Re: [PATCH V2] dtc: Basic integer expressions

Written by David Gibson [off-list ref]. Additions by me:
* Ported to ToT dtc.
* Renamed cell to integer throughout.
* Implemented value range checks.
* Allow L/UL/LL/ULL suffix on literals.
* Enabled the commented test.

v2:
* s/cell/integer/ throughout.
* Allow signed-extended values to pass the overall cell range check.
* Allow L/UL/LL/ULL suffix on literals. This is purely for compatibility
  with C, and has no effect on dtc's processing.
* Enabled the 3 disabled tests.

I'm not sure if the literal suffix handling is hacky or not...

I get this too:
