[PATCH 0/4] Add relocatable address support for jump and payload firmware

[Inochi Amaoto]

If FW_PIC=y is defined, the jump and payload firmware and will
be broken if FW_TEXT_START is wrong. This is not the desired behavior.

Add some new variable to support relocatable address.

build command:
make BUILD_INFO=y DEBUG=1 FW_PIC=y PLATFORM=generic FW_TEXT_START=0x0

test command:
qemu-system-riscv64 -smp cpus=4 -M virt -m 256M \
  -bios build/platform/generic/firmware/fw_payload.bin

Inochi Amaoto (4):
  firmware: Add relocatable FW_JUMP_ADDR and FW_JUMP_FDT_ADDR
  firmware: Add relocatable FW_PAYLOAD_FDT_ADDR
  platform: Apply relocatable address
  doc/firmware: add new configuration options for jump and payload
    firmware
