2012-09-23mx51evk: Add CONFIG_REVISION_TAGBenoît Thébaudeau
FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information. If this data is not present, the kernel misconfigures the TZIC, which results in the timer interrupt handler never being called, so the kernel deadlocks while calibrating its delay.

2012-09-17MX6: drop binary constants from iomux headerStefano Babic
Constants set with binary value (0b...) are not compiled from old toolchain when used by the clrsetbits_le32 macro. Replaces them with the corresponding hex value. The error reported (for example with the mx6qsabrelite board) is something like: mx6qsabrelite.c:369:1: error: invalid suffix "b101" on integer constant mx6qsabrelite.c:369:1: error: invalid suffix "b10010" on integer constant mx6qsabrelite.c:369:1: error: invalid suffix "b0000" on integer constant mx6qsabrelite.c:369:1: error: invalid suffix "b10001" on integer constant Signed-off-by: Stefano Babic <sbabic@denx.de>
2012-09-10MX: set a common place to share code for Freescale i.MXStefano Babic
Up now only MX5 and MX6 can share code, because they have a common source directory in cpu/armv7. Other not armv7 i.MX can profit of the same shared code. Move these files into a directory accessible for all, similar to plat-mxc in linux. Signed-off-by: Stefano Babic <sbabic@denx.de>

2012-09-03kw_spi: fix clock prescaler computationValentin Longchamp
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.

Allow usage of the imx-common/iomux-v3.h framework by including pad settings for the i.MX51.

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.
