Calculate the hash only of the actual RW code
No need to hash a bunch of 0xff's at the end. We explicitly set a
0xea byte after the end of the code in firmware_image.lds.S.
BUG=chrome-os-partner:11087
TEST=look for the hash start line in the EC debug output:
[0.011543 hash start 0x00014000 0x00011590]
The second number is the code size. It should be the same size as
ec.RW.bin, instead of 0x14000.
