366 * an earlier hw version had S71PL-J flash with 64 KiB sectors,
367 * and Pirelli's official fw supports both. They have modified
368 * TI's flash ID code to generate device ID 0x2100 for the J version
369 * or 0x2101 for the N version. We have now replicated this ID logic
370 * in our FreeCalypso code base, and we can now support both flash
371 * chip versions as well.
372 *
373 * Our FFS configuration for the Pirelli target is aftermarket.

372 // Let's use the first 2 MiB of the 2nd bank for the FFS. 388 * (we have only one board design so far, but hoping to have more),
389 * thus the set of possible flash chip types on FC hw platforms
390 * is expected to grow. The footprint on our current FCDEV3B PCB
391 * ideally fits Spansion MCPs with two chip select banks (either
392 * S71PL-J or S71PL-N), but can also be fitted with Openmoko's
393 * Samsung K5A3281. Spansion S71PL129NC0HFW4B (copied from the
394 * Pirelli DP-L10) is our official flash+RAM chip, populated on
395 * our production boards, but now that we have fixed TI's autodetect
396 * code to work with the newer Spansion chips, we can support
397 * all 3 possibilities in our fw with autodetection: S71PL-J,
398 * S71PL-N or K5A32xx.
399 *
400 * For future FreeCalypso hw designs, the Mother's plan is to
401 * keep the high-capacity S71PL129NC0HFW4B for the handset prototype
402 * and UI development board, but for embedded modem products
403 * we will probably switch to Openmoko's K5A32xx.
