2021-04-21commonlib/region: Turn addrspace_32bit into a more official APIJulius Werner
We had the addrspace_32bit rdev in prog_loaders.c for a while to help represent memory ranges as an rdev, and we've found it useful for a couple of things that have nothing to do with program loading. This patch moves the concept straight into commonlib/region.c so it is no longer anchored in such a weird place, and easier to use in unit tests. Also expand the concept to the whole address space (there's no real need to restrict it to 32 bits in 64-bit environments) and introduce an rdev_chain_mem() helper function to make it a bit easier to use. Replace some direct uses of struct mem_region_device with this new API where it seems to make sense.

2021-04-20soc/amd/{common,cezanne}: Add uPEP deviceRaul E Rangel
The uPEP device is required to support S0i3. The device has been written in ASL to make it easier to read and maintain. The device constraints are purely informational. We use a dummy constraint like the Intel platforms to keep both linux and Windows functional. In order for this device to be used by the linux kernel the ACPI_FADT_LOW_PWR_IDLE_S0 flag must be set. So including it unconditionally doesn't cause any problems. The AMD Modern Standby BIOS Implementation Guide defines two UUIDs, one for getting the device constraints, and one for handling notifications. This differs from the Intel specification and the linux driver implementation. For this reason I haven't implemented any of the notification callbacks yet.

2021-04-18soc/intel/cnl and mainboards: Drop `cnl_configure_pads()`Furquan Shaikh
CB:31250 ("soc/intel/cannonlake: Configure GPIOs again after FSP-S is done") introduced a workaround in coreboot for `soc/intel/cannonlake` platforms to save and restore GPIO configuration performed by mainboard across call to FSP Silicon Init (FSP-S). This workaround was required because FSP-S was configuring GPIOs differently than mainboard resulting in boot and runtime issues because of misconfigured GPIOs. This issue has since been fixed in FSP (verified with FSP v1263 on hatch). However, there were still 4 boards in coreboot using `cnl_configure_pads()`. As part of RFC CB:50829, librem_cnl, clevo/cml-u and system76/lemp9 were tested to ensure that this workaround is no longer required. This change drops the workaround using `cnl_configure_pads()` and updates all mainboards to use `gpio_configure_pads()` instead.

2021-04-06intel/tigerlake: Add Acoustic featuresShaunak Saha
On VCCin there was an oscillation which occurred just as the kernel started (kernel starting... message). On some devices, this behavior seems even worse. In previous platforms VCCin toggled for a few ms and then was stable. For volteer, this happens at the same point in time for around 40ms. However, it starts oscillating again later in the boot sequence. Once at the root shell, it seems to oscillate indefinitely at around 100-200Hz (very variable though). To fix this we need to control the deep C-state voltage slew rate.We have options for controlling the deep C-state voltage slew rate through FSP UPDs. This patch expose the following FSP UPD interface into coreboot: - AcousticNoiseMitigation - FastPkgCRampDisable - SlowSlewRate We are setting SlowSlewRate for all volteer boards to 2 which is Fast/8. TGL has a single VR domain(Vccin). Hence, the chip config is updated to allow mainboards to set a single value instead of an array and FSP UPDs are accordingly set.

2021-04-06soc/intel/common: Prevent SMI storm when setting SPI WPD bitAngel Pons
From Skylake/Sunrise Point onwards, there are two BIOS_CNTL registers: one on the LPC/eSPI PCI device, and another on the SPI PCI device. When the WPD bit changes from 0 to 1 and the LE bit is set, the PCH raises a TCO SMI with the BIOSWR_STS bit set. However, the BIOSWR_STS bit is not set when the TCO SMI comes from the SPI or eSPI controller instead, but a status bit in the BIOS_CNTL register gets set. If the SMI cause is not handled, another SMI will happen immediately after returning from the SMI handler, which results in a deadlock. Prevent deadlocks by clearing the SPI synchronous SMI status bit in the SMI handler. When SPI raises a synchronous SMI, the TCO_STS bit in the SMI_STS register is continously set until the SPI synchronous SMI status bit is cleared. To not risk missing any other TCO SMIs, do not clear the TCO_STS bit again in the same SMI handler invocation. If the TCO_STS bit remains set when returning from SMM, another SMI immediately happens and clears the TCO_STS bit, handling any pending events. SPI can also generate asynchronous SMIs when the WPD bit is cleared and one attempts to write to flash using SPI hardware sequencing. This patch does not account for SPI asynchronous SMIs, because they are disabled by default and cannot be enabled once the BIOS Interface Lock-Down bit in the BIOS_CNTL register has been set, which coreboot already does. These asynchronous SMIs set the SPI_STS bit of the SMI_STS register. Clearing the SPI asynchronous SMI source should be done inside the SPI_STS SMI handler, which is currently not implemented. All of this goes out of the scope of this patch, and is currently not necessary anyway. This patch does not handle eSPI because I cannot test it, and knowing if a board uses LPC or eSPI from common code is currently not possible, and this is beyond the scope of what this commit tries to achieve (fix SPI). Tested on HP 280 G2, no longer deadlocks when SMM BIOS write protection is on. Write protection will be enforced in a follow-up.

Adds a "sd_media" boot_device to allow booting from the SD card. This assumes that the generated "MLO" file is placed at a 128KB offset from the start of the SD card, to allow for the MBR etc. to be at the start of the SD card. Placing the MLO file here allows the AM335x boot ROM to load and execute the bootblock stage as well, as 128KB is one of the offsets the boot ROM checks when looking for the next stage to execute. As part of this, a FMD for the Beaglebone has also been defined. It's sized at 32M somewhat arbitrarily, as SD cards could allow for much bigger payloads. TEST: Beaglebone boots from bootblock into romstage. Romstage to ramstage still doesn't work as it needs RAM initialization first.
