[U-Boot] Does U-boot supports Spansion S29GL512P NOR Flash?

Hi Frank,

>> What CPU are you using, and what chip-select is the flash using?
I am using PPC440x5 Cpu core. How to check the chip-select flash is using?
Earlier I have run the same code for M29W128GH and it works fine. But with
S29GL512 it is not working.
Now the difference is only in size and write/read timings. So I believe it
should work in smooth manner.


kilauea.h file is present in the U-boot.
So does this board supports S29GL512P Nor flash chip?


Regards,
Prakash
