ARM: OMAP2: Add common register access for 24xx and 34xx This patch adds common register access for 24xx and 34xx power and clock management in order to share code between 24xx and 34xx. Only change USB platform init code to use new register access, other access will be changed in later patches.

ARM: OMAP: Introduce omap_globals and prcm access functions for multi-omap New struct omap_globals contains the omap processor specific module bases. Use omap_globals to set the various base addresses to make detecting omap chip type simpler. Also introduce OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS for future multi-omap patches.

omap: Split OMAP2_IO_ADDRESS to L3 and L4 This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to reclaim more IO space. The omap_read*() and omap_write*() functions will work only over L4 address space. Current omap kernel stack uses these functions only to access registers over L4 io address space Note that these macros should only be used when ioremap does not work. Please use ioremap instead in all new code. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
