Erik Gilling
konkers at android.com
Mon Jun 14 17:10:17 EDT 2010
v2: Fixes from Mike Rapoport
- remove unused header files (mach/dma.h and mach/nand.h)
- remove tegra 1 references from Makefile.boot
v2: fixes from Russell King
- remove mach/io.h include from mach/iomap.h
- fix whitespace in Kconfig
v2: from Colin Cross
- fix invalid immediate in debug-macro.S
v3:
- allow selection of multiple boards
