Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

366 ** We now need to insert a short boot section into
367 ** the memory at the end of Sram2. This is normally (de)composed
368 ** of the last eight bytes of the download code. The
369 ** download has been assembled/compiled to expect to be
370 ** loaded from 0x7FFF downwards. We have loaded it
371 ** at some other address. The startup code goes into the small
372 ** ram window at Sram2, in the last 8 bytes, which are really
373 ** at addresses 0x7FF8-0x7FFF.
374 **
375 ** If the loadbase is, say, 0x7C00, then we need to branch to
376 ** address 0x7BFE to run the host.bin startup code. We assemble
377 ** this jump manually.
378 **
379 ** The two byte sequence 60 08 is loaded into memory at address
380 ** 0x7FFE,F. This is a local branch to location 0x7FF8 (60 is nfix 0,
381 ** which adds '0' to the .O register, complements .O, and then shifts
382 ** it left by 4 bit positions, 08 is a jump .O+8 instruction. This will
383 ** add 8 to .O (which was 0xFFF0), and will branch RELATIVE to the new
384 ** location. Now, the branch starts from the value of .PC (or .IP or
385 ** whatever the bloody register is called on this chip), and the .PC
386 ** will be pointing to the location AFTER the branch, in this case
387 ** .PC == 0x8000, so the branch will be to 0x8000+0xFFF8 = 0x7FF8.
388 **
389 ** A long branch is coded at 0x7FF8. This consists of loading a four
390 ** byte offset into .O using nfix (as above) and pfix operators. The
391 ** pfix operates in exactly the same way as the nfix operator, but
392 ** without the complement operation. The offset, of course, must be
393 ** relative to the address of the byte AFTER the branch instruction,
394 ** which will be (urm) 0x7FFC, so, our final destination of the branch
395 ** (loadbase-2), has to be reached from here. Imagine that the loadbase
396 ** is 0x7C00 (which it is), then we will need to branch to 0x7BFE (which
397 ** is the first byte of the initial two byte short local branch of the
398 ** download code).
399 **
400 ** To code a jump from 0x7FFC (which is where the branch will start
401 ** from) to 0x7BFE, we will need to branch 0xFC02 bytes (0x7FFC+0xFC02)=
402 ** 0x7BFE.
403 ** This will be coded as four bytes:
404 ** 60 2C 20 02
405 ** being nfix .O+0
406 ** pfix .O+C
407 ** pfix .O+0
408 ** jump .O+2
409 **
410 ** The nfix operator is used, so that the startup code will be
411 ** compatible with the whole Tp family. (lies, damn lies, it'll never
412 ** work in a month of Sundays).
413 **
414 ** The nfix nyble is the 1s complement of the nyble value you
415 ** want to load - in this case we wanted 'F' so we nfix loaded '0'.
