 tag cleanup-omap-tags-for-v3.7
 tagger Tony Lindgren <tony@atomide.com> 1347323254 -0700
 
 Remove the ancient omap specific atags that are no longer needed.
 
 At some point we were planning to pass the bootloader information
 with custom atags that did not work out too well.
 
 There's no need for these any longer as the kernel has been booting
 fine without them for quite some time. And Now we have device tree
 support that can be used instead.
