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!

4 | - CPLD memory mapping | ||
5 | |||
6 | The board designers chose to use high address lines for controlling | ||
7 | access to the CPLD registers. It turns out to be a big waste | ||
8 | because we're using an MMU and must map IO space into virtual | ||
9 | memory. The result is that we have to make a mapping for every | ||
10 | register. | ||

12 | - Serial Console | ||
13 | |||
14 | It may be OK not to use the serial console option if the user passes | ||
15 | the console device name to the kernel. This deserves some exploration. | ||
