Datasheets describe the used command as 'I2C Read' but adding the word 'eeprom' in between should avoid further confusion with other block commands. Followups will add a symmetrical pair of commands i2c_block_read() and i2c_block_write() that operate via I2C_EN bit and have a 32 byte size restriction on block transfers. For some hardware revision these block commands are available, while 'I2C Read' was not.

2017-08-06sb/intel/*: Use common SMBus functionsArthur Heymans
All Intel southbridges implement the same SMBus functions. This patch replaces all these similar and mostly identical implementations with a common file. This also makes i2c block read available to all those southbridges. If the northbridge has to read a lot of SPD bytes sequentially, using this function can reduce the time being spent to read SPD five-fold.

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.

2017-04-27i82801gx: Enable PCI-to-PCI bridgeKyösti Mälkki
Once the PCI command register is written the bridge forwards future IO and memory regions, as programmed in the respective base and limit registers, to the secondary PCI bus. Since the LPC function claims the resources for IOAPIC, ROM and low IO (0x0-0xfff) in its read_resources() call, the PCI-to-PCI configuration will not overlap those regions and does not hide the resources mentioned in the original comment. The bridge was disable in the following commit [1] commit a8e1168064b34b46494b58480411a11bc98340f6 Author: Stefan Reinauer <stepan@coresystems.de> Date: Wed Mar 11 14:54:18 2009 +0000 This patch contains some significant updates to the i82801gx component and will be required for a series of later patches.

To make it more readable: * only setting to GPIO mode is made explicit; * only pins in GPIO mode are either set to input or output since this is ignored in native mode; * only output pins are set high or low, since this is read-only on input; * blink is only operational on output pins, non-blink is not set explicitly; * invert is only operational on input pins, non-invert is not set explicitly.

Don't use scratchpad registers when we have romstage_handoff to pass S3 resume flag. Scratchpad register was read too late in ramstage so acpi_is_wakeup_s3() did not evaluate correctly. This fixes low memory corruption at 0x1000-0x102c and the lack of coreboot tables (util/cbmem not working) after S3 resume. This also fixes console log from reporting early in ramstage "Normal boot" while on "S3 resume" path.
