The data structures in this code come from:
OMAP35x Applications Processor Technical Reference Manual chapter 25
OMAP34xx Multimedia Device Technical Reference Manual chapter 26.4.8.
You should use the OMAP35x manual when possible. Some things, like SectionKey,
are not defined in the OMAP35x manual and you have to use the OMAP34xx manual
to find the data.
