This work is based on the original work by Li Guang with extra
features added by Peter C and myself.
The idea of this loader is to allow the user to load multiple images
or values into QEMU at startup.
Memory values can be loaded like this: -device
loader,addr=0xfd1a0104,data=0x8000000e,data-len=4
Images can be loaded like this: -device loader,file=./images/u-boot.elf,cpu=0
This can be useful and we use it a lot in Xilinx to load multiple images
into a machine at creation (ATF, Kernel and DTB for example).
It can also be used to set registers.
The limiation for arch is based off settting the ELF_ARCH macro.
The reset patch is required otherwise the reset will never be registered
and the loader can't change the PC in the case of images.
V2:
- Add an entry to the maintainers file
- Add some documentation
- Perform bounds checking on the data_len
- Register and unregister the reset in the realise/unrealise
Changes since RFC:
- Add support for BE
