2019-10-04devicetree: Fix improper use of chip_operationsKyösti Mälkki
Auto-discoverable PCI devices do not require field .enable_dev of chip_operations to be set. They are matched with PCI drivers by the use of PCI vendor and device ID fields. The name given for the chip_operations struct must match the pathname the way it is present in the devicetree.cb files. If there was no match, util/sconfig would currently choose to use the empty weak declaration it creates in static.c file.

2019-09-02drivers/vpd: add framework to search VPD in romstageJonathan Zhang
Summary: Added a framework to search VPD in romstage before memory is avilable. vpd_cbmem.c and vpd_premem.c are added for code specific for premem environment and for environment that cbmem can be used. Since global variable is forbidden in romstage. A CAR_GLOBAL variable is defined in vpd.c. This variable holds VPD binary blobs' base address and size from memory mapped flash. The overall flow is: * The CAR variable g_vpd_blob is initialized if it was not, either at romstage (before FSP-M execution in case of FSP UPD customization), or at ramstage. * At ramstage, during CBMEM_INIT, the VPD binary blob contents are copied into CBMEM. * At vpd_find() which may be called at romstage or at ramstage, it sets storage for a local struct vpd_blob variable. * The variable gets contents duplicated from g_vpd_blob, if vpd_find() is called at romstage. * The variable gets contents obtained from CBMEM, if vpd_find() is called at ramstage. Added a call vpd_get_bool(). Given a key/value pair in VPD binary blob, and name of a bool type variable, set the variable value if there is a match. Several checks are in place: * The key/value length needs to be correct. * The key name needs to match. * THe value is either '1' or '0'. Test Plan: * Build an OCP MonoLake coreboot image, flash and run.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

2019-08-13drivers/i2c/generic: Add "compatible" property to _DSDFurquan Shaikh
This change adds support for allowing devices to provide a "compatible" property string that can be used when _HID is set to PRP00001. This is used to allow Linux kernel drivers to match the device to appropriate driver based on the OF-style compatible string. Reference: https://www.kernel.org/doc/Documentation/acpi/enumeration.txt BUG=b:129162037 TEST=Verified that atmel touchscreen gets enumerated correctly on kohaku using PRP0001 and compatible string.

2019-08-11arch/x86: Flip option NO_CAR_GLOBAL_MIGRATIONKyösti Mälkki
It is easier to track CAR_GLOBAL_MIGRATION which is the approach to be deprecated with the next release. This change enforces new policy; POSTCAR_STAGE=y is not allowed together with CAR_GLOBAL_MIGRATION=y.

2019-08-08drivers/ipmi: Add option to wait for BMCPatrick Rudolph
The BMC on Supermicro X11SSH takes 34 seconds to start the IPMI KCS, but the default timeout of the IPMI KCS code is just 100 msec. Add a configurable timeout option to wait for the BMC to become ready. As it only should boot very long after power on reset, it's not a problem on reset or warm boot. Tested on Supermicro X11SSH. The IPMI driver doesn't fail with a time-out any more.

2019-08-06security/vboot: Add Support for Intel PTTChristian Walter
Add support for Intel PTT. For supporting Intel PTT we need to disable read and write access to the TPM NVRAM during the bootblock. TPM NVRAM will only be available once the DRAM is initialized. To circumvent this, we mock secdata if HAVE_INTEL_PTT is set. The underlying problem is, that the iTPM only supports a stripped down instruction set while the Intel ME is not fully booted up. Details can be found in Intel document number 571993 - Paragraph 2.10.
