Xtensa improvements for v4.19:
- switch xtensa arch to the generic noncoherent direct mapping operations; - add support for DMA_ATTR_NO_KERNEL_MAPPING attribute; - clean up users of platform/hardware.h in generic Xtensa code; - fix assembly cache maintenance code for long cache lines; - rework noMMU cache attributes initialization; - add big-endian HiFi2 test_kc705_be CPU variant. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEK2eFS5jlMn3N6xfYUfnMkfg/oEQFAlt7KZATHGpjbXZia2Jj QGdtYWlsLmNvbQAKCRBR+cyR+D+gRKZyD/9hJ9L4qNa+E1UaEGxuLcQP98HtwXDV 140/v8m6pw3leblyIGiFypnjHZidol74YQ17DDzckEuSZLa13H8EcB1c/oNTjKve 65/Jz8M9KPaASIRgdcqMp7IZt4wGSVV4mOkwodtmJBefpQa6Y2gHXhmLiIK27WVR m/J6xVYCgTa93e+Tjcn1x+Y1NbpzFlRV2MTfMZLD8hxtUYmt+iPPUtWMKjn3bBJI ps0cor1yAvbGQ6Bg95yal/Wd6pHfnqMs3is3BqW4ZC0LYwch+JT5Btbh2SVYOrX+ ea7iAy3f8eH866SAGb4B3JOTwtaSFL84QFVp/UXY0tZk2IDr3YGiBOV2pic2zSao 3td3y/ZTROcW+18gUip5VtaSKbVZ1yWbut9MnbW2i79VoXAx3XwA4Mo9cBYTQUaj rAB/B62ACcQt0OUG4jvamGdmIgF+FF6Pr4nqJ9iFfIoj4e+UxUMH9U2Wd8H/7WCl rWYJEIkGE8z7bkQw2izXfVc3wBSc2c6z3UjEMijU8I7/V3Yg+WKcAgaWsHd34IDS bURrTWqPN4plXbuuQHrRinHlFUjsx6iZk3ClXn7NTFPx2G69aPOoiHxz0tV9C9Tp fwRHMy5wTeKjfbz4Gd2LlHjDz6kO53DVOsb09B12lVPPTvtLOLbI0G4gHzOw3QVk WwxmbsAv1/NaLA== =osJd -----END PGP SIGNATURE----- Merge tag 'xtensa-20180820' of git://github.com/jcmvbkbc/linux-xtensa Pull Xtensa updates from Max Filippov: - switch xtensa arch to the generic noncoherent direct mapping operations - add support for DMA_ATTR_NO_KERNEL_MAPPING attribute - clean up users of platform/hardware.h in generic Xtensa code - fix assembly cache maintenance code for long cache lines - rework noMMU cache attributes initialization - add big-endian HiFi2 test_kc705_be CPU variant * tag 'xtensa-20180820' of git://github.com/jcmvbkbc/linux-xtensa: xtensa: add test_kc705_be variant xtensa: clean up boot-elf/bootstrap.S xtensa: make bootparam parsing optional xtensa: drop variant IRQ support xtensa: drop unneeded platform/hardware.h headers xtensa: move PLATFORM_NR_IRQS to Kconfig xtensa: rework {CONFIG,PLATFORM}_DEFAULT_MEM_START xtensa: drop unused {CONFIG,PLATFORM}_DEFAULT_MEM_SIZE xtensa: rework noMMU cache attributes initialization xtensa: increase ranges in ___invalidate_{i,d}cache_all xtensa: limit offsets in __loop_cache_{all,page} xtensa: platform-specific handling of coherent memory xtensa: support DMA_ATTR_NO_KERNEL_MAPPING attribute xtensa: use generic dma_noncoherent_ops

These cache attributes are set up for noMMU systems. Each hex digit
|
||||||
|
specifies cache attributes for the corresponding 512MB memory
|
||||||
|
region: bits 0..3 -- for addresses 0x00000000..0x1fffffff,
|
||||||
|
bits 4..7 -- for addresses 0x20000000..0x3fffffff, and so on.
|
||||||
|
|
||||||
|
Cache attribute values are specific for the MMU type, so e.g.
|
||||||
|
for region protection MMUs: 2 is cache bypass, 4 is WB cached,
|
||||||
|
1 is WT cached, f is illegal. For ful MMU: bit 0 makes it executable,
|
||||||
|
bit 1 makes it writable, bits 2..3 meaning is 0: cache bypass,
|
||||||
|
1: WB cache, 2: WT cache, 3: special (c and e are illegal, f is
|
||||||
|
reserved).
