Messages in this thread Patch in this message |  | | From | Alexey Brodkin <> | Subject | [PATCH] drivers/block/xsysace - replace in(out)_8/in(out)_be16/in(out)_le16 with generic iowrite(read)8/16(be) | Date | Tue, 29 Jan 2013 20:02:59 +0400 |

in(out)_8/in(out)_be16/in(out)_le16 are very powerpc/microblaze specific. To enable use of Xilinx System ACE driver build for other architectures (for example it's possible to use it on Xilinx ml-509 board with ARC700 in FPGA) we need to use generic implementation of accessors.
Current implementation was successfully built with Sourcery G++ Lite 2011.03-39 for Power EABI (ppc44x_defconfig).
