-The first generation of Altus Metrum products were all based on the TI cc1111,
-which has an 8051 core. We started out using standard SDCC, but Keith made a
-number of changes to better support the cc1111, and then SDCC 3.X changed code
-generation such that 8051 executables became significantly larger and our code
-just wouldn't fit in available flash any more!
-
-As a result, we maintain a fork of SDCC we call 'cc1111' that is based
-on the last upstream version of SDCC 2.X, plus a highly modified sdcdb with
-support for the cc1111 debugging interface. This is avilable as a package in
-Debian, or you can find the sources on [git.gag.com](http://git.gag.com)
-in the project [debian/cc1111](http://git.gag.com/?p=debian/cc1111;a=summary).

-### AVR
-
-We use the standard gcc-avr tools for this target, which thanks to the
-popularity of the [Arduino](http://arduino.cc) community are well taken care
-of in Debian.

-### ARM Cortex
-
-Most of the new products we're working on now are based on system on chip
-parts using ARM Cortex M3 or ARM Cortex M0 cores. These require a "bare metal"
-toolchain, not the standard ARM compiler and libraries used for ARM Linux. We
-continue to discuss our needs with others in the Debian community and have
-high hopes for a suitable toolchain to eventually be part of the main
-distribution. But, in the meantime, here's what it takes to build a suitable
-toolchain in /opt/cortex:
-
-* mkdir /opt/cortex, and ensure it's owned by you (so no root privs are needed)
-* clone our [cortex-toolchain](http://git.gag.com/?p=fw/cortex-toolchain;a=summary) with `git clone git://git.gag.com/fw/cortex-toolchain`
-* cd into the cortex-toolchain directory, review the list of build dependencies
- documented in the README file, then build using
- `./summon-arm-toolchain`. This will download all
- the source packages, unpack them, build everything, and install it all in
- /opt/cortex automatically. This takes a bunch of disk space and a lot of
- time, so be patient!
-* clone our [pdclib](http://git.gag.com/?p=fw/pdclib;a=summary) C library
- repository with `git clone git://git.gag.com/fw/pdclib`
-* cd into the pdclib directory, and build using `make ; make install` which
- will build the library using the just-installed cortex tools and deliver
- the results to the /opt/cortex tree
-
-That's it! You should now have an ARM toolchain targetting bare metal for
-both Cortex M0 and M3 variants including a minimal C runtime library.
