Not needed; copy the .tap file directly to the SD card, no partition
tables, no file system:

  dd if=foo.tap of=/dev/sdx

Fix up the firmwre (a SMOP) with a pointer to where you are in the .tap
data; it starts at block 0, offset 0 at the location would be the first
block size word of the .tap data. Treat the disk as a file; read reads the
data at the pointer and moves the pointer to the end of the read. Assuming
LBA, the pointer value maps directly to block number/offset.

Fill out the SCSI tape commands to use the pointer and the data.
