[Qemu-devel] [PATCH v3 0/2] Add a generic loader


From: Alistair Francis
Subject: [Qemu-devel] [PATCH v3 0/2] Add a generic loader
Date: Fri, 19 Feb 2016 12:40:28 -0800

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
