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!

+/* Dreamcast System ASIC Hardware Events -
+
+ The Dreamcast's System ASIC (a.k.a. Holly) is responsible for receiving
+ hardware events from system peripherals and triggering an SH7750 IRQ.
+ Hardware events can trigger IRQs 13, 11, or 9 depending on which bits are
+ set in the Event Mask Registers (EMRs). When a hardware event is
+ triggered, it's corresponding bit in the Event Status Registers (ESRs)
+ is set, and that bit should be rewritten to the ESR to acknowledge that
+ event.
+
+ There are three 32-bit ESRs located at 0xa05f8900 - 0xa05f6908. Event
+ types can be found in include/asm-sh/dc_sysasic.h. There are three groups
+ of EMRs that parallel the ESRs. Each EMR group corresponds to an IRQ, so
+ 0xa05f6910 - 0xa05f6918 triggers IRQ 13, 0xa05f6920 - 0xa05f6928 triggers
+ IRQ 11, and 0xa05f6930 - 0xa05f6938 triggers IRQ 9.
+
+ In the kernel, these events are mapped to virtual IRQs so that drivers can
+ respond to them as they would a normal interrupt. In order to keep this
+ mapping simple, the events are mapped as:
+
+ 6900/6910 - Events 0-31, IRQ 13
+ 6904/6924 - Events 32-63, IRQ 11
+ 6908/6938 - Events 64-95, IRQ 9
