Describe the write-once usage model, the strict in-place mmap and what MAP_XIP_STRICT is for, extent pinning, manual defragmentation and how to read its result, the power-loss ordering, the on-media layout, and the limitations. The NXFLAT page said ROMFS was the only file system able to serve the XIP mappings its loader needs. That is now one of two, so point at both, and at what the writable one adds: a module can arrive at run time instead of being baked into a host-built image.
