Where can I read about how flash storage / fault tolerant writes are
supposed to work? Like spare area, reclaim, the PCDs we had to adjust
recently for secure boot, and so on. The series is currently Greek to
me, I need to educate myself.

This is a complex area I think. For example the NvVars stuff in OVMF
only got clear(er) to me when I spent half a day on Michael Chang's
patch and the code it touches -- it's completely non-intuitive that OVMF
has a memory buffer as flash storage (with fault tolerant writes) which
is snooped on by another component that writes to a file during the boot
phase whatever it hears. Or some such. (I could easily be confused still...)

Thanks!
Laszlo
