2021-01-20mb/siemens/{mc_apl1,...,mc_apl6}: Configure FSP-S UPDsMario Scheithauer
Until now some FSP-S parameters were configured for Siemens APL mainboards via the Binary Configuration Tool (BCT). For simplification, the original APL FSP binary should now be used. For this purpose, the corresponding FSP-S parameters are set via devicetree, respectively via mainboard_silicon_init_params accordingly. The following parameters are affected: - Disable CPU power states (C-states) - Set lowest Max Pkg Cstate - PkgC0C1 - Disable PCIe Hot Plug for all enabled RPs - Disable PCIe Transmitter Half Swing for all RPs - Disable PCIe Active State Power Management (ASPM) for all RPs - Disable PCIe L1 Substates for all RPs TEST: - Compare old with new coreboot log on mc_apl5, found no differences - Boot Linux v4.4 and check output of 'lspci' Change-Id: I5af627defd6426140cc9a74bb18db400a8971d72 Signed-off-by: Mario Scheithauer <mario.scheithauer@siemens.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/49462 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Werner Zeh <werner.zeh@siemens.com>

2019-11-12src/mainboard/siemens: Use PTN3460 chip driverUwe Poeche
This patch replaces and cleans up the redundant PTN3460 driver files in /mainboard/siemens directories by using the now available driver in src/drivers/i2c/ptn3460 and providing mainboard specific functions to the driver. TEST=Display is working on Siemens mainboards (e.g. mc_tcu3, mc_apl1, ...).

2019-04-15mb/siemens/mc_apl1: Enable HDA in devicetree for all mainboard variantsWerner Zeh
With commit '4074ce0cc7 (intel/apollolake: Add HDA to disable_dev function)' FSP is now requested to switch off HDA PCI device if it is disabled in devicetree. Doing so results in a warm restart. Normally this event will be stored in CMOS RAM (if the descriptor is configured to do so) and therefore no further resets are requested by FSP on the next boots as long as CMOS RAM is kept alive. The Siemens mainboards based on Apollo Lake do not have a CMOS battery and therefore the CMOS is not backed up. This leads to reset requests from FSP after PCI enumeration on every boot. To avoid this reset enable HDA in devicetree for these mainboards. Though we do not have any usage of HDA it should not be an issue that the HDA device is now enabled. The benefit is though that no reset is requested anymore by FSP.
