2018-06-14stoneyridge: Increase SMM stack size to 2KRaul E Rangel
GSMI Set Event Log is taking more than 1K in stack. This causes the stack to overflow into the adjacent stack. This has the side effect of causing any CPU waiting for the SMI handler to complete to crash when the lock is unlocked because the return pointer has been smashed. BUG=b:80539294 TEST=built on grunt and tested by running `halt` from the OS.

2018-05-18soc/amd/stoneyridge: Support ACPI USB code generationDuncan Laurie
To support generating USB devices in ACPI the platform needs to know how to determine a device name for each USB port, and for any root hubs that may be present. The AMD Stoney Ridge platform has separate controllers for USB 2.0 and USB 3.0. The USB 2.0 ports are connected through a hub to an EHCI controller while the USB 3.0 ports are directly connected to the xHCI controller. This topology is described in ACPI and the port names are exposed by the soc_acpi_name() function. The USB controllers are configured to scan for static USB devices in the devicetree and use the soc_acpi_name() function to identify them.

2018-04-23drivers/spi: reduce confusion in the APIAaron Durbin
Julius brought up confusion about the current spi api in [1]. In order alleviate the confusion stemming from supporting x86 spi flash controllers: - Remove spi_xfer_two_vectors() which was fusing transactions to accomodate the limitations of the spi controllers themselves. - Add spi_flash_vector_helper() for the x86 spi flash controllers to utilize in validating driver/controller current assumptions. - Remove the xfer() callback in the x86 spi flash drivers which will trigger an error as these controllers can't support the api.
