2018-01-30drivers/spi: support cmd opcode deduction for spi_crop_chunk()Aaron Durbin
spi_crop_chunk() currently supports deducting the command length when determining maximum payload size in a transaction. Add support for deducting just the opcode part of the command by replacing deduct_cmd_len field to generic flags field. The two enums supported drive the logic within spi_crop_chunk(): SPI_CNTRLR_DEDUCT_CMD_LEN SPI_CNTRLR_DEDUCT_OPCODE_LEN All existing users of deduct_cmd_len were converted to using the flags field.

The flag is applied here to all boards and then individually removed one at a time, as things get tested. New method is not to call AGESA internal functions directly, but via the dispatcher. AGESA call parameters are routed to hooks in both platform and board -directories, to allow for easy capture or modification as needed. For each AGESA dispatcher call made, eventlog entries are replayed to the console log. Also relocations of AGESA heap that took place are recorded.

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.

spi_crop_chunk is a property of the SPI controller since it depends upon the maximum transfer size that is supported by the controller. Also, it is possible to implement this within spi-generic layer by obtaining following parameters from the controller: 1. max_xfer_size: Maximum transfer size supported by the controller (Size of 0 indicates invalid size, and unlimited transfer size is indicated by UINT32_MAX.) 2. deduct_cmd_len: Whether cmd_len needs to be deducted from the max_xfer_size to determine max data size that can be transferred.

2016-12-23spi: Get rid of SPI_ATOMIC_SEQUENCINGFurquan Shaikh
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with the ability to perform tx and rx of flash command and response at the same time. Instead of introducing this notion at SPI flash driver layer, clean up the interface to SPI used by flash. Flash uses a command-response kind of communication. Thus, even though SPI is duplex, flash command needs to be sent out on SPI bus and then flash response should be received on the bus. Some specialized x86 flash controllers are capable of handling command and response in a single transaction. In order to support all the varied cases: 1. Add spi_xfer_vector that takes as input a vector of SPI operations and calls back into SPI controller driver to process these operations. 2. In order to accomodate flash command-response model, use two vectors while calling into spi_xfer_vector -- one with dout set to non-NULL(command) and other with din set to non-NULL(response). 3. For specialized SPI flash controllers combine two successive vectors if the transactions look like a command-response pair. 4. Provide helper functions for common cases like supporting only 2 vectors at a time, supporting n vectors at a time, default vector operation to cycle through all SPI op vectors one by one.

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.

This could probably replace the config variable completely, but I wanted to see how other people felt before doing that. I seem to recall that the value used to be calculated, so I figure that there must be a reason it's done this way at this point.

This means, vendor and southbridge directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).

2015-03-18bootstate: use structure pointers for scheduling callbacksAaron Durbin
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

An intermediate pattern was the use of u32 pointers, and division by sizeof(u32). Some of these did not get properly changed to pointer types of length 1, causing a regression in the Intel Ibex Peak SATA driver, fixed in commit 9b5f137 (Intel ibexpeak: Fix SATA configuration). Other regressions of this pattern are fixed here. I audited all changes to u32 types, and the other ones are safe.

2014-12-30drivers/pc80/mc146818rtc: Assume we always have ALTCENTURYGabe Black
This patch has a rather twisted history. It was originally split off from a chromium patch, which moved ALTCENTURY to Kconfig. However, since we have no user without ALTCENTURY, we've agreed that the best way to proceed is to eliminate the non-ALTCENTURY case entirely. The old commit message and identifiers are kept below for reference: The availability of "ALTCENTURY" is now set through a kconfig variable so it can be available to the RTC driver without having to have a specialized interface. BUG=None TEST=Built and booted on Link with the event log code modified to use the RTC interface. Verified that the event times were accurate.

To backport features introduced with recent Chromebooks and/or Intel boards in general, heavy work on the AMD AGESA platform infrastructure is required. With the AGESA PI available in binary form only, community members have little means to verify, debug and develop for the said platforms. Thus it makes sense to fork the existing agesawrapper interfaces, to give AMD PI platforms a clean and independent sandbox. New directory layout reflects the separation already taken place under 3rdparty/ and vendorcode/.

2014-10-22cmos: Rename the CMOS related functions.Gabe Black
Most of the code related to the mc146818 is not related to the RTC and is really for managing the CMOS storage. Since we intend to add a generic API for RTC drivers it's inconvenient for those functions to have an rtc_ prefix. This CL renames those functions so they start with cmos_ instead. There are some places where rtc_init was called with a comment that says something about starting the RTC. That wasn't correct before (the RTC is always running), but it looks a little odd now that the function is called cmos_init. This CL also opportunistically cleans up some style problems in this file.

2014-08-30AMD Steppe Eagle: New integrated southbridge (Avalon)Bruce Griffith
00730F01 contains the Avalon southbridge and a Platform Security Processor (PSP). Supporting the PSP requires specific binaries to be included in the ROM. The fletcher utility is used to sign PSP binaries. The IMC access routines are not accessible for newer AMD parts that use pre-compiled AGESA. Change the Hudson code such that the IMC code is not compiled if IMC is not selected in Kconfig. Disable compilation of resume.c if HAVE_ACPI_RESUME is disabled. The newer AMD mainboards will initially be released without ACPI resume support (S3) due to the use of AGESA internals in the existing Hudson routines. The Makefile change allows newer mainboards to avoid the API issues. Change Kconfig such that the FWM flag is always set for PSP-enabled parts. This has the side effect of forcing the generation of the FWM directory in the absence of GEC, IMC, and xHCI.
