This adds SDRAM entries for the following modules: - Micron: DDMT52L256M64D2PP-107 - Hynix: H9CCNNNBKTALBR-NUD They are compatible with Samsung K4E8E324EB-EGCF, so this just copies sdram-lpddr3-samsung-2GB-24EB.inc and changes the name used in the comment near the top. Notes on our "special snowflake" boards: - veyron_danger's RAM ID is hard-coded to zero, so I skipped changes involving the binary first numbering scheme. - Rialto's SDRAM mapping is different, so I padded its SDRAM entries to 24 to match other boards. - veyron_mickey requires different MR3 and ODT settings than other boards due to its unique PCB (chrome-os-partner:43626). BUG=chrome-os-partner:59997 BRANCH=none TEST=Booted new modules on Mickey (see BUG) Change-Id: If2e22c83f4a08743f12bbc49b3fabcbf1d7d07dd Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 35cac483e86e57899dbb0898dad3510f4c2ab2d3 Original-Change-Id: I22386a25b965a4b96194d053b97e3269dbdea8c7 Original-Signed-off-by: David Hendricks <dhendrix@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/412328 Original-Reviewed-by: Stefan Reinauer <reinauer@chromium.org> Original-Commit-Queue: Jiazi Yang <Tomato_Yang@asus.com> Original-Tested-by: Jiazi Yang <Tomato_Yang@asus.com> Original-(cherry picked from commit bd5aa1a5488b99f2edc3e79951064a1f824062f6) Original-Reviewed-on: https://chromium-review.googlesource.com/446299 Original-Commit-Ready: Shunqian Zheng <zhengsq@rock-chips.com> Original-Tested-by: Shunqian Zheng <zhengsq@rock-chips.com> Original-Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-on: https://review.coreboot.org/18518 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Martin Roth <martinroth@google.com>
