2020-07-06prog_loaders: Fix ramstage loading on x86Nico Huber
A regression sneaked in with 18a8ba41cc (arch/x86: Remove RELOCATABLE_ RAMSTAGE). We want to call load_relocatable_ramstage() on x86, and cbfs_prog_stage_load() on other architectures. But with the current code the latter is also called on x86 if the former succeeded. Fix that and also balance the if structure to make it more obvious. TEST=qemu-system-x86_64 boots to payload again.

2020-07-06libpayload: cbgfx: Fix add_fractions() overflow reductionJulius Werner
log2(1) is 0 and log2(0) is -1. If we have the int64_t 0xffffffff then log2(0xffffffff >> 31) = log2(0x1) = 0, so the current reduction code would not shift. That's a bad idea, though, since 0xffffffff when interpreted as an int32_t would become a negative number. We need to always shift one more than the current code does to get a safe reduction. This also means we can get rid of another compare/branch since -1 is the smallest result log2() can return, so the shift can no longer go negative now.

2020-07-03soc/intel/tigerlake: Disable hybrid storage mode in CSE Lite RO bootJamie Ryu
A UPD HybridStorageMode allows a platform to dynamically configure the PCIe strap configuration required if an Optane device is connected. The strap configuration is done by HECI commands between FSP and CSE to override the default PCIe strap value, and the updated strap value is stored in SPI RW data to be used on the next boot. CSE Lite supports the strap override when running on CSE RW partition, while CSE RO partition does not support it because CSE RO is not allowed to access SPI RW data. The strap override failure on CSE RO causes FSP not initializing PCH Clkreq and PCIe port mapping and this results NVMe and Optane initialization failure. By disabling HybridStorageMode in case of CSE RO boot, NVMe detection is done by the default PCIe configuration and Optane is detected as a single NVMe storage device on CSE RO boot in recovery mode. Both NVMe and Optane devices detection as well as OS installation to these storage devices are verified on CSE RO boot in recovery mode.

eSPI interrupts are active level high. The eSPI polarity register in the chipset inverts incoming signals if the corresonding bit is 0 in the register. Therefore, all active high (edge or level) virtual wire interrupts need to ensure they are not inverted. And really the sender of the interrupts should be conforming to the the eSPI spec. As such inverting any signals should not be necessary, but this register in the chipset allows for fixing up those misbehaviors.

2020-07-02mb/pcengines/apu1/mainboard.c: reorder includesPiotr Kleinschmidt
Originally, there was problem with PC Engines apu1 platform which returned serial number value as -64. It was caused by wrong value of dev->bus->secondary. Source of the problem is in Porting.h header file. It contains '#pragma pack(1)' which affects struct device. As mainboard.c uses different binary layout because of this attribute, reference dev->bus->secondary lands at wrong memory address. This patch reorder includes and put <AGESA.h> and <AMD.h> at the end of list, making struct device consistent. As a result bus number value in device's structure is correct and hence serial number.

This change moves the generation of I2SM ACPI device from static asl file to runtime generation by ACP device driver. dmic_select_gpio is set to match version 3+ of Trembyle and Dalboz schematics. In order to maintain backward compatibility, dmic_select_gpio is updated at runtime using variant_audio_update for board versions that are prior to version 3 of reference schematics.

2020-07-02acpi_device: Replace polarity with active_low in acpi_gpio for GpioIoFurquan Shaikh
As per ACPI spec, GpioIo does not have any polarity associated with it. Linux kernel uses `active_low` argument within GPIO _DSD property to allow BIOS to indicate if the corresponding GPIO should be treated as active low. Thus, if GPIO has active high polarity or if it does not have any polarity associated with it, then the `active_low` argument is supposed to be set to 0. Having a `polarity` field in acpi_gpio seems confusing because GPIOs might not always have polarity associated with them. Example, in case of DMIC-select GPIO where 0 means select DMIC0 and 1 means select DMIC1, there is no polarity associated with the GPIO. Thus, it would be clearer for mainboard to use macros without having to specify a particular polarity. In order to enable mainboards to provide GPIO information without polarity for GpioIo usage, this change also adds `ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

2020-07-02soc/amd/common: fix SPI bar resource usageAaron Durbin
The ACPI code was not masking off the correct bits for publishing the SPI bar to the OS. It resulted in a dmesg messagelike: system 00:00: [mem 0xfec10002-0xfec11001] has been reserved And /proc/iomem entry fec10002-fec11001 : pnp 00:00 These addresses are wrong because they are including bits of a register that are not a part of the address. Moreover, the code does not publish the eSPI register area either. The eSPI registers live at 0x10000 added to the SPI bar. Lastly, both regions are less than a page so only report a page of usage for each. Stoney Ridge's SPI bar register defines the address as 31:6 while Picasso's SPI bar register defines the address as 31:8. Use Picasso's valid mask for both cases because no one is assigning addresses that are aligned to less than 256 bytes. With the fixes, dmesg reports: system 00:00: [mem 0xfec10000-0xfec10fff] has been reserved system 00:00: [mem 0xfec20000-0xfec20fff] has been reserved And /proc/iomem indicates: fec10000-fec10fff : pnp 00:00 fec20000-fec20fff : pnp 00:00 BUG=b:160290629 Signed-off-by: Aaron Durbin <adurbin@chromium.org> Change-Id: I130b5ad26d9e13b44c25fbb35a05389f9e8841ab Reviewed-on: https://review.coreboot.org/c/coreboot/+/42959 Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2020-07-01mb/google/zork: Fix pad configurations for wake signalsFurquan Shaikh
This change updates the pad configurations for wake lines as follows: 1. Pen eject wake signal needs to be configured as PAD_WAKE i.e. wake using GPIO controller block. This is because pen eject signal is not dual routed and the trigger filtering is set by the kernel driver differently for S0 and S3 wake. Hence, it cannot use SCI GEVENT and instead has to fall back to using GPIO controller wake. 2. All other wake signals (EC, trackpad, fingerprint) need to be configured as SCI. This allows OS to enable/disable wake from these sources if required. Example: powerd disables wake from trackpad when in tablet mode. Hence, all other wake sources use SCI.

This function was copy-pasted, comments included, from Sandy Bridge. However, it is only called with 0x0044 as the northbridge's PCI ID. Therefore, `bridge_silicon_revision() & BASE_REV_MASK` will always evaluate to 0x40, which never equals `BASE_REV_SNB`, that is, 0x00. As the condition is always false, treat this code as dead and drop it. Following a similar reasoning, all direct comparisons against SNB steppings will always be true, because `bridge_silicon_revision()` returns at least 0x40 which is always larger than either `SNB_STEP_D0` or `SNB_STEP_D1`. So, drop all but the code path that is actually used.
