From 83437b2fe304599e22d0a98b5410808bcb67dc97 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Tue, 12 Nov 2013 15:45:32 +0900 Subject: altos: Allow use of internal EEPROM for config storage This stops exposing eeprom as 'storage' and instead exposes it with a separate eeprom API so that it can be used for config storage without also using it for flight log storage. The config code has been changed to allow it to either use storage for configuration data or eeprom.
