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!

58 If you say Y here, your CLPS711x-based kernel will use the bootstrap
59 mode memory map instead of the normal memory map.
60
61 Processors derived from the Cirrus CLPS-711X core support two boot
62 modes. Normal mode boots from the external memory device at CS0.
63 Bootstrap mode rearranges parts of the memory map, placing an
64 internal 128 byte bootstrap ROM at CS0. This option performs the
65 address map changes required to support booting in this mode.
66
67 You almost surely want to say N here.
