hdata/i2c: Fix up pci hotplug labels

2018-04-24T05:11:50+00:00

These labels are used on the devices used to do PCIe slot power control for implementing PCIe hotplug. I'm not sure how they ended up as "eeprom-pgood" and "eeprom-controller" since that doesn't make any sense. Signed-off-by: Oliver O'Halloran Signed-off-by: Stewart Smith

hdata/i2c: Ignore multi-port I2C devices

2018-04-24T05:11:50+00:00

Recent FSP firmware builds add support for multi-port I2C devices such as the GPIO expanders used for the presence detect of OpenCAPI devices and the PCIe hotplug controllers used to power cycle PCIe slots on ZZ. The OpenCAPI driver inside of skiboot currently uses a platform-specific method to talk to the relevant I2C device rather than relying on HDAT since not all platforms correctly report the I2C devices (hello Zaius). Additionally the nature of multi-port devices require that we a device specific handler so that we generate the correct DT bindings. Currently we don't and there is no immediate need for this support so just ignore the multi-port devices for now. Signed-off-by: Oliver O'Halloran Signed-off-by: Stewart Smith

hdata/i2c: Replace i2c_ prefix with dev_

2018-04-24T05:11:50+00:00

The current naming scheme makes it easy to conflate "i2cm_port" and "i2c_port." The latter is used to describe multi-port I2C devices such as GPIO expanders and multi-channel PCIe hotplug controllers. Rename i2c_port to dev_port to make the two a bit more distinct. Also rename i2c_addr to dev_addr for consistency. Signed-off-by: Oliver O'Halloran Signed-off-by: Stewart Smith

hdata/i2c: Ignore CFAM I2C master

2018-04-24T05:11:50+00:00

Recent FSP firmware builds put in information about the CFAM I2C master in addition the to host I2C masters accessible via XSCOM. Odds are this information should not be there since there's no handshaking between the FSP/BMC and the host over who controls that I2C master, but it is so we need to deal with it. This patch adds filtering to the HDAT parser so it ignores the CFAM I2C master. Without this it will create a bogus i2cm@ which migh cause issues.

hdata/slots: Apply slot label to the parent slot

2018-04-23T05:06:59+00:00

Slot names only really make sense when applied to an actual slot rather than a device. On witherspoon the GPU devices have a name associated with the device rather than the slot for the GPUs. Add a hack that moves the slot label to the parent slot rather than on the device itself. Signed-off-by: Oliver O'Halloran Signed-off-by: Stewart Smith

hdata/tpmrel: detect tpm not present by looking up the stinfo->status

2018-04-23T05:06:59+00:00

Skiboot detects if tpm is present by checking if a secureboot_tpm_info entry exists. However, if a tpm is not present, hostboot also creates a secureboot_tpm_info entry. In this case, hostboot creates an empty entry, but setting the field tpm_status to TPM_NOT_PRESENT. This detects if tpm is not present by looking up the stinfo->status. This fixes the "TPMREL: TPM node not found for chip_id=0 (HB bug)" issue, reproduced when skiboot is running on a system that has no tpm.

hdata: Add DIMM actual speed to device tree

2018-04-23T05:06:44+00:00

Recent HDAT provides DIMM actuall speed. Lets add this to device tree. Signed-off-by: Vasant Hegde [stewart: use Hz rather than Mhz, consistent with other properties] Signed-off-by: Stewart Smith

hdata: Fix DIMM size property

2018-04-23T05:02:43+00:00

Today we parse vpd blob to get DIMM size information. This is limited to FSP based system. HDAT provides DIMM size value. Lets use that to populate device tree. So that we can get size information on BMC based system as well. Signed-off-by: Vasant Hegde CC: Oliver O'Halloran Signed-off-by: Stewart Smith

hdata/spira: parse vpd to add part-number and serial-number to xscom@ node

2018-04-11T22:59:57+00:00

Expected by FWTS and associates our processor with the part/serial number, which is obviously a good thing for one's own sanity. Signed-off-by: Stewart Smith Reviewed-by: Vasant Hegde Signed-off-by: Stewart Smith
