We support two FPGA images with the same firmware. To meet timing, one image has support for USB but at the cost of reducing the crypto multiplier to 8x8. The other image has full crypto but no USB support. This change displays the FPGA configuration at boot, in addition to the FPGA image version. BUG=b:25350751 BRANCH=none TEST=make buildall, manual Boot it and watch the console. You should see something like this: cr50 bootloader, 20151118_73026@80895, +USB, 8x8 crypto Valid image found at 0x00044000, jumping Change-Id: I0e5de453fcd1714fcbb170bf4364747b1e7ba894 Signed-off-by: Bill Richardson <wfrichar@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/314824 Reviewed-by: Vadim Bendebury <vbendeb@chromium.org>
