Patch 27/28, OTOH, brings a bit of a change to how MMU code allocates PTEs, postponing that until the users of DMA API actually request that. Feedback is welcome! Changes since [v2]: - Dropped create_sections() macro. - Fixed a bug in 6/28, pointed out by Sam - Minor style changes and comment re-wording Changes since [v1]: - create_sections() reworked to keep all of its arguments 32-bits - Fixed compliation error in 9/28 - Small style fix for 26/28 - Collected Reviewed-by's from Lucas [v1] http://lists.infradead.org/pipermail/barebox/2018-May/032816.html [v2] http://lists.infradead.org/pipermail/barebox/2018-May/032880.html Andrey Smirnov (28): ARM: mmu: Remove unused ARM_VECTORS_SIZE ARM: mmu: Make use of IS_ALIGNED in arm_mmu_remap_sdram() ARM: mmu: Use ALIGN and ALIGN_DOWN in map_cachable() ARM: mmu: Introduce set_ttbr() ARM: mmu: Introduce set_domain() ARM: mmu: Share code for create_sections() ARM: mmu: Separate index and address in create_sections() sizes.h: Sync with Linux 4.16 ARM: mmu: Specify size in bytes in create_sections() ARM: mmu: Share code for initial flat mapping creation ARM: mmu: Share PMD_SECT_DEF_CACHED ARM: mmu: Drop needless shifting in map_io_sections() ARM: mmu: Replace hardcoded shifts with pgd_index() from Linux ARM: mmu: Trivial simplification in arm_mmu_remap_sdram() ARM: mmu: Replace various SZ_1M with PGDIR_SIZE ARM: mmu: Use PAGE_SIZE when specifying size of one page ARM: mmu: Define and use PTRS_PER_PTE ARM: mmu: Use PAGE_SIZE instead of magic right shift by 12 ARM: mmu: Use xmemalign in arm_create_pte() ARM: mmu: Use xmemalign in mmu_init() ARM: mmu: Share code between dma_alloc_*() functions ARM: mmu: Pass PTE flags a parameter to arm_create_pte() ARM: mmu: Make sure that address is 1M aligned in arm_create_pte() ARM: mmu: Use find_pte() to find PTE in create_vector_table() ARM: mmu: Use dma_inv_range() in dma_sync_single_for_cpu() ARM: mmu: Simplify the use of dma_flush_range() ARM: mmu: Implement on-demand PTE allocation ARM: mmu: Introduce ARM_TTB_SIZE arch/arm/boards/phytec-som-imx6/lowlevel.c | 1 + arch/arm/cpu/mmu-early.c | 31 +- arch/arm/cpu/mmu.c | 322 ++++++++++----------- arch/arm/cpu/mmu.h | 44 +++ arch/arm/include/asm/barebox-arm.h | 8 +- include/linux/sizes.h | 4 + 6 files changed, 212 insertions(+), 198 deletions(-) -- 2.17.0 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
