This patch updates the EC codebase to match the suggested USB build
(20151005_041713). The spiflash utility must come from the same
tarball.
BRANCH=none
BUG=none
TEST=as follows:
- programmed the FPGA, it now reports the following when reset:
BootRom 0.8.91hw
- booted the new image using the latest spiflash version.
- disconnected the FPGA upgrade port, rebooted the device, entered
on the device console:
> spstp off
> spste
run on the workstation:
$ examples/spiraw.py -l 10 -f 800000
FT232H Future Technology Devices International, Ltd initialized at 857142 hertz
and observe on the DUT console:
Processed 10 frames rx count 11604, tx count 5512, tx_empty 10, max rx batch 11

This patch brings in the enhanced signer utility published along with
FPGA version 20150925_21715, and the image.cc file updated to fix the
bug where it was not picking up the initialized data segment from the
elf file.
The new signed image header format, among other things, describes
memory areas as read-only and read-execute, which allows the bootrom
to configure the MMU appropriately.
Makefiles had to be modified to reflect the fact that the signed image
now depends on .elf, not on .raw, and that building the signer
requires more source files. Note that some signer features are not yet
being utilized (like processing xml files describing fuses or
retrieving keys from gnubby), the source are kept for completeness.
BRANCH=none
BUG=chrome-os-partner:43791
TEST=build the cr50 image and boot in on the FPGA board using the
spiflash utility outside chroot. Observe the target starting the
console session.
