2011-11-13Add some missing endian conversions in fdt_support.cGabe Black
Some functions in fdt_support.c use fdt_getprop to read 32 bit values out of the device tree, but then use them directly without doing any endian conversion. Because they check for a value that doesn't actually appear in practice, the functions continued to work even though they're incorrect. This change adds the missing conversions.

2011-11-12Tegra2: mmc: Factor out mmc_wait_inhibit functionalityAnton staaf
This is a well encapsulated section of mmc_send_cmd, by moving it to it's own function it increases the readability of mmc_send_cmd.

2011-11-12Tegra2: mmc: Add data transfer completion timeoutAnton staaf
Currently when no expected completion condition occures in the mmc_send_cmd while loop that is waiting for a data transfer to complete the MMC driver just hangs. This patch adds an arbitrary 2 second timeout. If nothing we recognize occures within 2 seconds some diagnostic information is printed and we fail out.

2011-11-12Tegra2: mmc: Support DMA restarts at buffer boundariesAnton staaf
Currently if a DMA buffer straddles a buffer alignment boundary (512KiB) then the DMA engine will pause and generate a DMA interrupt. Since the DMA interrupt is not enabled it will hang the MMC driver. This patch adds support for restarting the DMA transfer. The SYSTEM_ADDRESS register contains the next address that would have been read/written when a boundary is hit. So we can read that and write it back. The write triggers the resumption of the transfer.

2011-11-11powerpc/mpc85xx: Set SYSCLK to the required frequencyJerry Huang
For ICS307-02, there is one general expression to generate SYSCLK: CLK1Frequency = InputFrequency * 2 * (VDW + 8) / ((RDW + 2) * OD) If we want the required frequency for SYSCLK, we must find one solution to generate this frequency, this solution includes VDW, RDW and OD. For OD, there are only eight option value: 10, 2, 8, 4, 5, 7, 3, 6. For RDW, the range is 1 to 127. For VDW, the range is 4 to 511. First, we use one OD, RDW and required SYSCLK to calculate the VDW, if VDW is in it's range, we will calculate the CLK1Frequency with the OD, RDW and VDW calculated, and we will check this percent (CLK1Frequency / required SYSCLK), and the precision is 1/1000. if the percent is less than 1/1000, we think the CLK1Frequency is we want. Otherwise, We will continue to calculate it with the next OD and RDW. Signed-off-by: Jerry Huang <Chang-Ming.Huang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2011-11-11iMX28: Fix ARM vector handlingMarek Vasut
This patch introduces proper ARM vector handling for i.MX28 CPU. This issue wasn't addressed because the interrupts weren't enabled on any ARMv5 core, therefore the issue wasn't noticed earlier. In previous implementation, the vectoring code used by i.MX28 CPU when an exception happened was that of the SPL. With this change, the branch target when an exception happens can be reconfigured by U-Boot.
