	coreboot might not store wifi SAR values in VPD and may store it in CBFS. Logging the message with 'error' severity may interfere with automated test tool. Lowering severity to BIOS_DEBUG avoids this issue. BUG=b:171931401 BRANCH=None TEST=Severity of message is reduced and we don't see it as an error Change-Id: I5c122a57cfe92b27e0291933618ca13d8e1889ba Signed-off-by: Maulik V Vaghela <maulik.v.vaghela@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/47442 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Karthik Ramasubramanian <kramasub@google.com>

2020-10-19	volteer+vendorcode: Retrieve Cr50 version only via SPI	Jes Klinke
	No recent Chromebooks have used I2C for TPM communication, and as a result, a bug has crept in. The ability to extract Cr50 firmware string is only supported via SPI, yet code in mainboard and vendorcode attempt to do so unconditionally. This CL makes it such that the code also compiles for future designs using I2C. (Whether we want to enhance the I2C protocol to be able to provide the version string, and then implement the support is a separate question.) This effort is prompted by the desire to use reworked Volteer EVT devices for validating the new Ti50/Dauntless TPM. Dauntless will primarily be using I2C in upcoming designs.

2019-12-11	printf: Automatically prefix %p with 0x	Julius Werner
	According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

2019-08-20	src: Remove variable length arrays	Jacob 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].

	This change adds support for providing a MAC address that can be used by the OS network drivers to change the MAC address that a NIC uses. The Realtek r8152 driver in the Linux kernel supports a MAC address passthru feature which can result in the dock ethernet port using the same MAC address that is assigned to the internal NIC. This is done by calling an ACPI method at \_SB.AMAC() which returns a formatted string containing the MAC address for the dock to use. The Linux kernel implementation can be found at drivers/net/usb/r8152.c:vendor_mac_passthru_addr_read() This is implemented specifically for Chrome OS as it relies on VPD to determine the MAC address to supply. The policy which controls where the dock MAC address comes from is written into RW_VPD property "dock_passthru": "dock_mac" or empty: Use MAC address from RO_VPD value "dock_mac" "ethernet_mac0": Use MAC address from RO_VPD value "ethernet_mac0" "builtin": existing dock MAC address (return nothing) The MAC address in VPD is the standard format AA:BB:CC:DD:EE:FF and it must be converted into the string format expected by the OS which involves some string manipulation which ACPI is not great at handling.

2018-10-22	reset: Provide new single-function reset API	Nico Huber
	board_reset() replaces the existing common reset API. There is no common distinction between reset types across platforms, hence, common code could never decide which one to call. Currently only hard_reset() is used by common code. We replace these calls and provide a fall-back to the current hard_reset() implemen- tation. The fall-back will be removed along with hard_reset() after the transition of all boards.

2017-03-28	vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by default	Julius Werner
	The virtualized developer switch was invented five years ago and has been used on every vboot system ever since. We shouldn't need to specify it again and again for every new board. This patch flips the Kconfig logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the latter for Lumpy which seems to have been omitted incorrectly, and hide it from menuconfig since it's a hardware parameter that shouldn't be configurable.) Since almost all our developer switches are virtual, it doesn't make sense for every board to pass a non-existent or non-functional developer mode switch in the coreboot tables, so let's get rid of that. It's also dangerously confusing for many boards to define a get_developer_mode() function that reads an actual pin (often from a debug header) which will not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set. Therefore, this patch removes all those non-functional instances of that function. In the future, either the board has a physical dev switch and must define it, or it doesn't and must not. In a similar sense (and since I'm touching so many board configs anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC. Instead, it should just be assumed by default whenever a Chrome EC is present in the system. This way, it can also still be overridden by menuconfig.

2017-03-09	vboot/tpm2: enable nvmem commits on cr50 when writing firmware secdata	Aaron Durbin
	cr50 by default delays nvmem commits internally from the point of reset to accumulate change state. However, the factory process can put a board into dev mode through the recovery screen. This state is stored in the TPM's nvmem space. When the factory process is complete a disable_dev_request and battery_cutoff_request is performed. This leads to disabling the dev mode in TPM, but the battery is subsequently cut off so the nvmem contents never stick. Therefore, whenever antirollback_write_space_firmware() is called we know there was a change in secdata so request cr50 to immediately enable nvmem commits going forward. This allows state changes to happen immediately. The fallout from this is that when secdata is changed that current boot will take longer because every transaction that writes to TPM nvmem space will perform a write synchronously. All subsequent boots do not have that effect. It should also be noted that this approach to the implementation is a pretty severe layering violation. However, the current TPM APIs don't lend themselves well to extending commands or re-using code outside of the current routines which inherently assume all knowledge of every command (in conflict with vendor commands since those are vendor-specific by definition).

	Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.
