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.

2016-09-20rockchip: 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.

2016-09-20gru: Add watchdog reset supportJulius Werner
This patch adds support to reboot the whole board after a hardware watchdog reset, to avoid the usual TPM issues. Work 100% equivalent to Veyron. From my tests it looks like both SRAM and PMUSRAM get preserved across warm reboots. I'm putting the WATCHDOG_TOMBSTONE into PMUSRAM since that makes it easier to deal with in coreboot (PMUSRAM is currently not mapped as cached, so we don't need to worry about flushing the results back before reboot).

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>
