Yes, but it was compiled differently afaik so you won't arrive at the
same binary.

Well, not TYPE=AP, but we'll integrate whatever is necessary into one
firmware, I expect. It shouldn't be very hard given that AP mode really
works with the TYPE=STA firmware already, almost.

The eeprom is mapped there, but I don't think it's 1M, it's just the max
size of the mapping to the CPUs address space.

This is just memory. It's used for buffering frames and dma descriptors
etc. internally. I want to change the code to do this with the linker
script rather than manually assigning addresses in the source. But if
you grep for this address you'll find how it's used.

Yeah, we're not exactly sure about this yet, but using 32k definitely
crashes the device.
