Check the nBYTE pin on the Spansion flash. For 16bit operation, it
should be connected to 3.3V.

We used the S29GL512P on 2009.08 too, so the problem is probably not
related to wrong version of U-Boot.
Your BDI configuration is the same we use, except for the ERASE command.

With an uninitialized memory controller, the CS0 is probably visible
at address 0x0. So the ERASE should be
ERASE 0x0 0x20000 512

Frank
