If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by:

Strictly speaking this call is a no-op on the platform where dcscb.c is used since it only has architected caches. The call was there as a hint to people inspired by this code when writing their own backend, but the hint might not always be correct. For example, if a PL310 were to be used it wouldn't be safe to call the regular outer_flush_all() as atomic instructions for locking are involved in that case and those instructions cannot be assumed to still be operational after v7_exit_coherency_flush() has returned. Given no other CPUs (in the cluster) should be running at that point then standard concurrency concerns wouldn't apply. So let's simply kill this call for now and enhance the existing comment.

Export the DMA register information from the SoC specific data, such that we can access the registers directly in omap-dma.c, mapping the register region ourselves as well. Rather than calculating the DMA channel register in its entirety for each access, we pre-calculate an offset base address for the allocated DMA channel and then just use the appropriate register offset.

The omap_system_dma_plat_info structure is only seven words, it's not worth the expense of kmalloc()'ing backing store for this only to release it later. Note that platform_device_add_data() copies the data anyway. Clean up the initialisation of this structure - we don't even need code to initialise most of this structure. Acked-by:

This really needs to be there, because otherwise the plat-omap code can kfree() this data structure, and then re-use the pointer later. Acked-by:
