2018-12-04ARM: dts: meson: group the Cortex-A5 / Cortex-A9 peripheralsMartin Blumenstingl3-18/+30
The public Meson8b (S805) datasheet describes a memory region called "A9 Periph base" which starts at 0xC4300000 and ends at 0xC430FFFF. Add a simple-bus node and move all peripherals that are part of this memory region. This makes the .dts a bit easier to read. No functional changes.

2018-12-04ARM: 8816/1: dma-mapping: fix potential uninitialized returnNathan Jones1-1/+1
While trying to use the dma_mmap_*() interface, it was noticed that this interface returns strange values when passed an incorrect length. If neither of the if() statements fire then the return value is uninitialized. In the worst case it returns 0 which means the caller will think the function succeeded.

2018-12-04ARM: 8815/1: V7M: align v7m_dma_inv_range() with v7 counterpartVladimir Murzin1-5/+9
Chris has discovered and reported that v7_dma_inv_range() may corrupt memory if address range is not aligned to cache line size. Since the whole cache-v7m.S was lifted form cache-v7.S the same observation applies to v7m_dma_inv_range(). So the fix just mirrors what has been done for v7 with a little specific of M-class.

2018-12-04ARM: 8814/1: mm: improve/fix ARM v7_dma_inv_range() unaligned address handlingChris Cole1-3/+5
This patch addresses possible memory corruption when v7_dma_inv_range(start_address, end_address) address parameters are not aligned to whole cache lines. This function issues "invalidate" cache management operations to all cache lines from start_address (inclusive) to end_address (exclusive). When start_address and/or end_address are not aligned, the start and/or end cache lines are first issued "clean & invalidate" operation. The assumption is this is done to ensure that any dirty data addresses outside the address range (but part of the first or last cache lines) are cleaned/flushed so that data is not lost, which could happen if just an invalidate is issued. The problem is that these first/last partial cache lines are issued "clean & invalidate" and then "invalidate". This second "invalidate" is not required and worse can cause "lost" writes to addresses outside the address range but part of the cache line. If another component writes to its part of the cache line between the "clean & invalidate" and "invalidate" operations, the write can get lost. This fix is to remove the extra "invalidate" operation when unaligned addressed are used. A kernel module is available that has a stress test to reproduce the issue and a unit test of the updated v7_dma_inv_range(). It can be downloaded from http://ftp.sageembedded.com/outgoing/linux/cache-test-20181107.tgz. v7_dma_inv_range() is call by dmac_[un]map_area(addr, len, direction) when the direction is DMA_FROM_DEVICE. One can (I believe) successfully argue that DMA from a device to main memory should use buffers aligned to cache line size, because the "clean & invalidate" might overwrite data that the device just wrote using DMA. But if a driver does use unaligned buffers, at least this fix will prevent memory corruption outside the buffer.
