Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:8967 TEST=manual While ssh'd into the device: 1) Create a test image: Extracting to: /tmp/ecup 132+1 records in 132+1 records out 136132 bytes (136 kB) copied, 0.000550122 s, 247 MB/s 2) Force the EC into its RO image: done. 3) Erase the A and B images, then reprogram them: Erasing 163840 bytes at offset 81920... done. Reading 136132 bytes from /home/chronos/user/ecb.bin... Writing to offset 81920... done. 4) Repeat step 3 about 10 times while monitoring the EC debug console. Commands should complete successfully all the time. (Note that during the flashwrite, there's a ton of debug output; what you should NOT see is something like this: WATCHDOG PC=00002104 / LR=0000597f / pSP=200013a0 Change-Id: I2f1f05eb19abcd6e19c6364f6d4ac785cca6a4c6
- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

---- chip interface ---- The interface is defined in
src/platform/ec/chip_interface/*.
+--------------------+ But the real implementation is in EC Lib.
