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. This patch series also make the load_elf() function more generic by not requiring an architecture. V5: - Rebase V4: - Re-write documentation - Allow the loader to work with every architecture - Move the file to hw/core - Increase the maximum number of CPUs - Make the CPU operations conditional - Convert the cpu option to cpu-num - Require the user to specify endianess 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 Alistair Francis (3): loader: Allow ELF loader to auto-detect the ELF arch generic-loader: Add a generic loader docs: Add a generic loader explanation document MAINTAINERS | 6 ++ docs/generic-loader.txt | 56 +++++++++++++++ hw/core/Makefile.objs | 2 + hw/core/generic-loader.c | 145 +++++++++++++++++++++++++++++++++++++++ hw/core/loader.c | 10 +++ include/hw/core/generic-loader.h | 45 ++++++++++++ 6 files changed, 264 insertions(+) create mode 100644 docs/generic-loader.txt create mode 100644 hw/core/generic-loader.c create mode 100644 include/hw/core/generic-loader.h -- 2.7.4
