    partition device-id base 0x33000 size 0x00100
    partition os-image base 0x40000 size 0x170000

    partition user-config base 0x7c0000 size 0x10000
    partition default-config base 0x7d0000 size 0x10000
    partition log base 0x7e0000 size 0x10000
    partition radio base 0x7f0000 size 0x10000

The 'soft-version' and 'support-list' partitions are relocated afther the
'file-system' partition. This creates ones contiguous firmware area,
allowing for dynamic partition splitting.
