2013-02-04ppc: arm: Move sdhc_clk into arch_global_dataSimon Glass
This is used by both powerpc and arm, but I think it still qualifies as architecture-specific. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-03ARM: add wfi assembly macroRob Herring
Since wfi instruction is only available on ARMv7, add a conditional macro for it. Signed-off-by: Rob Herring <rob.herring@calxeda.com>

2013-02-01Add architecture-specific global dataSimon Glass
We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-01-28mxs: dma: Fix APBH DMA driver for MX23Marek Vasut
The MX23 has less channels for the APBH DMA, sligtly different register layout and some bits in those registers are placed differently. Reflect this in the driver.

2013-01-21mxs: ssp: Pull out the SSP bus to regs conversionMarek Vasut
Create function which converts SSP bus number to SSP register pointer. This functionality is reimplemented multiple times in the code, thus make one common implementation. Moreover, make it a switch(), since the SSP ports are not mapped in such nice linear fashion on MX23, therefore having it a switch will simplify things there.

2013-01-16Tegra30: fdt: Update DT files with I2C info for T30/CardhuTom Warren
Note that T30 does not have a separate/different DVC (power I2C) controller like T20 - all 5 I2C controllers are identical, but DVC_I2C is still used to designate the controller intended for power control (PWR_I2C in the schematics). On Cardhu, it's used to access the PMU and EEPROM, as well as the audio codec, temp sensor, and fuel gauge devices from the OS. Signed-off-by: Tom Warren <twarren@nvidia.com>

2013-01-14pxa: Save lr register in relocate_code functionŁukasz Dałek
When u-boot is compiled for PXA25x processor, pxa/start.S is calling cpu_init_crit by BL instruction. BL is overwriting lr register so relocate_code is going into infinite loop.
