[PATCH 1/5] omap2: modify omap24xx.h to improve constant names and prepare for multi-arch kernels

[Paul Walmsley <paul@pwsan.com>]

[-- Attachment #1: 0001-omap2-modify-omap24xx.h-to-improve-constant-names-a.patch --]
[-- Type: text/plain, Size: 5013 bytes --]

Redo the defines in omap24xx.h to fix poorly-named defines, such as
OMAP24XX_SDRC_BASE, which is different between 2420 and 2430.  Also,
prepare for future multi-architecture kernels by removing the
architecture prefixes from several of the defines.  (Presumably in the
future these will be assigned to 'static void __iomem *'s by runtime
init code depending on the CPU type.)
