The mask ROM inside the EP9302 is 16 kilobytes.  This is the part that
does the boot from serial/SPI/memory/etc that is described in the EP93xx
data sheets.

The TS7250 has NAND flash, and the EP93xx (and many other CPUs) can't
boot directly off NAND flash, so that's probably why (I'm taking your
word on that, I didn't check the board too closely myself) there is an
additional EEPROM on the board (containing the TS-NANDBOOT code) from
which the CPU can boot, to load the 'real' boot loader and Redboot after
that.

Does that make sense?
