[U-Boot] [RAM MEMORY] Hardware Replacement.

[Rodolfo Oliveira]

 Hi,
I'm upgrading my hardware RAM, but I found a problem.
After replacing the RAM MT48LC32M4A2 by IS42S16800E the following message
appeared:
"Memory (date line) error at 00000000, wrote aaaaaaaaaaaaaaaa, read
89abcdef89abc def!"
This error happens in executing the u-boot.

Does anyone know what problem is this?
I looked at the two memories and ram it are similar.

Thanks,
Rodolfo Romão.
