Zoom2 and 3 have UARTs only on the external debug board. GPMC needs to be mapped early to use it for DEBUG_LL. Additionally, 0xfb000000 overlaps with other areas, so use 0xfa400000 for the virtual address instead. Note that with the pending serial.c patches you need to set console=ttyS0,115200n8 as it will be the only UART mapped. To use DEBUG_LL, you need to pass also earlyprintk in cmdline.
