This kinda documents how I got the bootrom for some of the other work I did and posted here a while back (and also CVE-2021-27208).

Planning to publish the CVE writeup soon, but otherwise there are a few more stones to overturn:

• fabric boot - basically, the ARM cores spin until the FPGA fabric comes up, then boot off AXI

• bitstream encryption/decryption (is it possible?)

We'll see which and in what order I eventually get around to those - I'd be plenty happy if someone beat me to it ;)
