Okay, this patch will probably make Ron cry, but in the end, I think its better for the health of buildrom and the project (the patch, not Ron crying).
The OLPC code we had in here before was for revision B2 and earlier, which will never see the light of day to the public, and only myself, Ron and Segher have even seen them, let alone used them (and I'm not even sure if my B2 works).
Even if we were to revive LinuxBIOS for the B3 for the upcoming G1G1 effort, the existing code would be too bitrotten and too old to be of any use. The only use we had for it was as a decent example of how to do LAB, but Ward has upped the stakes with his LAB code that is way better, and if we have our way, eventually all the LAB code will go away in favor of something like buildroot. And finally, the OLPC buildrom code that last worked for B2 is still active over at dev.laptop.org, so the code will be accessible if need be.
So, with all that said, I am proposing this patch to remove OLPC support completely from buildrom, except for OFW, which I will discuss in the next patch. Flame on!

[BUILDROM] Remove bitrotten OLPC support
OLPC support is bitrotten, and will never really be useful for the general
public, so eliminate it.

-Revision is:
-
-Q - Manufacturer, i.e. Quanta
-1 - board revision number
-A - Major firmware revision
-82- Minor firmware revision
-
-------- Quanta describes their release sequence:
-
-Let me explain our ISO sequence: Qxxxx First x: 1 for A test, 2 for B test, 3 for C test Second x: A~Z: milestone Third x: 1~9: change when test team release to customer, manufacture (outside R&D) Forth x: 1~9: change when sw team release to test team.(inside R&D)
-
-Take EC as example: Q1A11 when sw team release to test team. Test team find some problems, can not relase out Q1A12 when sw team fix the problem and release to test team again Test team test OK, and release out
-
-Next version sw team release will be Q1A21
-
-As I mentioned we will use file name to distinguish the release.
-
-EC release will be PQ1A21.bin (Leading by P) BIOS release will be BQ2A11.bin (leading by B)

Okay, this patch will probably make Ron cry, but in the end, I think its better for the health of buildrom and the project (the patch, not Ron crying).
The OLPC code we had in here before was for revision B2 and earlier, which will never see the light of day to the public, and only myself, Ron and Segher have even seen them, let alone used them (and I'm not even sure if my B2 works).
Even if we were to revive LinuxBIOS for the B3 for the upcoming G1G1 effort, the existing code would be too bitrotten and too old to be of any use. The only use we had for it was as a decent example of how to do LAB, but Ward has upped the stakes with his LAB code that is way better, and if we have our way, eventually all the LAB code will go away in favor of something like buildroot. And finally, the OLPC buildrom code that last worked for B2 is still active over at dev.laptop.org, so the code will be accessible if need be.
So, with all that said, I am proposing this patch to remove OLPC support completely from buildrom, except for OFW, which I will discuss in the next patch. Flame on!
Call it a flame if you want, but:

If somebody needs some of this later (for reference or whatever), it's still in the repository...
Note: I have not tested the patch, I assume you tested it and it didn't break random other stuff?

Norwich built. I didn't try to get much more random then that.. :)

I've been thinking along the same lines. I still think LAB is the way to go, and I'm very happy to see all the great work Ward has done. I was going to try to close the loop once my home workshop is done (I just moved) and try it once again on my old OLPC units.
But the existing OLPC stuff is indeed bit-rotten.
