[PATCHv2 0/2] uio:powerpc:mpc85xx: l2-cache-sram uio driver

[Wang Wenhu]

This series try to push an uio driver which works on freescale mpc85xx
to configure its l2-cache-sram as a block of SRAM and enable user level
application access of the SRAM.

1/2: For coding-style consideration of macro CONFIG_HAVE_IOREMAP_PORT;
2/2: Implementation of the uio driver.

This is the second version, which addressed some commets:
1. Use __be32 instead of u32 for the big-endian data declarations;
2. Remove "static inline" version of generic_access_phys definition in .h file
and give a version of no-op definition in mm/memory.c;
3. Use generic ioremap_cache instead of ioremap_coherent

For v1, see:

2/2: https://lore.kernel.org/lkml/YqHy1uXwCLlJmftr@kroah.com/
