- Add Intel legacy lock/unlock support to common CFI driver
On some Intel flash's (e.g. Intel J3) legacy unlocking is
supported, meaning that unlocking of one sector will unlock
all sectors of this bank. Using this feature, unlocking
of all sectors upon startup (via env var "unlock=yes") will
get much faster.
- Fixed problem with multiple reads of envronment variable
"unlock" as pointed out by Reinhard Arlt & Anders Larsen.
- Removed unwanted linefeeds from "protect" command when
CFG_FLASH_PROTECTION is enabled.
- Changed p3p400 board to use CFG_FLASH_PROTECTION
Patch by Stefan Roese, 01 Apr 2006
* Changes/fixes for drivers/cfi_flash.c:
- Correctly handle the cases where CFG_HZ != 1000 (several
XScale-based boards)
- Fix the timeout calculation of buffered writes (off by a
factor of 1000)
Patch by Anders Larsen, 31 Mar 2006
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).
Patch by Stefan Roese, 17 Mar 2006
- Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c
- CFG_FLASH_QUIET_TEST added to use the common CFI driver
for bank autodetection

before we can access it; add delay in case we are faster (with no
CF card inserted)
* Cleanup of some init functions
* Make sure SCC Ethernet is always stopped by the time we boot Linux
to avoid Linux crashes by early packets coming in.
* Accelerate flash accesses on LWMON board by using buffered writes
