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.

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.

2016-09-14lpss_i2c: Change handling of controller enable/disableDuncan Laurie
This change modifies the lpss_i2c driver to behave more like the Linux kernel driver. In particular the controller is only enabled when processing a transaction, and is disabled after. This means that errors in one transaction will not affect later transactions. Also when disabling the controller the code is supposed to wait on the enable bit in the "enable status" register and not in the enable control register. In order to get access to this register the reg map was expanded to include all registers. This was tested with the cr50 TPM driver to ensure that if a transaction does fail that it can be successfully retried instead of the bus being unusable.

2016-07-01skylake: Generate ACPI timing values for I2C devicesDuncan Laurie
Have the Skylake SOC generate ACPI timing values for the enabled I2C controllers instead of passing it in the DSDT with static timings. The timing values are generated from the controller clock speed and are more accurate than the hardcoded values that were in the ASL which were originally copied from Broadwell where the controller is running at a different clock speed... Additionally it is now possible for a board to override the values using devicetree.cb. If zero is passed in for SCL HCNT or LCNT then the kernel will generate its own timing using the same forumla, but if the SDA hold time value is zero the kernel will NOT generate a correct value and the SDA hold time may be incorrect. This was tested on the Chell platform to ensure all the I2C devices on the board are still operational with these new timing values.
