Add Physical Presence Check and Window Open Features

2019-11-14T14:28:02+00:00

This commit does the following: - Adds an interface to detect if physical presence has been asserted -- This happens in istep 6 -- If the window is open to detect this, it is then closed here - Adds an interface to possibly open the window to look for physical presence -- This happens in istep 10 -- It first checks to see if the window should be opened -- If the window is opened then the system shuts down to wait for physical presence to be asserted on the next power on - Adds the necessary attributes to support and test this functionality RTC:211220 Change-Id: I05a26ebad581875a4b9f2a51eb1ca3062f36c5fb Reviewed-on: http://rchgit01.rchland.ibm.com/gerrit1/84656 Reviewed-by: Ilya Smirnov Reviewed-by: Christopher J Engel Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Tested-by: Jenkins OP HW Tested-by: FSP CI Jenkins Reviewed-by: Nicholas E Bofferding

Support GPIO Physical Presence Detect Devices

2019-11-14T14:27:53+00:00

This commit makes the necessary changes to support the GPIO devices used for physical presence detection: - New attribute GPIO_INFO_PHYS_PRES - Enable GPIO Device Driver by default - GPIO Device Driver updated to support new device type - Added new GPIO PCA9551 layer to sit on top of GPIO Device Driver Change-Id: I952007503eb5d9fe873adea2eaaeccff21ae18a6 RTC:211220 Reviewed-on: http://rchgit01.rchland.ibm.com/gerrit1/84655 Reviewed-by: Ilya Smirnov Reviewed-by: Christopher J Engel Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Tested-by: Jenkins OP HW Tested-by: FSP CI Jenkins Reviewed-by: Nicholas E Bofferding

Driver changes to support i2c mux

2018-12-07T01:18:15+00:00

- Updated data structures gpioAddr_t, eeprom_addr_t, misc_args_t, nvdimm_addr_t and tpm_info_t with I2C MUX data members. Also added constructors to these structures to default there data members with the correct default info. - Updated macros DEVICE_I2C_PARMS, DEVICE_I2C_ADDRESS and DEVICE_I2C_ADDRESS_OFFSET to take the I2C MUX bus selector parameter and the I2C MUX entity path. - Added method i2cAccessMux to file i2c.H/.C that will setup the call for the I2C MUX. Method i2cCommonOP calls i2cAccessMux which then calls i2cCommonOp with appropriate parameters for the I2C MUX: i2cCommonOP -> i2cAccessMux -> i2cCommonOP. - Updated i2ctest.H with new I2C MUX params to get it to pass.

Support VDDR enable for Firestone

2015-01-22T23:17:39+00:00

- Assert GPIOs from MRW info to enable VDDR across FSP-less platforms - Updated MRW parser to parse GPIO info from MRW - Updated membuf selection algorithm to choose optimal set of GPIO enables - Defaulted GPIO_INFO attribute to invalid value - Updated GPIO device driver to use MRW i2c master path Change-Id: I0da9e0608af3e8368217c863b2606279637711e5 RTC: 117706 Reviewed-on: http://gfw160.aus.stglabs.ibm.com:8080/gerrit/14710 Tested-by: Jenkins Server Reviewed-by: A.
