[PATCH 3/8] pl080.h: moved from arm/include/asm/hardware to include/linux/amba/

Davide Ciminaghi ciminaghi at gnudd.com
Fri Nov 23 10:08:25 EST 2012


From: Alessandro Rubini <rubini at gnudd.com>

The header is used by drivers/dma/amba-pl08x.c, which can be compiled
under x86, where PL080 exists under a PCI-to-AMBA bridge. This patche
moves it where it can be accessed by other architectures, and fixes
all users.
