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).
Tested with the latest Xilinx ZynqMP machine, if I enable EL3 and EL2 I can
boot ATF through to u-boot using the loader to load the images.
It can also be used to set registers.
This patch series makes the load_elf() function more generic by not
requiring an architecture. It also adds new functions load_elf_as(),
load_uimage_as and load_image_targphys_as which allows custom
AddressSpaces when loading images.
V12:
- All patches have been reviewed
- Most patches have been merged
- The commit message of the actual device patch has been updated to
justify why it is a device.
