Just curious, from Russell's replying for patch 0005, IIUC we cannot totally remove usage of amba_request_regions() and amba_release_regions(), there have some coner case should use amba_request_regions() + ioremap(). Does it make sense to remove most usage of amba_request_regions() and amba_release_regions() but we still keep these two functions in the kernel? Thanks, Leo Yan
