Add conversions and mixer tests. Work in progress
Merge branch 'master' of github.com:PX4/Firmware into unit_tests
Added missing HRT functionality, cleanup
Fixed pwm limit command to behave as originally designed. The initial hold time produced random values (e.g. 40000 instead of 1500) during the INIT_TIME (0.5s) phase
Turned the mixer test into a real test, now also cross checking post mix results
Missing line break at EOF
Testing disarming and rearming as well now, removed magic numbers in favor of constants
Pruned old RAMTRON interface
Enabled EEPROM as MTD backend device
Disabling EEPROM and old RAMTRON driver
Deleting old eeprom driver directory
Patching up MPU6K pin disable defines
Introducing mtd status command, fixing compile errors for I2C setup
Merge pull request #593 from PX4/mtd_eeprom

EEPROM supported in MTD interface
Merged master into mixer unit tests branch
mtd: fixed creation and erase of a single partition
Improved test suite, now features a MTD device test
Remove outdated configs, clean up pwm limit compilation
mtd: use new MTDIOC_SETSPEED ioctl

set SPI speed to 10MHz
mtd: added "mtd readtest" and "mtd rwtest"

this allows for verification of MTD operation on startup
