Only 32MB memory available to Linux

The v1.0.5 official image reserves 32 MB of memory for something, leaving less than 32 MB remaining for Linux.

  1. For what is the 32MB memory reserved?

  2. Are there boot options I can select (via kernel arguments) to make more memory available to Linux?

Ahhh…

Be default 32MB is being reserved for the (ION) Camera subsystem.
