* sh: Move PMB debugfs entry initialization to later stagePawel Moll2010-03-04
| | | | | | | | | ... so the "sh_debugfs_root" is already available. Previously it wasn't and in result its path was "/sys/kernel/debug/pmb" instead of "/sys/kernel/debug/sh/pmb". Signed-off-by: Pawel Moll <pawel.moll@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up flush_cache_vmap() on SMP.Paul Mundt2010-03-04
| | | | | | | | flush_cache_all() uses broadcast IPIs, so we can't wrap in to that when IRQs are disabled. The local cache flush manages to do what we need here anyways, so just switch to that. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: fix up MMU reset with variable PMB mapping sizes.Paul Mundt2010-03-04
| | | | | | | | | | | | | | | Presently we run in to issues with the MMU resetting the CPU when variable sized mappings are employed. This takes a slightly more aggressive approach to keeping the TLB and cache state sane before establishing the mappings in order to cut down on races observed on SMP configurations. At the same time, we bump the VMA range up to the 0xb000...0xc000 range, as there still seems to be some undocumented behaviour in setting up variable mappings in the 0xa000...0xb000 range, resulting in reset by the TLB.

* sh: establish PMB mappings for NUMA nodes.Paul Mundt2010-03-02
| | | | | | | | In the case of NUMA emulation when in range PPNs are being used for secondary nodes, we need to make sure that the PMB has a mapping for it before setting up the pgdat. This prevents the MMU from resetting. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: check for existing mappings for bolted PMB entries.Paul Mundt2010-03-02
| | | | | | | | | When entries are being bolted unconditionally it's possible that the boot loader has established mappings that are within range that we don't want to clobber. Perform some basic validation to ensure that the new mapping is out of range before allowing the entry setup to take place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: fixed virt/phys mapping helpers for PMB.Paul Mundt2010-03-02
| | | | | | | | This moves the pmb_remap_caller() mapping logic out in to pmb_bolt_mapping(), which enables us to establish fixed mappings in places such as the NUMA code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: make pmb iomapping configurable.Paul Mundt2010-03-02

* sh: reworked dynamic PMB mapping.Paul Mundt2010-03-02
| | | | | | | | | This implements a fairly significant overhaul of the dynamic PMB mapping code. The primary change here is that the PMB gets its own VMA that follows the uncached mapping and we attempt to be a bit more intelligent with dynamic sizing, multi-entry mapping, and so forth.

This is not possible on the DM6467T EVM because of the presence of a 33MHz oscillator. The TSIF module also requires the CDCE949 to generate the data clocks. The actual clock definitions will be added by patches adding support for DM6467T VPIF and TSIF. This patch mearly lays the foundation for that work.

Testing: The various frequency outputs on Y1 have been tested using a out-of-tree VPIF video driver supporting HD video. The register values for Y5 frequency outputs have been derived from TSIF driver sources in MontaVista LSP kernel, but actual output has not been tested for lack of TSIF driver which actually works on the latest kernel.

The code depends on the the "deepsleep" feature to suspend the SoC and saves power by gating the input clock. The wakeup can be based on an external event as supported by the SoC. Assembly code (in sleep.S) is added to aid gating DDR2 clocks. Code doing this work should not be accessing DDR2. The assembly code is relocated to SRAM by the code in pm.c The support has been validated on DA850/OMAP-L138 only though the code is (hopefully) generic enough that other SoCs supporting deepsleep feature simply requires SoC specific code to start using this driver.

The new part supports 1080p video and has the ARM running at 495MHz. More SoC information: http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html Spectrum Digital, Inc has a new EVM for this part. It is _mostly_ same as the older DM6467 EVM except for a 33MHz crystal input and THS8200 video encoder for 1080p support. The meat of this patch is dedicated to initializing the crystal frequency from EVM board file. Additional notes: I did consider some alternative ways to make the crystal input board specific including - (1) having board code initialize the crystal frequency using the first member of soc_info->cpu_clks array (2) introducing a new ref_clk_rate member in soc_info structure. But, the current way seems to be the simplest and least intruding considering that both the clock array and SoC info structure are actually private to the SoC file. Also the fact that davinci_common_init() initializes both the soc_info and clocks in one go. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
