RE: [Bootldr] netbsd support

Joe,

I'm moving this discussion to netbsd@handhelds.org.

The bootldr was trained to boot netbsd a.out executables, but that code
has not been tested in eons. If netbsd is using a new executable
format, we'll have to add code to support it. We also need to know what
netbsd expects in terms of where the executable is loaded in dram,
whether it wants the MMU enabled and what memory mapping it wants if it
wants the MMU enabled. Do you know the answers to those questions?
