[PATCH] Read size of installed memory from LinuxBIOS table

[Jens Freimann]

Hi,

this patch makes OFW read the size of installed RAM from the LinuxBIOS
table instead of fetching it from mem-info-pa.

With kind regards,

Jens

This nicely replaces my ugly hack. The only  2 qestions remaining are how a 
loaded Linux kernel gets the memory info: via LB-Tables or OFW devtree? 
Preferably both possible ways, I'd say. Weren't there patches on LKML ages 
ago? And the other is about memory > 4GB: lb-memsize accepts 64-bit 
addresses?

But good work nonetheless!

It would probably be a good idea to make the root node and the memory 
node have 2-cell addresses.
