384 * Our FreeCalypso hardware family is currently in its infancy 384 * This table of flash devices covers those possibilities that may occur
385 * (we have only one board design so far, but hoping to have more), 385 * on FreeCalypso-branded hardware; we use a new table separate from the
386 * thus the set of possible flash chip types on FC hw platforms 386 * one we inherited from TI/Openmoko. Originally we had no choice because

388 * ideally fits Spansion MCPs with two chip select banks (either 388 * working autodetection, but we still use a separate device table for a
389 * S71PL-J or S71PL-N), but can also be fitted with Openmoko's 389 * few reasons:
390 * Samsung K5A3281. Spansion S71PL129NC0HFW4B (copied from the
391 * Pirelli DP-L10) is our official flash+RAM chip, populated on
392 * our production boards, but now that we have fixed TI's autodetect
393 * code to work with the newer Spansion chips, we can support
394 * all 3 possibilities in our fw with autodetection: S71PL-J,
395 * S71PL-N or K5A32xx.
396 * 390 *
397 * For future FreeCalypso hw designs, the Mother's plan is to 391 * 1) Our 16 MiB flash options (S71PL129N and S71PL129J) are specific
398 * keep the high-capacity S71PL129NC0HFW4B for the handset prototype 392 * to CONFIG_TARGET_FCFAM;
399 * and UI development board, but for embedded modem products 393 *
400 * we will probably switch to Openmoko's K5A32xx. 394 * 2) We gain additional freedoms like having a different FFS config
395 * for K5A32xxCTM flash in FCFAM vs. Openmoko;
396 *
397 * 3) Less clutter is always good.
