[Qemu-devel] [PULL 4/5] hw/arm/boot: Rename elf_{low, high}_addr to image_{low, high}_addr

[Peter Maydell <peter.maydell@linaro.org>]

Rename the elf_low_addr and elf_high_addr variables to image_low_addr
and image_high_addr -- in the next commit we will extend them to
be set for other kinds of image file and not just ELF files.
