2016-09-21drivers/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.

2016-09-20Makefile.inc: Add aliases for submodule updates to gitconfig targetMartin Roth
Updating submodules seem to give people headaches, so this adds a pair of git aliases to update them. 'git sup' updates the submodules to the latest versions, but leaves any locally modified files. 'git sup-destroy' will remove the current submodules and re-initialize them. This deletes any local changes.

2016-09-20rockchip: spi: Improve SPI read efficiencySimon Glass
The SPI driver is quite slow at reading data. For example, with a 24MHz clock on gru it achieves a read speed of only 13.9Mbps. We can correct this by reading the status registers once, then reading as many bytes as are available before checking the status registers again. It seems likely that a status register read requires synchronizing with the SPI FIFO clock domain, which takes a while.

2016-09-19mainboard/google/reef: Enable cr50 TPM interruptDuncan Laurie
Enable the cr50 TPM and interrupt as GPE0_DW1_28 for use during verstage. The interrupt is left in APIC mode as the GPE is still latched when the GPIO is pulled low. BUG=chrome-os-partner:53336 Change-Id: I28ade5ee3bf08fa17d8cabf16287319480f03921 Signed-off-by: Duncan Laurie <dlaurie@chromium.org>
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.

2016-09-19soc/intel/apollolake: Add function to read and clear GPE statusDuncan Laurie
Implement the generic acpi_get_gpe() function to read and clear the GPE status for a specific GPE. Tested by watching GPE status in a loop while generating interrupts manually from the EC console.

2016-09-19soc/intel/apollolake: Initialize GPEs in bootblockDuncan Laurie
Initialize the GPEs from mainboard config in bootblock, so they can be used in verstage to query latched interrupt status. I still left it called in ramstage just to be sure that the configuration was not overwritten in FSP stages. Tested by reading and reporting GPE status in a loop in verstage and manually triggering an interrupt on EC console.

2016-09-19x86: acpi: Add function for querying GPE statusDuncan Laurie
Add a function that can be implemented by the SOC to read and clear the status of a single GPE. This can be used during firmware to poll for interrupt status. BUG=chrome-os-partner:53336 Change-Id: I536c2176320fefa4c186dabcdddb55880c47fbad Signed-off-by: Duncan Laurie <dlaurie@chromium.org>
2016-09-19drivers/i2c/tpm/cr50: Improve data handling and function namesDuncan Laurie
Unify the function names to be consistent throughout the driver and improve the handling while waiting for data available and data expected flags from the TPM. BUG=chrome-os-partner:53336 Change-Id: I7e3912fb8d8c6ad17d1af2d2a7189bf7c0c52c8e Signed-off-by: Duncan Laurie <dlaurie@chromium.org>
2016-09-19drivers/i2c/tpm/cr50: Clean up locality functionsDuncan Laurie
Clean up the mask and timeout handling in the locality functions that were copied from the original driver. BUG=chrome-os-partner:53336 Change-Id: Ifa1445224b475aec38c2ac56e15cb7ba7fcd21ea Signed-off-by: Duncan Laurie <dlaurie@chromium.org>
2016-09-19drivers/i2c/tpm/cr50: Rename i2c read/write functionsDuncan Laurie
Rename the low-level functions from iic_tpm_read/write to cr50_i2c_read/write to better match the driver name, and pass in the tpm_chip structure to the low-level read/write functions as it will be needed in future changes.
