[PATCH v3 3/3] arm: omap3: cm-t35: add support for cm-t3730

Igor Grinberg
2011-06-14T21:16:22Z

cm-t3730 is basically the same board as cm-t35,
but has AM/DM3730 SoC assembled and therefore some changes are required.

v3: fix MACH_* selection
remove completely the use of cpu_is_*
v2: Add debug uart entry
