This series adds boot elf kernel with FDT. 'LoongArch supports ACPI and FDT. The information that needs to be passed to the kernel includes the memmap, the initrd, the command line, optionally the ACPI/FDT tables, and so on' see [1]. Patch 2-8 : Create efi system table, and three efi configuration table boot_memmap, initd, FDT. Patch 9-17 : Fixes FDT problems. Test: - Start kernel See [2] start_kernel.sh - Start qcow2 See [2] start_qcow2.sh Patch 3 and Patch 6 need to be reviewed. Thanks. Song Gao V7: - Rebase and R-b; - Patch3, replace reg_num with reg_name. move slave boot code buf to pflash0; - Patch5: replace __aligned(8) with QEMU_ALIGNED(8); - Patch8: Use the macro FDT_BASE to indicate the fdt base size. V6: - Fixes test/compilation failures; V5: - Rebase; V4: - patch 3 change slave_boot_code[] to const, and 'static void *p ' to 'void *p'; - patch 4 fixes build error; - patch 10-13, add project and commit link. V3: - Load initrd at kernel_high + 4 * kernel_size; - Load 'boot_rom' at [0 - 1M], the 'boot_rom' includes slave_boot_code, cmdline_buf and systab_tables; - R-b and rebase. V2: - FDT pcie node adds cells 'msi-map'; [1]: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/arch/loongarch/booting.rst?h=v6.7-rc4 [2]: https://github.com/gaosong-loongson/loongarch-binary/releases Song Gao (17): hw/loongarch: Move boot functions to boot.c hw/loongarch: Add load initrd hw/loongarch: Add slave cpu boot_code hw/loongarch: Add init_cmdline hw/loongarch: Init efi_system_table hw/loongarch: Init efi_boot_memmap table hw/loongarch: Init efi_initrd table hw/loongarch: Init efi_fdt table hw/loongarch: Fix fdt memory node wrong 'reg' hw/loongarch: fdt adds cpu interrupt controller node hw/loongarch: fdt adds Extend I/O Interrupt Controller hw/loongarch: fdt adds pch_pic Controller hw/loongarch: fdt adds pch_msi Controller hw/loongarch: fdt adds pcie irq_map node hw/loongarch: fdt remove unused irqchip node hw/loongarch: Add cells missing from uart node hw/loongarch: Add cells missing from rtc node include/hw/intc/loongarch_extioi.h | 1 + include/hw/loongarch/boot.h | 109 +++++++++ include/hw/loongarch/virt.h | 14 ++ include/hw/pci-host/ls7a.h | 2 + target/loongarch/cpu.h | 2 + hw/loongarch/boot.c | 337 ++++++++++++++++++++++++++ hw/loongarch/virt.c | 363 ++++++++++++++++------------- hw/loongarch/meson.build | 1 + 8 files changed, 669 insertions(+), 160 deletions(-) create mode 100644 include/hw/loongarch/boot.h create mode 100644 hw/loongarch/boot.c
