Subject[PATCH v2 18/19] OpenRISC: Miscellaneous
Date

Adds README file, TODO list, config file for or1ksim simulator, and a
couple of other pieces that didn't seem to fit into any other patch.

+OpenRISC Linux
+==============
+
+This is a port of Linux to the OpenRISC class of microprocessors; the initial
+target architecture, specifically, is the 32-bit OpenRISC 1000 family (or1k).
+
+For more information about OpenRISC processors and ongoing development:
+
+ website http://openrisc.net
+
+Additional information, though not kept up to date by the site maintainers,
+can be found at http://opencores.org/openrisc
+
+For information about Linux on OpenRISC, please contact South Pole AB.

+
+Build instructions for OpenRISC toolchain and Linux
+===================================================
+
+In order to build and run Linux for OpenRISC, you'll need at least a basic
+toolchain and, perhaps, the architectural simulator. Steps to get these bits
+in place are outlined here.
+
+1) The toolchain can be obtained from openrisc.net. Instructions for building
+a toolchain can be found at:
+
+http://openrisc.net/toolchain-build.html
+
+2) or1ksim (optional)
+
+or1ksim is the architectural simulator which will allow you to actually run
+your OpenRISC Linux kernel if you don't have an OpenRISC processor at hand.
+
+ git clone git://openrisc.net/jonas/or1ksim-svn
+
+ cd or1ksim
+ ./configure --prefix=$OPENRISC_PREFIX
+ make
+ make install
+
+3) Linux kernel
+
+Build the kernel as usual
+
+ make ARCH=openrisc defconfig
+ make ARCH=openrisc
+
+4) Run in architectural simulator
+
+There's a configuration file for the architectural simulator (or1ksim) in the
+arch/openrisc directory, allowing you to run your kernel with the following
+incantation:
+
+ sim -f arch/openrisc/or1ksim.cfg vmlinux
+
+---------------------------------------------------------------------
+
+Terminology
+===========
+
+In the code, the following particles are used on symbols to limit the scope
+to more or less specific processor implementations:
+
+openrisc: the OpenRISC class of processors
+or1k: the OpenRISC 1000 family of processors
+or1200: the OpenRISC 1200 processor
+
+---------------------------------------------------------------------
+
+History
+========
+
+18. 11. 2003 Matjaz Breskvar (phoenix@bsemi.com)
+ initial port of linux to OpenRISC/or32 architecture.
+ all the core stuff is implemented and seams usable.
+
+08. 12. 2003 Matjaz Breskvar (phoenix@bsemi.com)

+ a much improved version with changes all around.
+
+10. 04. 2004 Matjaz Breskvar (phoenix@bsemi.com)
+ alot of bugfixes all over.
+ ethernet support, functional http and telnet servers.
+ running many standard linux apps.
+
+26. 06. 2004 Matjaz Breskvar (phoenix@bsemi.com)
+ port to 2.6.x
+
+30. 11. 2004 Matjaz Breskvar (phoenix@bsemi.com)

+The OpenRISC Linux port is fully functional and has been tracking upstream
+since 2.6.35. There are, however, remaining items to be completed within
+the coming months. Here's a list of known-to-be-less-than-stellar items
+that are due for investigation shortly, i.e. our TODO list:
+
+Implement the rest of the DMA API... dma_map_sg, etc.
+
+Consolidate usage of memblock and bootmem... move everything over to memblock.
+
+Clean up defconfigs:
+- remove initramfs, cross-compile, local version, etc.
+
+Finish the renaming cleanup... there are references to or32 in the code
+which was an older name for the architecture. The name we've settled on is
+or1k and this change is slowly trickling through the stack. For the time
+being, or32 is equivalent to or1k.
+
+Implement optimized version of memcpy and memset

+/* INTRODUCTION
+
+ The ork1sim has various parameters, that are set in configuration files
+ like this one. The user can switch between configurations at startup by
+ specifying the required configuration file with the -f <filename.cfg> option.
+ If no configuration file is specified or1ksim searches for the default
+ configuration file sim.cfg. First it searches for './sim.cfg'. If this
+ file is not found, it searches for '~/or1k/sim.cfg'. If this file is
+ not found too, it reverts to the built-in default configuration.
+
+ NOTE: Users should not rely on the built-in configuration, since the
+ default configuration may differ between version.
+ Rather create a configuration file that sets all critical values.
+
+ This file may contain (standard C) comments only - no // support.
+
+ Configure files may be be included, using:
+ include "file_name_to_include"
+
+ Like normal configuration files, the included file is divided into
+ sections. Each section is described in detail also.
+
+ Some section have subsections. One example of such a subsection is:
+
+ device <index>
+ instance specific parameters...
+ enddevice
+
+ which creates a device instance.
