Hi!

Does FreeBSD support 36bit physical addressing?
I have P4080 board with 4G RAM.
Trying to boot using ubldr I hit into zero size of MR_ATTR_DRAM memory
region in ubldr ub_get_sys_info() because u64 value in u-boot does not fit
into unsigned long of mem_region.size. Temporary fix this by
decrementing size of DRAM in u-boot.
Now ubldr load kernel from NFS and after  "Kernel entry at
0x1001000..."  I have nothing.
I suppose current kernel implementation does not support 36bit
addressing and hang during initial configuration.
