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!

+ If you say Y here, your CLPS711x-based kernel will use the bootstrap

+
+ Processors derived from the Cirrus CLPS-711X core support two boot
+ modes. Normal mode boots from the external memory device at CS0.
+ Bootstrap mode rearranges parts of the memory map, placing an
+ internal 128 byte bootstrap ROM at CS0. This option performs the
+ address map changes required to support booting in this mode.
+
+ You almost surely want to say N here.
