Openrisc Linux Kernel Patches and Etc.

The following are my Openrisc patches to the linux kernel that I have run on the Opencores simulator.
These patches are forked from the 2.6.15.7 version available from Opencores or BSEMI.

I am currently using and testing Busybox-1.4.1 and Busybox-1.5.0 which I have running
on the ramdisks --this was built with uClibc-0.9.28.3 which is posted too.

Since you can get a 2.6.15.7 image from Opencores or BSEMI and ports to 2.6.16 from that
should be pretty trivial so I am starting here from 2.6.17.

All of my Linux ports/patches require 3 things:
1) You have to get fresh kernel source of the exact kernel version in the patch name(i.e. linux-2.6.x).
2) You must copy linux-2.6.x/rgd_dot_config(included in the patch) to .config.
3) You should download my ramdisk and copy this to linux-2.6.x/arch/or32/support/initrd-fb-03.ext2.bz2
After you copy the zipped ramdisk to the location you must unzip it i.e. bunzip2 initrd-fb-03.ext2.bz2.

After this you should be able to do a "make vmlinux" and you should have a runnable image.
Also note that I have modified the sim.cfg file to use tcp on port 84 so you should be able
to do something like telnet 127.0.0.1 84 to get console access.

To Use (Linux patches)

a. Download/unzip/unpack MATCHING kernel source.
b. cd linux-2.6.x
c. bzip2 -dc ../whatever/linux_2.6.x_or32_unified_simtested.bz2 |patch -p1
d. cp rgd_dot_config .config
e. cp ../whatever/rgd_initrd-fb-03.ext2.bz2 arch/or32/support/initrd-fb-03.ext2.bz2
f. bunzip2 arch/or32/support/initrd-fb-03.ext2.bz2
g. make vmlinux ARCH=or32 CROSS_COMPILE=path_to_chain/whatever-
h. whatever-sim -f sim.cfg vmlinux
(note "whatever" is where you downloaded or installed it to)

To Use (uClibc-0.9.28.3 patches)

a. Download/unzip/unpack uClibc-0.9.28.3
b. cd uClibc-0.9.28.3/
c. bzip2 -dc ../whatever/uClibc-0.9.28-or32-unified.bz2 |patch -p1
d. cd libc
e. bzip2 -dc ../../whatever/uClibc-0.9.28-or32-libc-support.bz2
f. cd ../../
g. Follow the directions starting with the Config link here or here

This comes in handy if you are making kernel patches:
