2020-12-08	coreboot tables: Add SPI flash memory map windows to coreboot tables	Furquan Shaikh
	This change adds details about the memory map windows to translate addresses between SPI flash space and host address space to coreboot tables. This is useful for payloads to setup the translation using the decode windows already known to coreboot. Until now, there was a single decode window at the top of 4G used by all x86 platforms. However, going forward, platforms might support more decode windows and hence in order to avoid duplication in payloads this information is filled in coreboot tables. `lb_spi_flash()` is updated to fill in the details about these windows by making a call to `spi_flash_get_mmap_windows()` which is implemented by the driver providing the boot media mapping device.

2020-12-08	commonlib/region: Allow multiple windows for xlate_region_dev	Furquan Shaikh
	This change updates the translated region device (xlate_region_dev) to support multiple translation windows from the 1st address space to 2nd address space. The address spaces described by the translation windows can be non-contiguous in both spaces. This is required so that newer x86 platforms can describe memory mapping of SPI flash into multiple decode windows in order to support greater than 16MiB of memory mapped space. Since the windows can be non-contiguous, it introduces new restrictions on the region device ops - any operation performed on the translated region device is limited to only 1 window at a time. This restriction is primarily because of the mmap operation. The caller expects that the memory mapped space is contiguous, however, that is not true anymore. Thus, even though the other operations (readat, writeat, eraseat) can be updated to translate into multiple operations one for each access device, all operations across multiple windows are prohibited for the sake of consistency. It is the responsibility of the platform to ensure that any section that is operated on using the translated region device does not span multiple windows in the fmap description. One additional difference in behavior is xlate_region_device does not perform any action in munmap call. This is because it does not keep track of the access device that was used to service the mmap request. Currently, xlate_region_device is used only by memory mapped boot media on the backend. So, not doing unmap is fine. If this needs to be changed in the future, xlate_region_device will have to accept a pre-allocated space from the caller to keep track of all mapping requests.

2020-12-03	cbfs: Add verification for RO CBFS metadata hash	Julius Werner
	This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION feature. It's not useful to end-users in this stage so it cannot be selected in menuconfig (and should not be used other than for development) yet. With this patch coreboot can verify the metadata hash of the RO CBFS when it starts booting, but it does not verify individual files yet. Likewise, verifying RW CBFSes with vboot is not yet supported. Verification is bootstrapped from a "metadata hash anchor" structure that is embedded in the bootblock code and marked by a unique magic number. This anchor contains both the CBFS metadata hash and a separate hash for the FMAP which is required to find the primary CBFS. Both are verified on first use in the bootblock (and halt the system on failure). The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes to show some paths that need to be different when full protection against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For normal verification it is sufficient to check the FMAP and the CBFS metadata hash only once in the bootblock -- for TOCTOU verification we do the same, but we need to be extra careful that we do not re-read the FMAP or any CBFS metadata in later stages. This is mostly achieved by depending on the CBFS metadata cache and FMAP cache features, but we allow for one edge case in case the RW CBFS metadata cache overflows (which may happen during an RW update and could otherwise no longer be fixed because mcache size is defined by RO code). This code is added to demonstrate design intent but won't really matter until RW CBFS verification can be supported.

2020-11-21	cbfs: Add metadata cache	Julius Werner
	This patch adds a new CBFS "mcache" (metadata cache) -- a memory buffer that stores the headers of all CBFS files. Similar to the existing FMAP cache, this cache should reduce the amount of SPI accesses we need to do every boot: rather than having to re-read all CBFS headers from SPI flash every time we're looking for a file, we can just walk the same list in this in-memory copy and finally use it to directly access the flash at the right position for the file data. This patch adds the code to support the cache but doesn't enable it on any platform. The next one will turn it on by default.

2020-10-30	cbfs: Hook up to new CBFS implementation	Julius Werner
	This patch hooks coreboot up to the new commonlib/bsd CBFS implementation. This is intended as the "minimum viable patch" that makes the new implementation useable with the smallest amount of changes -- that is why some of this may look a bit roundabout (returning the whole metadata for a file but then just using that to fill out the rdevs of the existing struct cbfsf). Future changes will migrate the higher level CBFS APIs one-by-one to use the new implementation directly (rather than translated into the results of the old one), at which point this will become more efficient.

