2022-11-04lib/coreboot_table: Simplify API to set up lb_serialArthur Heymans
Instead of having callbacks into serial console code to set up the coreboot table have the coreboot table code call IP specific code to get serial information. This makes it easier to reuse the information as the return value can be used in a different context (e.g. when filling in a FDT). This also removes boilerplate code to set up lb_console entries by setting entry based on the type in struct lb_uart.

2022-03-15i2c: Add configurable I2C transfer timeoutJes Klinke
This patch introduces CONFIG_I2C_TRANSFER_TIMEOUT_US, which controls how long to wait for an I2C devices to produce/accept all the data bytes in a single transfer. (The device can delay transfer by stretching the clock of the ack bit.) The default value of this new setting is 500ms. Existing code had timeouts anywhere from tens of milliseconds to a full second beween various drivers. Drivers can still have their own shorter timeouts for setup/communication with the I2C host controller (as opposed to transactions with I2C devices on the bus.) In general, the timeout is not meant to be reached except in situations where there is already serious problem with the boot, and serves to make sure that some useful diagnostic output is produced on the console.

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.

2021-03-08cbfs: Pull handling of the CBFS_CACHE mem_pool into CBFS coreJulius Werner
This patch pulls control of the memory pool serving allocations from the CBFS_CACHE memlayout area into cbfs.c and makes it a core part of the CBFS API. Previously, platforms would independently instantiate this as part of boot_device_ro() (mostly through cbfs_spi.c). The new cbfs_cache pool is exported as a global so these platforms can still use it to directly back rdev_mmap() on their boot device, but the cbfs_cache can now also use it to directly make allocations itself. This is used to allow transparent decompression support in cbfs_map().

Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path.

2020-03-31security/vboot: Decouple measured boot from verified bootBill XIE
Currently, those who want to use measured boot implemented within vboot should enable verified boot first, along with sections such as GBB and RW slots defined with manually written fmd files, even if they do not actually want to verify anything. As discussed in CB:34977, measured boot should be decoupled from verified boot and make them two fully independent options. Crypto routines necessary for measurement could be reused, and TPM and CRTM init should be done somewhere other than vboot_logic_executed() if verified boot is not enabled. In this revision, only TCPA log is initialized during bootblock. Before TPM gets set up, digests are not measured into tpm immediately, but cached in TCPA log, and measured into determined PCRs right after TPM is up. This change allows those who do not want to use the verified boot scheme implemented by vboot as well as its requirement of a more complex partition scheme designed for chromeos to make use of the measured boot functionality implemented within vboot library to measure the boot process. TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

2019-11-14lib/fmap: Add optional pre-RAM cacheJulius Werner
This patch adds an optional pre-RAM cache for the FMAP which most platforms should be able to use, complementing the recently added post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP about half a dozen times from flash in verstage, which will all be coalesced into a single read with this patch. It will also help future vboot improvements since when FMAP reads become "free" vboot doesn't need to keep track of so much information separately. In order to make sure we have a single, well-defined point where the new cache is first initialized, eliminate the build-time hardcoding of the CBFS section offsets, so that all CBFS accesses explicitly read the FMAP. Add FMAP_CACHEs to all platforms that can afford it (other than the RISC-V things where I have no idea how they work), trying to take the space from things that look like they were oversized anyway (pre-RAM consoles and CBFS caches).

2019-03-21vboot: standardize on working data sizeJoel Kitching
Previously, the size of memory made for vboot_working_data through the macro VBOOT2_WORK was always specified in each individual memlayout file. However, there is effectively no reason to provide this customizability -- the workbuf size required for verifying firmware has never been more than 12K. (This could potentially increase in the future if key sizes or algorithms are changed, but this could be applied globally rather than for each individual platform.) This CL binds the VBOOT2_WORK macro to directly use the VB2_WORKBUF_RECOMMENDED_DATA_SIZE constant as defined by vboot API. Since the constant needs to be used in a linker script, we may not include the full vboot API, and must instead directly include the vb2_constants.h header.

When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2018-11-21(console,drivers/uart)/Kconfig: Fix dependenciesNico Huber
The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART, because it's using its interface. The individual UART drivers select DRIVERS_UART, because they implement the interface and depend on the common UART code. Some guards had to be fixed (using CONSOLE_SERIAL now instead of DRIVERS_UART). Some other guards that were only about compilation of units were removed. We want to build test as much as possible, right?

2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`. Patched with Coccinelle using the clumsy spatch below and some manual changes: * Nested struct initializers and one field access skipped by Coccinelle. * Removed assumption in the code that I2C_M_RD is 1. * In `i2c.h`, changed all occurences of `chip` to `slave`. @@ @@ -struct i2c_seg +struct i2c_msg @@ identifier msg; expression e; @@ ( struct i2c_msg msg = { - .read = 0, + .flags = 0, }; | struct i2c_msg msg = { - .read = 1, + .flags = I2C_M_RD, }; | struct i2c_msg msg = { - .chip = e, + .slave = e, }; ) @@ struct i2c_msg msg; statement S1, S2; @@ ( -if (msg.read) +if (msg.flags & I2C_M_RD) S1 else S2 | -if (msg.read) +if (msg.flags & I2C_M_RD) S1 ) @@ struct i2c_msg *msg; statement S1, S2; @@ ( -if (msg->read) +if (msg->flags & I2C_M_RD) S1 else S2 | -if (msg->read) +if (msg->flags & I2C_M_RD) S1 ) @@ struct i2c_msg msg; expression e; @@ ( -msg.read = 0; +msg.flags = 0; | -msg.read = 1; +msg.flags = I2C_M_RD; | -msg.read = e; +msg.flags = e ?

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

Some Chrome OS boards previously didn't have a hardcoded vboot configuration (e.g. STARTS_IN_BOOTBLOCK/_ROMSTAGE, SEPARATE_VERSTAGE, etc.) selected from their SoC and mainboard Kconfig files, and instead relied on the Chrome OS build system to pass in those options separately. Since there is usually only one "best" vboot configuration for a certain board and there is often board or SoC code specifically written with that configuration in mind (e.g. memlayout), these options should not be adjustable in menuconfig and instead always get selected by board and SoC Makefiles (as opposed to some external build system). (Removing MAINBOARD_HAS_CHROMEOS from Urara because vboot support for Pistachio/MIPS was never finished. Trying to enable even post-romstage vboot leads to weird compiler errors that I don't want to track down now. Let's stop pretending this board has working Chrome OS support because it never did.)

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.
