    ipq806x: ASRock g10: fix bogus read errors
    
    Properly declare that the g10 is booting from NAND and define its
    correct (larger than on other devices-) boot_pages_size, to prevent
    the kernel from constantly falling over missing OOB error correction
    for the bootloader.
    
    This patch prevents a constant slew of (bogus) read errors reported
    by the kernel and keeping the CPU busy and fixes:
