Please do this instead:
extern int macb_eth_initialize(int id, void *regs, unsigned int phy_addr);
#if defined(CONFIG_MACB) && defined(CONFIG_CMD_NET)
int board_eth_init(bd_t *bi)
{
return macb_eth_initialize(0, (void *)MACB0_BASE, bi->bi_phy_id[0]);
}
#endif
And move it to

Is this flash CFI-compliant? If so, please use the CFI driver.
Otherwise, ignore me.
