Alexander Boettcher 92db5d2c4e sel4: limit max relocation memory to 256M
relocation is required, to avoid overlapping phdr in the elf binaries, but
sel4 will fail to boot if bender relocates the images at the end of physical
memory. Limit the physical relocation address to a fixed 256M value, so that
sel4 will work.

This directory contains boot-loader files needed to boot Genode and to create
boot images. The tools are available in binary form. Pointers to the source
code respectively the download source of binaries are described below.
:'bender'
The 'bender' tool is part of the 'morbo' toolchain available under GPL.
The toolchain was obtained from https://github.com/TUD-OS/morbo.
For Genode the bender was modified so that binaries are only relocated up
to 2G physical. Additional, relocation can be limited to 256M for sel4.
The changes are available on the genode_bender branch of
https://github.com/alex-ab/morbo.git.
:'pulsar':
The 'pulsar' tool was obtained in binary form from
http://os.inf.tu-dresden.de/~us15/pulsar.
:'chain.c32', 'isolinux.bin'
These files are part of the 'Syslinux Project' hosting several bootloaders.
The sources has been obtained from http://www.syslinux.org.
:'stage2_eltorito':
This file is part of a modified Grub 0.97 available under GPL. The sources
of the modified Grub 0.97 were obtained from
http://os.inf.tu-dresden.de/~adam/grub.
:'unzip'
The 'unzip' tool is part of the 'morbo' toolchain available under GPL.
The toolchain was obtained from https://github.com/TUD-OS/morbo.
For Genode the unzip was modified so that raw binary images with a Multiboot
OS header can be loaded.
The changes are available on the genode_bender branch of
https://github.com/skalk/morbo.git.
