Fix loop bailout off-by-one bugs reported by Juha Leppänen <juha_motorsportcom@luukku.com>. This second version incorporates comments from Russell King <linux@arm.linux.org.uk>. A new macro, 'omap_test_timeout', has been created, with cleaner code, and existing code has been converted to use it.

The code that reprograms the SDRC memory controller during CORE DVFS, mach-omap2/sram34xx.S:omap3_sram_configure_core_dpll(), does not ensure that all L3 initiators are prevented from accessing the SDRAM before modifying the SDRC AC timing and MR registers. This can cause memory to be corrupted or cause the SDRC to enter an unpredictable state. This patch places that code behind a Kconfig option, CONFIG_OMAP3_SDRC_AC_TIMING for now, and adds a note explaining what is going on. Ideally the code can be added back in once supporting code is present to ensure that other initiators aren't touching the SDRAM. At the very least, these registers should be reprogrammable during kernel init to deal with buggy bootloaders. Users who know that all other system initiators will not be touching the SDRAM can also re-enable this Kconfig option. This is a modification of a patch originally written by Rajendra Nayak <rnayak@ti.com> (the original is at http://patchwork.kernel.org/patch/51927/). Rather than removing the code completely, this patch just comments it out. Thanks to Benoît Cousson <b-cousson@ti.com> and Christophe Sucur <c-sucur@ti.com> for explaining the technical basis for this and for explaining what can be done to make this path work in future code. Thanks to Richard Woodruff <r-woodruff2@ti.com>, Nishanth Menon <nm@ti.com>, and Olof Johansson <olof@lixom.net> for their comments.

Avoid cluttering the Kconfig space with debug options that are rarely used. These can now be enabled and disabled by patching the "#undef DEBUG" in the source files with "#define DEBUG", conforming to the practice for the rest of the linux-omap code. Also, while we're here, some lines in plat-omap/Kconfig use sets of leading spaces when those lines should start with tabs. Convert most of them to use tabs.

mach-omap1/clock.c:omap1_clk_disable_unused() contains a test that assumes that the clock structures are available in the file's namespace. After a following patch, this will no longer be the case. So we need to reimplement that test. It turns out that we already have a facility in the clock framework to handle this case - the ENABLE_ON_INIT flag - used on OMAP2/3. Remove the offending test and mark the clocks that it was intended to catch as ENABLE_ON_INIT. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

cpu_mask is reused in the OMAP2xxx clock code to match against both the CPU-specific rate flags (e.g., RATE_IN_2420) and the OMAP clkdev integration code CPU flags (e.g., CK_242X). This means that any patch that renumbers the CK_* macros, as the next patch does, will probably break. This patch separates the clkdev_omap and clksel_rate CPU type detection flags so the CK_* macros can be renumbered freely. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Similar to the previous patch, the APLL code relied on the presence of the static struct clks in its own namespace. The APLL code didn't use them for validation, however - it adjusted its own internal state depending on the struct clk * that called it. Now that static struct clks are leaving the clock24xx.c namespace, use a more durable method: split the omap2_clk_fixed_enable() function into omap2_clk_apll96_enable() and omap2_clk_apll54_enable(). They still share a disable function. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Some parts of the clock code took advantage of the fact that the statically allocated clock tree was in clock{,24xx,34xx}.c's local namespace to do some extra argument checks. These are overzealous and are more difficult to maintain when the clock tree is in a separate namespace, so, remove them. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

VRFB rotation engine is a block in OMAP2/3 that offers 12 independent contexts that can be used for framebuffer rotation. Each context has a backend area of real memory, where it stores the pixels in undisclosed format. This memory is offered to users via 4 virtual memory areas, which see the same memory area in different rotation angles (0, 90, 180 and 270 degrees).

Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used to allocate large continuous blocks of SDRAM or SRAM. The features VRAM manager has that are missing from dma_alloc_* functions are: - Support for OMAP2's SRAM - Allocate without ioremapping - Allocate at defined physical addresses - Allows larger VRAM area and larger allocations The upcoming DSS2 uses VRAM manager. VRAM area size can be defined in kernel config, board file or with kernel boot parameters. Board file definition overrides kernel config, and boot parameter overrides kernel config and board file.
