• Max out system memory by default
  
  Set the system memory to 2MiB base, 2MiB ext. This is a fully loaded 3B1
  motherboard with a RAM expansion board. 512KiB base/no ext is the minimum
  which can be specified (e.g. kernel memory map area only) but does not leave
  any room for userspace. The kernel doesn't like that and doesn't handle it
  gracefully...!

Handle memory more gracefully

• by Philip Pemberton <philpem@philpem.me.uk> [Mon, 14 Jan 2013 09:48:21 +0000] rev 119
• Handle memory more gracefully
  
  Fixed in this cset:
  
  * Return an 'empty space' value if the memory wraps around
  
  * Allow the 'empty bus' value to be changed via an ifdef
  
  * Properly handle situations where expansion memory is turned off
