com>

| * am33xx: Remove redundant timer configTom Rini2012-09-04-20/+0
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | AM/DM37x SoCs add the CTRL_WKUP_CTRL register.

* kw_spi: fix clock prescaler computationValentin Longchamp2012-09-03-0/+1
| | | | | | | | | | | | | | | | | 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 behaviors common to all i.MX SoCs. 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.
