Quanta has asked about firmware release number signatures in FLASH.
Their standard is to use FLASH locations fffc0..fffcf for a signature line that includes the board rev number and firmware release number details below). If at all possible, they would like to use the same location and format for OLPC, as they have a lot of personnel who expect to find the info there.
Those locations appear to be unused in the LB build I'm working with, so I can't think of any reason not to accomodate them.
Here's the format: At offset f.ffc0 in FLASH: BW2 Q1A82 Q1A ------..... --- | | | | | |---First 3 characters of revision | | | |---Revision | |--- Model Revision is: Q - Manufacturer, i.e. Quanta 1 - board revision number A - Major firmware revision 82- Minor firmware revision
