ARM: davinci: create new common platform header for davinci Remove individual platform header files for dm365, dm355, dm644x and dm646x and consolidate it into a single and common header file davinci.h placed in arch/arm/mach-davinci. This reduces the pollution in the include/mach and is consistent with Russell's suggestions as part of his "pet peaves" mail. (See #4 in: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071516.html) While at it, fix the forward declaration of spi_board_info, and include the right header file instead. The further patches in the series take advantage of this consolidation for easy implementation of IO_ADDRESS elimination.

ARM: davinci: streamline sysmod access There are instances of IO_ADDRESS() being used for system module (sysmod) register access. Eliminate this in favor of a ioremap() based access. ioremap() the entire sysmod address space once during boot-up and provide a helper macro to access specific register offsets within the address space. With this, also eliminate ioremap() of specific sysmodule registers related to VPIF happening in DM646x EVM code. While at it, also eliminate some duplicate sysmod register offset macros defined in code and place offset definitions at one place in davinci.h Signed-off-by: Manjunath Hadli <manjunath.hadli@ti.com> Acked-by: Arnd Bergmann <arnd@arndb.de> [nsekhar@ti.com: removed the addition of ifndef __ASSEMBLER__ in davinci.h, eliminate IO_ADDRESS() usage left out in dm646x.c, cleanup VPIF sysmodule register access as part of this patch and keep all sysmod offsets in davinci.h Also, convert the WARN_ON() on failure to setup sysmod base to BUG_ON()] Signed-off-by: Sekhar Nori <nsekhar@ti.com>
