I am trying to port U-boot to a custom board based on IXDP425 The board needs to use network using the IXP425 NPE.

I defined CONFIG_IXP4XX_NPE

After compiling U-boot I got errors regarding CONFIG_PHYS_ADDR and CFG_CACHELINE_SIZE that are undefined.

I need some more information about these constants so I know how to define them.
