So its a S29GL256 with 32MBytes...

That's not correct anymore. A recent patch from Grant Erickson [ibm_newemac: 
Parameterize EMAC Multicast Match Handling] changed these compatible entries. 
You should use "ibm_emac4sync" here now.

The patch mentioned above also cfixed the incorrect size here. Please fix this 
too.

SGMII, right?

All EMAC related comment above are valid for all EMAC nodes of course.
