2015-10-24amd/sb800: Make UsbRxMode per-board customizableTobias Diedrich
On my Foxconn nT-A3500 on cold boot the board doesn't survive the soft reboot in the UsbRxMode path and the vendor bios doesn't touch this Cg2Pll voltage setting either. The fixup code for UsbRxMode in src/vendorcode/amd/cimx/sb800/SBPort.c doesn't seem to "CG PLL multiplier for USB Rx 1.1 mode", but rather lowers the Cg2Pll voltage from the hw default of 1.222V to 1.1V by setting Cg2Pll_IVR_TRIM in CGPllConfig5 to 1000. See also USB_PLL_Voltage which is only used in the UsbRxMode code path. However if this is already the efuse/eprom default for the SB800 then UsbRxMode is a no-op, so whether or not it gets executed depends on the very exact hw revision of the southbridge chip and could change between two instances of the same board. UsbRxMode used to be unitialized and was first set to default to 1 in http://review.coreboot.org/6474 (change I32237ff9, southbridge/amd/cimx/sb800: Uninitialized variables in config func): > > Why initialize those to 1? (just curious) > See src/vendorcode/amd/cimx/sb800/SBTYPE.h > git grep 'SbSpiSpeedSupport\|UsbRxMode' > src/vendorcode/amd/cimx/sb800/SBTYPE.h I could not find a corresponding errata in the SB800 errata list, however errata 15 (USB Resets Asynchronously With Port CF9h Hard Reset) might play into this being unsafe to do since the code uses CF9h to reset. So its possible that while previously undefined it still ended up defaulting to 0 and the codepath exercised on my board is simply buggy or there is a difference between a true "SB800" and the "A50 Hudson M1" presumably used on my board.

2012-12-12SB800: Add IMC ROM and fan control.Martin Roth
Add configuration for AMD's IMC ROM and fan registers for cimx/sb800 platforms. - Allows user to add the IMC rom to the build and to configure the location of the "signature" between the allowed positions. - Allows for no fan control, manual setup of SB800 Fan registers, or setup of the IMC fan configuration registers. - Register configuration is done through devicetree.cb. No files need to be added for new platform configuration. - Initial setup is for Persimmon, but may be extended to any cimx/sb800 platform.

2012-05-10CIMx: Allow #define LEGACY_FREE overridesMartin Roth
For legacy free AMD systems, the #define LEGACY_FREE cannot currently be overridden. This patch allows the platform_cfg.h to override that. (I know we want to get away from that, but for now...) Also allow BIOS_SIZE to be overridden on SB700 cimx based platforms.

2011-09-07AMD SB800 southbridge updateKerry She
This patch enables access to the registers of the hardware monitor logical device in the superio via isa ports 0x295/0x296. Previously this was not enabled in the SB8xx LPC device. This is required for initialisation in init_hwm() in src/superio/winbond/w83627hf/superio.c and also by OS-level sensor monitoring such as lm-sensors to access temperature, fan monitoring and control and voltage registers. asrock/e350m1 and advansus/a785e-i mainboard changes are included herein.

2011-02-14Add AMD Agesa and AMD CIMx SB800 code. Patch 1 of 8.Frank Vibrans
This code currently generates many warnings that are functionally benign. These are being addressed, but the wheels of bureaucracy turn slowly. This drop supports AMD cpu families 10h and 14h. Only Family 14h is used as an example in this set of patches. Other cpu families are supported by the infrastructure, but their specific support is not included herein. This patch is functionally independent of the other patches in this set.
