Devices behind LPC can expose more buses (e.g. I2C on a super-i/o). So we should scan buses on LPC devices, too.

2019-07-19src: Make implicit fall throughs explicitJacob Garber
Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.

2019-07-16sb/amd/{cimx,}/sb{700,800,900}: Prevent uninitialized readsJacob Garber
There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. -- Anonymous var_num records the number of initialized entries in the reg_var array. However, this means the index of the last initialized element is one less than the value of var_num, so we need to take that into account when indexing into the array. This has already been fixed in several other places (eg. sb/amd/pi/hudson/lpc.c), so let's also do so here.

Apply commit d7b88dcb (mb/google/x86-boards: Get rid of power button device in coreboot) to AMD Brazos boards [1]: > As per the ACPI specification, there are two types of power button > devices: > 1. Fixed hardware power button > 2. Generic hardware power button > > Fixed hardware power button is added by the OSPM if POWER_BUTTON flag > is not set in FADT by the BIOS. This device has its programming model > in PM1x_EVT_BLK. All ACPI compliant OSes are expected to add this > power button device by default if the power button FADT flag is not > set. > > On the other hand, generic hardware power button can be used by > platforms if fixed register space cannot be used for the power button > device. In order to support this, power button device object with HID > PNP0C0C is expected to be added to ACPI tables. Additionally, > POWER_BUTTON flag should be set to indicate the presence of control > method for power button.

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.

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.

2015-10-24amd/sb800: Make UsbRxMode per-board customizableTobias Diedrich
On my Foxconn nT-A3500 on cold boot the board doesn't survive the soft reboot in the UsbRxMode path and the vendor bios doesn't touch this Cg2Pll voltage setting either. The fixup code for UsbRxMode in src/vendorcode/amd/cimx/sb800/SBPort.c doesn't seem to "CG PLL multiplier for USB Rx 1.1 mode", but rather lowers the Cg2Pll voltage from the hw default of 1.222V to 1.1V by setting Cg2Pll_IVR_TRIM in CGPllConfig5 to 1000. See also USB_PLL_Voltage which is only used in the UsbRxMode code path. However if this is already the efuse/eprom default for the SB800 then UsbRxMode is a no-op, so whether or not it gets executed depends on the very exact hw revision of the southbridge chip and could change between two instances of the same board. UsbRxMode used to be unitialized and was first set to default to 1 in http://review.coreboot.org/6474 (change I32237ff9, southbridge/amd/cimx/sb800: Uninitialized variables in config func): > > Why initialize those to 1? (just curious) > See src/vendorcode/amd/cimx/sb800/SBTYPE.h > git grep 'SbSpiSpeedSupport\|UsbRxMode' > src/vendorcode/amd/cimx/sb800/SBTYPE.h I could not find a corresponding errata in the SB800 errata list, however errata 15 (USB Resets Asynchronously With Port CF9h Hard Reset) might play into this being unsafe to do since the code uses CF9h to reset. So its possible that while previously undefined it still ended up defaulting to 0 and the codepath exercised on my board is simply buggy or there is a difference between a true "SB800" and the "A50 Hudson M1" presumably used on my board.
