Erasing a big section takes too long sometimes and the linux kernel driver times out, so split it up into chunks. One chunk is 1/8 of EC ROM size. Found while flashing RW on lotus: `framework_tool --flash-rw-ec ec.bin` Signed-off-by: Daniel Schaefer <[email protected]>

The whole operation should fail Signed-off-by: Daniel Schaefer <[email protected]>
If you want to simulate flashing the EC but not actually do it. Goes through all the steps to make sure the execution plan is correct. Signed-off-by: Daniel Schaefer <[email protected]>
