2017-05-11 | google/gru: support 800M/928M frequency for bob | Caesar Wang | |
The coreboot had no supported the different frequency for gru yet. e.g: we can't support the bob to run ddr 800M for rev3 board and run 928M for rev4 board. So, in order to support the 800M and 928M ddr frequency for bob different boards. We will use the ram_id and board_id to select the board on bob.

2017-03-07 | google/gru: add MAX_SDRAM_FREQ config to choose max ddr freq | Shunqian Zheng | |
Gru/Kevin use 933 MHz (actually 928 MHz for better jitter) as max sdram frequency, while bob uses 800 MHz. It's normal some variants can't meet 928 MHz SI requirement and hence have to use a lower freq as spec. BUG=chrome-os-partner:61001 BRANCH=gru TEST=check dpll is 800 MHz on bob Change-Id: I6d19a351f25d1f48547715ce57c3a87d9505f6f1 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 8176bfea52422c713f144ffec419752aeca66db2 Original-Change-Id: I46afba8d091f1489feeb20cafc44decaa81601fc Original-Signed-off-by: Caesar Wang <wxt@rock-chips.com> Original-Signed-off-by: Shunqian Zheng <zhengsq@rock-chips.com> Original-Reviewed-on: https://chromium-review.googlesource.com/420208 Original-Reviewed-by: Julius Werner <jwerner@chromium.org> Original-Commit-Queue: Shasha Zhao <Sarah_Zhao@asus.com> Original-Tested-by: Shasha Zhao <Sarah_Zhao@asus.com> Original-(cherry picked from commit eba5dff79eeedae5ff608d2d8d297ccf9c13cb55) Original-Reviewed-on: https://chromium-review.googlesource.com/448277 Original-Reviewed-by: Derek Basehore <dbasehore@chromium.org> Reviewed-on: https://review.coreboot.org/18581 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com> |
