The goal is to have a clean API ready for\nharder refactor.\n\nFirst we remove the _notdirty() and leul_to_cpu() helpers,\nthen we prepare the subpage_ops[] MemoryRegionOps to handle\ndistinct endianness in the same binary, and finally we add\na pair of ldm()/stm() variants to directly infer the access\nsize and endianness from a MemOp argument.\n\n(As a bonus we also moved MemoryRegionCache out of memory.h).\n\nPlease review,\n\nPhil.\n\nPhilippe Mathieu-Daudé (14):\n target/i386: Remove x86_stl_phys_notdirty() leftover\n target/sparc: Update MMU page table using stl_phys()\n hw/arm: Update bootloader generated with '-kernel' using stl_phys()\n system/memory: Remove address_space_stl_notdirty and stl_phys_notdirty\n system/physmem: Inline and remove leul_to_cpu()\n system/physmem: Use explicit endianness in subpage_ops::read/write()\n system/memory: Split MemoryRegionCache API to 'memory_cached.h'\n system/memory: Inline address_space_stq_internal()\n system/memory: Define address_space_ldst[W] endian variants via\n template\n system/memory: Define address_space_ldst[L] endian variants via\n template\n system/memory: Define address_space_ldst[Q] endian variants via\n template\n system/memory: Factor address_space_ldst[M]_internal() helper out\n system/memory: Pass device_endian argument as MemOp bit\n system/memory: Sort methods in memory_ldst.c.inc file\n\n MAINTAINERS | 3 +\n include/hw/virtio/virtio-access.h | 1 +\n include/qemu/bswap.h | 11 -\n include/system/memory.h | 191 -------\n include/system/memory_cached.h | 207 ++++++++\n target/i386/cpu.h | 1 -\n include/exec/memory_ldst.h.inc | 52 +-\n include/exec/memory_ldst_phys.h.inc | 111 +---\n include/system/memory_ldst_endian.h.inc | 33 ++\n include/system/memory_ldst_phys_endian.h.inc | 57 ++\n hw/arm/aspeed.c | 3 +-\n hw/arm/boot.c | 6 +-\n system/physmem.c | 87 +++-\n target/i386/helper.c | 10 -\n target/sparc/mmu_helper.c | 2 +-\n system/memory_ldst.c.inc | 514 ++++---------------\n system/memory_ldst_endian.c.inc | 64 +++\n 17 files changed, 546 insertions(+), 807 deletions(-)\n create mode 100644 include/system/memory_cached.h\n create mode 100644 include/system/memory_ldst_endian.h.inc\n create mode 100644 include/system/memory_ldst_phys_endian.h.inc\n create mode 100644 system/memory_ldst_endian.c.inc" }
