The banked GPIO functionality in the AcpiMmio block has been consistent since the Mullins product. Move the basic support into a common directory. Each product's pin availability, MUXes, and other details must remain specific to the product. The relocated source also drops the weak configure_gevent_smi() that reports SMI is not available. The stoneyridge port relies on SMI to do its initialization, similar to modern soc/intel devices. This is the plan for future soc/amd ports, so make a missing function a build error instead of a runtime warning.

2019-05-16soc/amd/common: Create AcpiMmio functionality from stoneyridgeMarshall Dawson
Move the stoneyridge AcpiMmio code into soc/amd/common. The SB800 southbridge introduced the MMIO hardware blocks at 0xfed80000 commonly known as AcpiMmio. Implementations beginning with Mullins enable decode in PMx04. Older designs use PMx24 and allow for configuring the base address. Future work may support the older version. Comparing the documentation for AMD's RRGs and BKDGs, it is evident that the block locations have not been reassigned across products. In some cases, address locations are deprecated and new ones consumed, e.g. the early GPIO blocks were simpler at offset 0x100 and the newer GPIO banks are now at 0x1500, 0x1600, and 0x1700. Note: Do not infer the definitions within the hardware blocks are consistent across family/model products.

2019-01-21Revert "soc/amd/stoneyridge/gpio: Configure debounce for irq gpios"Raul Rangel
This reverts commit b82afce18aff24b6e5e3b73a67a6533cc4865a26. Reason for revert: This causes depthcharge to not boot due to TPM timeout errors. Because there is no wait after setting the debounce register, we lose data because the read-modify-write loses the interrupt status bit. e.g., GPIO 5 sets debounce, without a wait. Then GPIO 9 has it's debounce set. Because the interrupt controller is masking the interrupt enable status bit, the read-modify-write for GPIO9 loses the interrupt enable status bit and it never gets set again. This causes the interrupt to never latch. We should possibly make depthcharge set the interrupt enable status bit for latched GPIOs.

2019-01-16soc/amd/stoneyridge/gpio: Configure debounce for irq gpiosDaniel Kurtz
FT4 has a strange property where whenever the debounce registers for any one gpio are changed, the FT4 disables interrupt propagation for ALL gpio irqs for ~4ms. In other words, if an edge interrupt of one gpio happens exactly during this debounce-irq-off window immediately following the configuration of another gpio, the interrupt will be lost. It is quite difficult to deal with this in the kernel, since during kernel boot time, drivers & devices are probed asynchronously, meaning it may happen that an already loaded driver may miss an interrupt when some later driver is being probed and configuring its gpio interrupt. To eliminate this possibility, we pre-configure the debounce registers in ram stage for all gpios that will be used as irqs later by the kernel using the same configuration as used by the kernel, as per this table: IRQ Debounce Edge Remove Glitch Level High Preserve Low Glitch Level Low Preserve High Glitch Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> BUG=b:113880780 BRANCH=none TEST=Reboot stress test grunt (>100 times); no messages in dmesg like: tpm tpm0: Timeout waiting for TPM ready Change-Id: I94c7ecfb14e5bb209b3598e10287c80eb19da25b Reviewed-on: https://review.coreboot.org/c/30921 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin Roth <martinroth@google.com>

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.
