2021-01-12drivers/genesyslogic/gl9763e: Add HS400ES compatibility settingsBen Chuang
By default, the HS400 mode of GL9763E is slow mode (150MHz). Therefore, the slow mode is disabled for HS400 running at 200MHz. For eMMCs such as Hynix (H26M74002HMR) on HS400, adjust the internal Rx latch dealy of HS400 to have better compatibility.

2021-01-11drivers/genesyslogic/gl9763e: Fix boot on eMMC failed issue on VolteerRenius Chen
Booting on Kingston (EMMC64G-TA29/TX29-HP) and Hynix (H26M74002HMR) eMMC currently fails due to R/W error. This is a workaround to finetune the data latch timing by verdor-specific setting of GL9763E. For improving the compatibility of GL9763E with these two eMMC.

2020-12-10drivers/genesyslogic/gl9755: Adjust L1 exit latency to enable ASPMDuncan Laurie
Configure the CFG2 register to set the latency to <64us in order to ensure the L1 exit latency is consistent across devices and that L1 ASPM is always enabled. This moves the setup code from device init to device enable so it executes before coreboot does ASPM configuration, and removes the call to pci_dev_init() as that is just for VGA Option ROMs. BUG=b:173207454 TEST=Verify the device and link capability and control for L1: DevCap: Latency L1 <64us LnkCap: Latency L1 <64us LnkCtl: ASPM L1 Enabled Signed-off-by: Duncan Laurie <dlaurie@google.com> Change-Id: Ie2b85a6697f164fbe4f84d8cd5acb2b5911ca7a9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/47682 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
