2010-10-29MIPS: Octeon: Probe for Octeon II CPUs.David Daney1-0/+7

The CN63XX is a new 6-CPU SOC based on the new OCTEON II CPU cores. Join some lines back together. This makes some of them exceed 80 columns, but they are uninteresting and this unclutters things.

2010-10-29MIPS: Octeon: Rewrite DMA mapping functions.David Daney6-301/+389
All Octeon chips can support more than 4GB of RAM. Also due to how Octeon PCI is setup, even some configurations with less than 4GB of RAM will have portions that are not accessible from 32-bit devices. Enable the swiotlb code to handle the cases where a device cannot directly do DMA. This is a complete rewrite of the Octeon DMA mapping code.

2010-10-29MIPS: Convert DMA to use dma-mapping-common.hDavid Daney8-153/+136
Use asm-generic/dma-mapping-common.h to handle all DMA mapping operations and establish a default get_dma_ops() that forwards all operations to the existing code. Augment dev_archdata to carry a pointer to the struct dma_map_ops, allowing DMA operations to be overridden on a per device basis. Currently this is never filled in, so the default dma_map_ops are used. A follow-on patch sets this for Octeon PCI devices. Also initialize the dma_debug system as it is now used if it is configured.

2010-10-29MIPS: Get rid of branches to .subsections.Ralf Baechle5-297/+243
It was a nice optimization - on paper at least. In practice it results in branches that may exceed the maximum legal range for a branch. We can fight that problem with -ffunction-sections but -ffunction-sections again is incompatible with -pg used by the function tracer. By rewriting the loop around all simple LL/SC blocks to C we reduce the amount of inline assembler and at the same time allow GCC to often fill the branch delay slots with something sensible or whatever else clever optimization it may have up in its sleeve. With this optimization gone we also no longer need -ffunction-sections, so drop it. This optimization was originally introduced in 2.6.21, commit 5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp. f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f (kernel.org).

Fix kprobes after git commit 1e54622e0403891b10f2105663e0f9dd595a1f17 broke it. The kprobe_handler is now called with interrupts in the state at the time of the breakpoint. The single step of the replaced instruction is done with interrupts off which makes it necessary to enable and disable the interupts in the kprobes code.

2010-10-28x86, memblock: Fix early_node_mem with big reserved region.Yinghai Lu1-5/+2
Xen can reserve huge amounts of memory for pre-ballooning, but that still shows as RAM in the e820 memory map. early_node_mem could not find range because of start/end adjusting, and will go through the fallback path. However, the fallback patch is still using memblock_x86_find_range_node(), and it is partially top-down because it go through active_range entries from low to high. Let's use memblock_find_in_range instead memblock_x86_find_range_node. So get real top down in fallback path. We may still need to make memblock_x86_find_range_node to do overall top_down work.

Adding card detect callback function and card detect configuration function for MMC1 Controller on OMAP4. Card detect configuration function does initial configuration of the MMC Control & PullUp-PullDown registers of Phoenix. For MMC1 Controller, card detect interrupt source is twl6030 which is non-gpio. The card detect call back function provides card present/absent status by reading MMC Control register present on twl6030. Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect, the suspend/resume initialization which was done in omap_hsmmc_gpio_init previously is moved to the probe thus making it generic for both OMAP3 & OMAP4.

On AP4EVB the card detect pin of the top SD/MMC slot is not directly connected to the tmio/mmcif controller but to a GPIO pin, so polling needs to be done for SDHI1 and MMCIF in order to support hotplug for that slot. SHDI1 and MMCIF share that slot, and the used controller is selected by a DIP switch. This patch adds a helper function to check if a card is present in that particular slot, registers this function with SDHI1 and MMCIF and enables polling for SDHI1.
