Lots of changes:
Replaced LM324 and LM358 on low voltage side with TSV912 and LMV614
Adjusted dash adapter pcb to avoid ethernet port
adjusted mcp3208 and mcp23017 drivers to mirror changes from dev setup to RevA pcb
added RTC setup
changed dash light setup/gpio to active low to work with rev A hardware
added sqashfs rootfs in addition to the existing ext4 -- cuts down on boot by a little and shouldn't get corrupted
updated fuel and temperature sensor config values to work with whats on the 88 LH2.2 car I've got
fixed issue where the IL300's were oscillating -- 100n in LV side feedback
Updated Tach adapter to reflect how Rev A board was populated to get it working
updated tach adapter kernel module to add VSS input and handle extraneous pulses
2 revisions of VSS adapter board. Rev A would have been fine, but the 5V vdo regulator had the wrong pinout
started on a cold start tolerant power supply with and without load dump/reverse polarity input proection
