Originally there are three iomem regions:\niomem32_low, iomem8, iomem32_highm. Since these regions only support\n4 bytes/1 byte/4 bytes access, it is divided into three regions.\n\nNow it is merged into one region, this regions supports 1/2/4/8 bytes\naccess.\n\nPatch 1-6 is to replace register name, no function change.\nPatch 7-16 is to use unifed memory region iomem, and supports 1/2/4/8\nbytes access with read/write ops for this region, and merge three\nregions above into one.\n\n---\n v2 ... v3:\n 1. Set address aligned with 8 bytes in memory region function\n pch_pic_read() and pch_pic_write(), and only compare register\n base address with 8 bytes aligned one.\n 2. Replace 0xff/0xffff with UCHAR_MAX/USHRT_MAX.\n\n v1 ... v2:\n 1. Add 1/2/4/8 bytes access support with memory region read and\n write ops.\n 2. Merge three memory regions iomem32_low, iomem8 and iomem32_high\n into one region iomem.\n 3. Merge trace functions for ops in above three memory regions into\n one trace function\n---\n\nBibo Mao (16):\n hw/intc/loongarch_pch: Modify name of some registers\n hw/intc/loongarch_pch: Modify register name PCH_PIC_xxx_OFFSET with\n PCH_PIC_xxx\n hw/intc/loongarch_pch: Remove some duplicate macro\n hw/intc/loongarch_pch: Set version information at initial stage\n hw/intc/loongarch_pch: Use relative address in MemoryRegionOps\n hw/intc/loongarch_pch: Discard write operation with ISR register\n hw/intc/loongarch_pch: Use generic read callback for iomem32_low\n region\n hw/intc/loongarch_pch: Use generic read callback for iomem32_high\n region\n hw/intc/loongarch_pch: Use generic read callback for iomem8 region\n hw/intc/loongarch_pch: Use generic write callback for iomem32_low\n region\n hw/intc/loongarch_pch: Use generic write callback for iomem32_high\n region\n hw/intc/loongarch_pch: Use generic write callback for iomem8 region\n hw/intc/loongarch_pch: Use unified trace event for memory region ops\n hw/intc/loongarch_pch: Rename memory region iomem32_low with iomem\n hw/intc/loongarch_pch: Set flexible memory access size with iomem\n region\n hw/intc/loongarch_pch: Merge three memory region into one\n\n hw/intc/loongarch_pch_pic.c | 344 +++++++++----------------\n hw/intc/trace-events | 8 +-\n hw/loongarch/virt.c | 6 -\n include/hw/intc/loongarch_pic_common.h | 57 ++--\n 4 files changed, 152 insertions(+), 263 deletions(-)\n\n\nbase-commit: dfaecc04c46d298e9ee81bd0ca96d8754f1c27ed" }
