Handle magneto-optical scsi device commands

For platforms that do not have non-blocking read from SCSI bus

Once DMA has finished, check if all PIO queues have been drained

Generate parity and GPIO words in 16-bit bus mode. Reads count bytes from src and writes count/2 words to dest. Only 18 bottom bits of the output word

Generate parity and GPIO words in 8-bit bus mode. Reads count bytes from src and writes count words to dest. Only DBP and bits 0-7 of the output word

SD Card Communication Autoconfig

Shorten absolute paths to be relative to common prefixes.

Create a serializable snapshot of an ELF's layout.

Swap filled read buffer to be processed, and other one for DMA usage. Sets dma_iobuf_words according to remaining space in application buffer. Returns

Rebuild a minimal CUETrackInfo from the cached fields so the header-only math helpers can be called without keeping a full CUETrackInfo in .bss.

Grab input from USB Serial terminal

* Simple deterministic hash for UUID generation. * Mixes timestamp, SCSI ID, and disk size into 16 bytes. * Uses a basic multiplicative hash (FNV-1a

Write a big-endian uint16 to buffer */

usb framework checks this func exists for mass storage config. no code needed.
