Subject: [Qemu-devel] [PATCH v12 0/2]  Add a generic loader
Date: Wed, 28 Sep 2016 15:44:36 -0700	[thread overview]
Message-ID: <cover.1475102513.git.alistair.francis@xilinx.com> (raw)

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.
