| | | | | | | | | | | | | | | | | | | Add CONFIG_LTO definition to reduce the size of FW image. Modified drivers: 1. board.h: Add CONFIG_LTO definition. 2. header.c: Add __keep keyword to prevent linker ignore header during optimization.

* cleanup: Remove CDRAM / CODERAM CONFIGsShawn Nematbakhsh2015-09-161-3/+5
| | | | | | | | | | | | | | | | | | | | | | | CDRAM / CODERAM configs were previously used for chips which copied code from external SPI to program memory prior to execution, and were used inconsistently between npcx and mec1322. These CONFIGs are now completely redundant given new configs like CONFIG_MAPPED_STORAGE_BASE and CONFIG_EXTERNAL_STORAGE. BRANCH=None BUG=chrome-os-partner:23796 TEST=With entire patch series, on both Samus and Glados: - Verify 'version' EC console command is correct - Verify 'flashrom -p ec -r read.bin' reads back EC image - Verify software sync correctly flashes both EC and PD RW images Signed-off-by: Shawn Nematbakhsh <shawnn@chromium.org> Change-Id: I0e054ab4c939f9dcf54abee8e5ebd9b2e42fe9c4 Reviewed-on: https://chromium-review.googlesource.com/297804 Commit-Ready: Shawn N <shawnn@chromium.org> Tested-by: Shawn N <shawnn@chromium.org> Reviewed-by: Randall Spangler <rspangler@chromium.org>
