[PATCH 11/11] ARM: nomadik: get rid of <mach/hardware.h>

Linus Walleij linus.walleij at linaro.org
Mon Jan 7 17:57:07 EST 2013


This was only used from the core machine, source it into the machine
file and delete, also convert all direct references using the
physical-to-virtual macros in this file to ioremap() and only
default-remap the 4K used by the debug UART.
