yosemite flash confusion

[Peter Fercher]

hi,
the yosemite (revision 1.1) i got has a 512 MBit Flash chip on it
(S29GL512).
u-boot 1.1.3 that came with it was configured to use only 32 Mbytes ???

trying to use the whole size of the flashchip on the board I run into the
following problem:
when i try to use the u-boot.bin (newest from the denx homepage:
ftp://ftp.denx.de/pub/u-boot/images/amcc/yosemite/) then i get:
(reprogrammed using the yosemite.cfg that was mailed to this list some days
ago)
U-Boot 1.1.4 (Oct 24 2005 - 09:23:33)

Type "run flash_nfs" to mount root filesystem over NFS

Hit any key to stop autoboot:  0

it sees the 64MB flash but somehow can't find the ethernet anymore..
does anybody know what the problem is there ?

cheers, peter
