Support to load DTB after 3GB on RV64 system, so that larger initrd doesn't be overlapped to DTB. DTB loading now will check if overlapping to kernel/initrd and report this error.
Verify the patch via running 4GB initramfs on the virt machine. Changes for v2: - Add DTB overlapping checking and struct RISCVBootInfo - Remove the commit to change #address-cell of 'initrd-[start|end]' Jim Shu (3): hw/riscv: Support to load DTB after 3GB memory on 64-bit system. hw/riscv: Add a new struct RISCVBootInfo hw/riscv: Add the checking if DTB overlaps to kernel or initrd hw/riscv/boot.c | 94 +++++++++++++++++++++--------- hw/riscv/microchip_pfsoc.c | 13 +++-- hw/riscv/opentitan.c | 4 +- hw/riscv/sifive_e.c | 4 +- hw/riscv/sifive_u.c | 14 ++--- hw/riscv/spike.c | 14 ++--- hw/riscv/virt.c | 13 +++-- include/hw/riscv/boot.h | 28 ++++++--- include/hw/riscv/microchip_pfsoc.h | 2 + include/hw/riscv/opentitan.h | 2 + include/hw/riscv/sifive_e.h | 2 + include/hw/riscv/sifive_u.h | 2 + include/hw/riscv/spike.h | 2 + include/hw/riscv/virt.h | 2 + 14 files changed, 130 insertions(+), 66 deletions(-) -- 2.17.1
