2023-01-15drivers/spi/acpi: Drop 'disable_gpio_export_in_crs' flagMatt DeVillier
Exposing the GPIOs via an ACPI PowerResource and the _CRS results in the OS driver and ACPI thinking they own the GPIO. This can cause timing problems because it's not clear which system should be controlling the GPIO. There's no reason to require explicit disablement however, so drop the superfluous 'disable' flag, and change the _CRS generation to check if the GPIOs will be exported via the 'has_power_resource' flag instead. This mirrors the change made for drivers/i2c/generic. TEST=untested, as no boards selected this option.

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

For platforms using cr50, we need to support legacy pre-ready-IRQ cr50 factory images during the initial boot, so the timeout remains 100ms for I2C TPM and 10ms for SPI TPM.

The Fast Read Dual Output and Fast Read Dual I/O commands are practically identical, the only difference being how the read address is transferred (saving a whooping 2 bytes which is totally irrelevant for the amounts of data coreboot tends to read). We originally implemented Fast Read Dual Output since it's the older command and some older Winbond chips only supported that one... but it seems that some older Macronix parts for whatever reason chose to only support Fast Read Dual I/O instead. So in order to make this work for as many parts as possible, I guess we'll have to implement both. (Also, the Macronix device ID situation is utter madness with different chips with different capabilities often having the same ID, so we basically have to make a best-effort guess to strike a trade-off between fast speeds and best chance at supporting all chips. If this turns out to be a problem later, we may have to add Kconfig overrides for this or resort to SFDP parsing, although that would defeat the whole point of trying to be fast.)

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().

2021-02-15drivers/spi: Stop using a variable-length arrayAngel Pons
Only the call in `spi_flash_cmd_write_page_program` uses non-constant values for the array length. However, the value for `data_len` has an upper bound: `flash->page_size` is set to `1U << vi->page_size_shift` which depends on the flash chip vendor info, and the largest value it can currently have is 8. Thus, the maximum page size is currently 256. Define the `MAX_FLASH_CMD_DATA_SIZE` macro to place an upper bound on the amount of data that can be written in one command. Then, use this value to allocate a fixed-size buffer in `spi_flash_cmd_write`. Also, add a check to prevent buffer overflow problems. Finally, ensure that the `spi_flash_cmd_write_page_program` function always writes no more than 256 bytes of data when using the `spi_flash_cmd_write` function. Tested on Asrock B85M Pro4 (Winbond W25Q64FV), MRC cache still works.

2020-12-08coreboot tables: Add SPI flash memory map windows to coreboot tablesFurquan 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.

2020-07-02acpi_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.

2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.

2020-01-10drivers/spi/spi_flash: explicitly handle STMicro deep power stateAaron Durbin
In order to provide more consistent probing in future refactorings, pull out the release from deep sleep path in STMicro's SPI flash probing function. Call that function explicitly when RDID doesn't return anything at all. The old STMicro parts, even if supporting RDID, won't decode that instruction while in a deep power down state. Instead of re-issuing RDID after the successful wake assume the id fixup is valid.

2020-01-07drivers/spi/flashconsole: Fix shadowing local variableJohanna Schander
Commit c9b13594eb8d425e54a126b5c10e3f6fbc41528b removed the g_ prefix from global variables, leaving the local "offset" variable shadowing the global one. This commit partially reverts this by renaming one of the occations and converting the flushing logic to work on the global object.

2020-01-06drives/spi_flash: add spi_flash_cmd_write_page_program()Aaron Durbin
The SPI flashes that support page programming mode had duplicated the logic for writing in every driver. Add spi_flash_cmd_write_page_program() and use the common implementation to reduce code size that comes from duplication. The savings is ~2.5KiB per stage where the spi flash drivers are utilized.

2020-01-03drivers/spi/sst: remove unnecessary byte programmingAaron Durbin
The SST25VF064C supports page programming mode like other spi flash parts in that there isn't an offset requirement. Remove this check and single byte program because CMD_SST_BP (0x2) is the same as page programming command. Lastly, for clariy purposes provide a CMD_SST_PP to explicitly indicate page programming despite the values (0x2) being the same as byte programming for the other parts.

2019-12-11printf: Automatically prefix %p with 0xJulius 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.

These were often used to distinguish CAR_GLOBAL variables that weren't directly usable. Since we're getting rid of this special case, also get rid of the marker.

The MIPS architecture port has been added 5+ years ago in order to support a Chrome OS project that ended up going nowhere. No other board has used it since and nobody is still willing or has the expertise and hardware to maintain it. We have decided that it has become too much of a mainenance burden and the chance of anyone ever reviving it seems too slim at this point. This patch eliminates all MIPS code and MIPS-specific hacks.
