I added CONFIG_PRAM 4 and a reserved-memory DTS node for the same space but
now u-boot complains when booting:
ERROR: reserving fdt memory region failed (addr=703ff000 size=1000)
The error is caused by arch_lmb_reserve() in arm which seem
to reserve command line and board info ?
If I remove the reserved-memory DTS node I don't get a reserved area in Linux,
don't quite understand how PRAM is supposed to work?
