# Due to limitiations in the way we load stuff, we have to avoid reusing
# memory until the kernel MMU code has taken over.

# 0x38000 is high enough to not interfere with the trap area, but low
# enough that it doesn't bump into the kernel area starting at 0x100000,
# even if the entire partition gets used as the load size by a buggy OFW.
#
# In theory 0xf0000 would work too under the current 64k size limit for
# boot1.elf defined in the HFS template, but sometimes boot1.elf is written
# directly to the PReP partition.
