From cc19806ae7554edb936f729511c2041366d6775b Mon Sep 17 00:00:00 2001 From: Fabian Kunkel Date: Mon, 18 Jul 2016 17:39:28 +0200 Subject: amd/agesa/f16kb: Allow SATA Gen3 YangtzeSataResetService implements the SataSetMaxGen2 double. The value should be only set, if the condition is met. For testing, add FchParams_env->Sata.SataMode.SataSetMaxGen2 = FALSE; to your BiosCallOuts.c, which enables GEN3 for the SATA ports. Patch is tested with bap/e20xx board, Lubuntu 16.04 Kernel 4.4. $ dmesg | grep ahci #before patch ahci 0000:00:11.0: AHCI 0001.0300 32 slots 2 ports 3 Gbps 0x3 impl SATA mode $ dmesg | grep ahci #after patch ahci 0000:00:11.0: AHCI 0001.0300 32 slots 2 ports 6 Gbps 0x3 impl SATA mode Change-Id: I17a493b876a4be3236736b2116b331e465b159af Signed-off-by: Fabian Kunkel Reviewed-on: https://review.coreboot.org/15728 Tested-by: build bot (Jenkins) Reviewed-by: Nico Huber Reviewed-by: Paul Menzel --- .../agesa/f16kb/Proc/Fch/Sata/Family/Yangtze/YangtzeSataResetService.c | 1 - 1 file changed, 1 deletion(-) (limited to 'src') diff --git a/src/vendorcode/amd/agesa/f16kb/Proc/Fch/Sata/Family/Yangtze/YangtzeSataResetService.c b/src/vendorcode/amd/agesa/f16kb/Proc/Fch/Sata/Family/Yangtze/YangtzeSataResetService.c index 9b1446783e..31428990d3 100644 --- a/src/vendorcode/amd/agesa/f16kb/Proc/Fch/Sata/Family/Yangtze/YangtzeSataResetService.c +++ b/src/vendorcode/amd/agesa/f16kb/Proc/Fch/Sata/Family/Yangtze/YangtzeSataResetService.c @@ -78,7 +78,6 @@ FchInitResetSataProgram ( if ( LocalCfgPtr->SataSetMaxGen2 ) { FchSataMode |= 0x04; } - FchSataMode |= 0x04; RwPci (((SATA_BUS_DEV_FUN << 16) + 0x0A0), AccessWidth8, (UINT32)~(BIT2 + BIT3 + BIT4 + BIT5 + BIT6), 0, StdHeader); FchSataClkMode = LocalCfgPtr->SataClkMode; -- cgit v1.2.3
