Pi Genesis

For those who don’t subscribe to c.s.r-pi:

In the beginning was the GPU. And the GPU was proprietary, and without
publically available documents. And the power supply said “Let there be
reset!” and the GPU awoke.

And lo, the GPU reached out to the SD card and read bootcode.bin, and
saw that it was good. And so bootcode.bin was executed.

And bootcode.bin reached out to the SD card and found start.elf, and
saw that it was good. And so start.elf was executed.

And the start.elf configured the system. RAM was divided between the GPU
and the ARM.

And the start.elf loaded the kernel into the ARM side of the RAM. And
the ARM was reset.

And the reset most likely proceeded in the manner described in the
technical reference manual for the ARM1176JZFS processor.
