2019-03-14 | mb/google/hatch: fix RCompResistor[0] value | Shelley Chen | |
From doc#573387 CML System Memory DQ DQS Rcomp Mapping Information User Guide, RCompResistor[0] should be 121. BUG=b:122959294 BRANCH=None TEST=emerge coreboot and make sure boots up Change-Id: If69e7fb41e79d88d21b0e50fb65107a1686d696a Signed-off-by: Shelley Chen <shchen@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/31868 Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> | |||
2019-03-14 | mb/google/hatch: Use MEM_CH_SEL to indicate single_channel sku | Shelley Chen | |
MEM_CH_SEL is used to indicate whether we are on a single or dual channel device, where MEM_CH_SEL = 1 for single channel skus and MEM_CH_SEL = 0 for dual channel skus. Initialize single_channel field (from GPP_F2), which will in turn initialize MemorySpdPtr pointers in cannonlake soc code. In the first build, we did not use GPP_F2, so we need to add an internal pulldown as those early devices were all dual channel devices. BUG=b:123062346, b:122959294 BRANCH=None TEST=Boot into current boards and ensure that we have 2 channels as expected Also, verify that GPP_F2 is set to 0.
