Turns out I am calculating the top of DRAM incorrectly for boards
where less memory is present than the size of the lowmem region.

Could you try this please? (Apologies for the whitespace)

I think for 10 or so units per year you can actually buy
a non-mangling outgoing SMTP service if nothing else helps..

Anyways, you patch manually applied fixed most of the random
boot hangs for me, but I did see a new one after 11 boot
attempts, see below.

Regards,

Tony
