405 SDRAM: - The SDRAM parameters can now be defined in the board
config file and the 405 SDRAM controller values will
be calculated upon bootup (see PPChameleonEVB).
When those settings are not defined in the board
config file, the register setup will be as it is now,
so this implementation should not break any current
design using this code.
Thanks to Andrea Marson from DAVE for this patch.
440 DDR: - Added function sdram_tr1_set to auto calculate the
TR1 value for the DDR.
- Added ECC support (see p3p440).
