2016-09-19Revert "drivers/i2c/tpm/cr50: Support interrupts for status"Duncan Laurie
This reverts commit a5e419c51187d24818f056327746a18676fe3a20.
2016-09-19drivers/i2c/tpm/cr50: Support interrupts for statusDuncan Laurie
Support reading the ACPI GPE status (on x86) to determine when the cr50 is ready to return response data or is done processing written data. If the interrupt is not defined by Kconfig then it will continue to use the safe delay. This was tested with reef hardware and a modified cr50 image that generates interrupts at the intended points.

2016-09-19drivers/i2c/tpm: Split cr50 driver from main driverDuncan Laurie
Originally I thought it would be cleaner to keep this code in one place, but as things continue to diverge it ends up being easier to split this into its own driver. This way the different drivers in coreboot, depthcharge, and the kernel, can all be standalone and if one is changed it is easier to modify the others. This change splits out the cr50 driver and brings along the basic elements from the existing driver with no real change in functionality. The following commits will modify the code to make it consistent so it can all be shared with depthcharge and the linux kernel drivers.

2016-09-14drivers/i2c/tpm: Clean up handling of command readyDuncan Laurie
The TPM driver was largely ignoring the meaning of the command ready bit in the status register, instead just arbitrarily sending it at the end of every receive transaction. Instead of doing this have the command ready bit be set at the start of a transaction, and only clear it at the end of a transaction if it is still set, in case of failure. Also the cr50 function to wait for status and burst count was not waiting the full 2s that the existing driver does so that value is increased. Also, during the probe routine a delay is inserted after each status register read to ensure the TPM has time to actually start up.

2016-09-06drivers/i2c/tpm: Add support for cr50 TPMDuncan Laurie
Add support for the cr50 TPM used in apollolake chromebooks. This requires custom handling due to chip limitations, which may be revisited but are needed to get things working today. - timeouts need to be longer - must use the older style write+wait+read read protocol - all 4 bytes of status register must be read at once - same limitation applies when reading burst count from status reg - burst count max is 63 bytes, and burst count behaves slightly differently than other I2C TPMs - TPM expects the host to drain the full burst count (63 bytes) from the FIFO on a read Luckily the existing driver provides most abstraction needed to make this work seamlessly. To maximize code re-use the support for cr50 is added directly instead of as a separate driver and the style is kept similar to the rest of the driver code. This was tested with the cr50 TPM on a reef board with vboot use of TPM for secdata storage and factory initialization.

2016-08-25vboot: consolidate google_chromeec_early_init() callsAaron Durbin
On x86 platforms, google_chromeec_early_init() is used to put the EC into RO mode when there's a recovery request. This is to avoid training memory multiple times when the recovery request is through an EC host event while the EC is running RW code. Under that condition the EC will be reset (along with the rest of the system) when the kernel verification happens. This leads to an execessively long recovery path because of the double reboot performing full memory training each time. By putting this logic into the verstage program this reduces the bootblock size on the skylake boards. Additionally, this provides the the correct logic for all future boards since it's not tied to FSP nor the mainboard itself. Lastly, this double memory training protection works only for platforms which verify starting from bootblock. The platforms which don't start verifying until after romstage need to have their own calls (such as haswell and baytrail).

Coupled with the unknown ordering of boot_device_init() being called this can lead to unexpected behavior (probing failures or hangs). Instead move the act of initializing the SPI flash boot device to when the various infrastructure requires its usage when it calls boot_device_rw(). Those platforms utilizing the RW boot device would need to ensure their SPI drivers are functional and ready when the call happens.

2016-08-19lib/cbfs_spi: provide boot_device_rw() supportAaron Durbin
Provide the RW boot device operations for the common cbfs SPI wrapper. The RW region_device is the same as the read-only one. As noted in the boot_device_rw() introduction patch the mmap() support should not be used in conjuction with writing as that results in incoherent operations. That's fine as the current mmap() support is only used in the cbfs layer which does not support writing, i.e. no cbfs regions would be written to with any previous or outstanding mmap() calls.

2016-08-19Kconfig: introduce writable boot device notionAaron Durbin
Indicate to the build system that a platform provides support for a writable boot device. The following will provide the necessary support: COMMON_CBFS_SPI_WRAPPER users soc/intel/apollolake soc/intel/baytrail soc/intel/braswell soc/intel/broadwell soc/intel/skylake The SPI_FLASH option is auto-selected if the platform provides write supoprt for the boot device and SPI flash is the boot device. Other platforms may provide similar support, but they do that in a device specific manner such as selecting SPI_FLASH explicitly. This provides clearance against build failures where chipsets don't provide SPI API implementations even though the platform may use a SPI flash to boot.

2016-08-19drivers/spi: move cbfs_spi.c locationAaron Durbin
The common boot device spi implementation is very much specific to SPI flash. As such it should be moved into that subdirectory. It's still a high-level option but it correctly depends on BOOT_DEVICE_SPI_FLASH. Additionally that allows the auto-selection of SPI_FLASH by a platform selecting COMMON_CBFS_SPI_WRAPPER which allows for culling of SPI_FLASH selections everywhere.

2016-08-18Kconfig: lay groundwork for not assuming SPI flash boot deviceAaron Durbin
Almost all boards and chipsets within the codebase assume or use SPI flash as the boot device. Therefore, provide an option for the boards/chipsets which don't currently support SPI flash as the boot device. The default is to assume SPI flash is the boot device unless otherwise instructed. This falls in line with the current assumptions, but it also allows one to differentiate a platform desiring SPI flash support while it not being the actual boot device. One thing to note is that while google/daisy does boot with SPI flash part no SPI API interfaces were ever implemented. Therefore, mark that board as not having a SPI boot device.

2016-08-15drivers/spi: provide option to not include all flash driversAaron Durbin
All flash drivers are automatically included in the build unless COMMON_CBFS_SPI_WRAPPER was selected. However, there are cases where these drivers are unnecessary such as certain intel platforms where spi controller uses hardware sequencing without any ability to manually probe the device. Therefore, provide an option that the SoC can set the default value for. The COMMON_CBFS_SPI_WRAPPER option is still honored by not including all drivers when that is selected.
