2016-10-16soc/intel/skylake: Implement Global Reset MEI messageSubrata Banik
As per ME BWG, there are two mechanism to generate a Global Reset (resets both host and Intel ME), one is through CF9h IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set, PMC PCI offset ACh[20]. Another is to issue the Global Reset MEI message. Because any attempts to cause global reset without synchronizing the two sides might cause unwanted side effects, such as unwritten flash data that will get destroyed if the host were to cause a global reset without informing Intel ME firmware, the recommended method is to send a Global Reset MEI message when the following conditions are met: The PCH chipset firmware just needs to complete the Intel ME Interface #1 initialization and check the Intel ME HFSTS state if Intel ME is not in ERROR state and is accepting MEI commands then firmware should be able to use Global Reset MEI message to trigger global reset. Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9 write of 0x06 or 0x0E command with PCH ETR3 register bit [20] to perform the global reset.

2016-10-06rockchip: spi: Add support for 16-bit APB readsSimon Glass
With a SPI clock above about 24MHz the APB cannot keep up when doing individual byte transfers. Adjust the driver to use 16-bit reads when it can, to remove this bottleneck. Any transaction which involves writing bytes still uses 8-bit transfers, to simplify the code. These are the transfers that are not time-critical since they tend to be small. The case that really matters is reading from SPI flash. In general we can use 16-bit reads anytime we are transferring an even number of bytes. If the code detects an odd number of bytes, it tries to perform the operation in two steps: once in 16-bit mode with an even number of bytes, and once in 8-bit mode for the final byte. This allow us to use 16-bit reads even if asked to transfer (for example) 0xf423 bytes. The limit on in_now and out_now is adjusted to 0xfffe to avoid an extra transfer when transferring ~>=64KB. CQ-DEPEND=CL:383232 BUG=chrome-os-partner:56556 BRANCH=none TEST=boot on gru and see that things still work correctly.

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.

We need to set this bit i.e. bit 15 in ACPI gpe0a register at 0x430h. The Linux kernel before going to sleep checks what values are passed through ASL as wake events (through _PRW), keeps those enabled only and clears other bits in gpe0 enable registers. So we need to inform the kernel to keep gpio_tier_sci also set as these are needed for any wake event. This patch adds ASL code for sleep button device with HID id PNP0C0E.

This change modifies the lpss_i2c driver to behave more like the Linux kernel driver. In particular the controller is only enabled when processing a transaction, and is disabled after. This means that errors in one transaction will not affect later transactions. Also when disabling the controller the code is supposed to wait on the enable bit in the "enable status" register and not in the enable control register. In order to get access to this register the reg map was expanded to include all registers. This was tested with the cr50 TPM driver to ensure that if a transaction does fail that it can be successfully retried instead of the bus being unusable.

2016-09-08fsp_broadwell_de: Adjust printed address in SPI debug messagesWerner Zeh
For an unknown reason the printed address in the SPI debug messages is modified before it is printed by subtracting the constant 0xf020 from the passed in address. What I suppose this debug code should do is to print the used register address within the SPI controller while any parts of this address that belongs to the SPI base address should be omitted. To fix that remove the subtraction of 0xf020 and adjust the address mask to 0x3ff so that only the offset to the registers inside the SPI controller will be visible in the debug messages. In addition switch to uint8_t and friends over u8 to sync up with used types in this file.
