From d610f503612ddb5bf55e477fd48c678b3deab7ca Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Thu, 12 Mar 2015 20:32:42 +0800 Subject: sata_svw: remove the dependency on PPC_OF The OF functionality has moved to a common place and be used by many archs. So we don't need to include the ppc arch specific header files and depend on PPC_OF option any more. This is a preparation for killing PPC_OF.

These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.