2020-10-22	drivers/smmstore: Implement SMMSTORE version 2	Patrick Rudolph
	SMMSTORE version 2 is a complete redesign of the current driver. It is not backwards-compatible with version 1, and only one version can be used at a time. Key features: * Uses a fixed communication buffer instead of writing to arbitrary memory addresses provided by untrusted ring0 code. * Gives the caller full control over the used data format. * Splits the store into smaller chunks to allow fault tolerant updates. * Doesn't provide feedback about the actual read/written bytes, just returns error or success in registers. * Returns an error if the requested operation would overflow the communication buffer. Separate the SMMSTORE into 64 KiB blocks that can individually be read/written/erased. To be used by payloads that implement a FaultTolerant Variable store like TianoCore. The implementation has been tested against EDK2 master. An example EDK2 implementation can be found here: https://github.com/9elements/edk2-1/commit/eb1127744a3a5d5c8ac4e8eb76f07e79c736dbe2 Change-Id: I25e49d184135710f3e6dd1ad3bed95de950fe057 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40520 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michał Żygowski <michal.zygowski@3mdeb.com> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com>

2020-01-28	commonlib: Add commonlib/bsd	Julius Werner
	This patch creates a new commonlib/bsd subdirectory with a similar purpose to the existing commonlib, with the difference that all files under this subdirectory shall be licensed under the BSD-3-Clause license (or compatible permissive license). The goal is to allow more code to be shared with libpayload in the future. Initially, I'm going to move a few files there that have already been BSD-licensed in the existing commonlib. I am also exracting most contents of the often-needed <commonlib/helpers.h> as long as they have either been written by me (and are hereby relicensed) or have an existing equivalent in BSD-licensed libpayload code. I am also relicensing <commonlib/compression.h> (written by me) and <commonlib/compiler.h> (same stuff exists in libpayload). Finally, I am extracting the cb_err error code definitions from <types.h> into a new BSD-licensed header so that future commonlib/bsd code can build upon a common set of error values. I am making the assumption here that the enum constants and the half-sentence fragments of documentation next to them by themselves do not meet the threshold of copyrightability.

2019-04-04	Make common macros double-evaluation safe	Julius Werner
	I just got hit by a double-evaluation bug again, it's time to attempt to fix this once more. Unfortunately there are several issues that don't make this easy: - bitfield variables don't support typeof() - local macro variables that shadow others trigger -Werror=shadow - sign warnings with integer literal and unsigned var in typeof-MIN() - ({ statement expressions }) can not be used outside functions - romcc doesn't support any of the fancy GCC/clang extensions This patch tries to address all of them as far as possible with macro magic. We don't have the technology to solve the bitfield and non-function context issues yet (__builtin_choose_expr() still throws a "no statement expression outside a function" error if it's only in the branch that's not chosen, unfortunately), so we'll have to provide alternative macros for use in those cases (and we'll avoid making __ALIGN_MASK() double-evaluation safe for now, since it would be annoying to do that there and having an alignment mask with side effects seems very unlikely). romcc can continue using unsafe versions since we're hopefully not writing a lot of new code for it. Sign warnings can be avoided in literal/variable comparisons by always using the type of the variable there. Shadowing is avoided by picking very explicit local variable names and using a special __COUNTER__ solution for MIN() and MAX() (the only ones of these you're likely to nest). Also add DIV_ROUND_UP() to libpayload since it's a generally quite useful thing to have.

As the Option ROM is no longer present in the legacy VGA area it's required for mobile platforms. On hybrid devices, like Lenovo Thinkpads supporting NVIDIA Optimus it's the only way to retrieve the Option ROM, even with legacy BIOS, as there's no PCI BAR to map.

2017-12-07	boardid: Add helpers to read sku_id strapping into coreboot tables	Julius Werner
	On many recent Chrome OS boards, the desire to unite more configurations under the same image has led to the need of a "SKU ID" that identifies different configurations of the same board (e.g. with certain optional components stuffed or not stuffed, or replaced with a comparable component). This is markedly different from the existing "board ID", because that is reserved to count "revisions" -- changes made to the same configuration over time during the development process. This patch adds support to have a mainboard define this SKU ID and pass it through the coreboot table like we already have for board IDs.

2017-12-07	boardid: Minor clean up and standardization	Julius Werner
	Merge the different coreboot table strapping ID structures into one because they're really just all the same, and I want to add more. Make the signature of the board_id() function return a uint32_t because that's also what goes in the coreboot table. Add a printk to the generic code handling strapping IDs in ramstage so that not every individual mainboard implementation needs its own print. (In turn, remove one such print from fsp1_1 code because it's in the way of my next patch.)
