[PATCH v3 00/13] OMAP: DMA: hwmod and DMA as platform device

[manjugk@ti.com (G, Manjunath Kondaiah)]

This patch series converts DMA library into platform device and hwmod 
adaptation is done for omap2+ processors.

It also replaces cpu_*is* checks by moving omap1 and omap2+ processor 
code into repsective mach-omapx directories. The common code in plat-omap
will use device attributes for differentiating omap1 and omap2 code.

Build Report:
omap1:  Success for omap_h2_1610_defconfig
omap2+: Success for omap2plus_defconfig

Test Report:
omap2+:(multiboot defconfig boots on all the omap2+ boards listed below):
OMAP4BLAZE: http://pastebin.com/HVnim30G
OMAP3630ZOOM3: http://pastebin.com/JJwrtP4F
OMAP243SDP: http://pastebin.com/mz7cVQL3

omap1 : Not tested 

Test cases executed:
1. All applicable TI DMA tests which are located at:
http://dev.omapzoom.org/?p=richo/device_driver_test.git;a=tree;f=dma/test_code;h=0d00de3c0fe6933b405c62da63f694883f3e4b8f;hb=2c50a5a58dea0ffc2d31b827935aeef9b9d11253

2. Use case tests :  TI MMC tests are executed with differenct types of
files systems such as DOS, ext2, ext3 etc on omap4 blaze and omap3630 zoom3.

v1:
These changes are based on comments received during internal discussions which has changes(compared to previous version) such as:
 - Code optimization
 - Patches are rearranged in more meaningful way so that git bisect works at any
   intermediate patch in the series.
 - Build tested for all omap's(OMAP1 and OMAP2PLUS)
 - Boot tested for OMAP3 and OMAP4(appreciate if some one tests on OMAP1/2)
 - Applicalbe tests are executed on OMAP3 and OMAP4 boards
 - Rebased and added descriptor autoloading feature(only for omap3630 and omap4)
