2017-05-05drivers/spi: Re-factor spi_crop_chunkFurquan Shaikh
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. (This is used by the amd boards.)

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.

Currently coreboot expects the loader to clear the bss section for all stages. i.e. stages don't clear their own bss. On ARM SoCs the BootROM would be responsible for this. To do that one needs to include the bss section data (all zeros) in the bootblock.bin file. This was previously being attempted by keeping the .bss info in the .data section because objcopy happened zero out non-file allocated data section data. Instead go back to linking bootblock with the bss section but mark the bss section as loadable allocatable data. That way it will be included in the binary properly when objcopy -O binary is emplyed. Also do the same for the data section in the case of no non-zero object values are in the data section. Without this change the trick of including .bss in .data was not working when there wasn't a non-zero value object in the data section.

Initialization for the Winbond W631GG6KB part using Synopsys DDR uMCTL and DDR Phy. This code adds a separate function for DDR3 initialization and moves all the necessary defines in a separate header file. The programming procedure that is executed at power up to bring up the uMCTL, PHY and memories into a state where reads and writes to the memory can be performed is the following: 1. uPCTL (Universal DDR protocol controller) initialization The timining registers TOGCNT1U, TINIT, TOGCNT100N and TRSTH needed for driving the memory power-up sequence are programmed as a function of the internal timers clock frequency. Organization (memory chip specific) values are set (column/bank/row address width and number of ranks), together with other static values (latency, timing, power up configuration). All these values are static, provided by the datasheet, being determined by the memory type, size and frequency. 2. PHY initialization The PHY is programmed with datasheet provided values, specifying the initialization values for it to send to the external memory (timing parameters). Also, delay lines (DLL) and strength of drive pads are calibrated (based on external conditions: temperature, voltage, noise) and locked. After that, the PHY goes through a trainig process (also dependent on the current conditions at boot time) to establish precise timing configuration between the DDR clock and DQS (data strobe) and between DQS and DQ (data). 3. Memory power up 4. Switch from configuration state to access state.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2015-04-29kbuild: automatically include SOCsStefan Reinauer
This change switches all SOC vendors and southbridges to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in soc/Makefile.inc or in soc/<vendor>/Makefile.inc. This means, vendor and SOC 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).

2015-04-22imgtec/pistachio: DDR reads return to controller with no bubblesIonela Voinescu
When the PHY is compiled to run in HDR(half data rate), then either NOBUB or FXDAT must be set to 1 in the DDR system general configuration register. NOBUB specifies that reads should be returned to the controller with no bubbles and this is felt preferable to the fixed latency option (FXDAT). Both of them inrease read latency.

2015-04-22imgtec/pistachio: DDR row/bank/column mappingIonela Voinescu
The DRAM configuration register, apart from holding the device density and width also has a rudimentary address mapping scheme. Currently this is set to the default Bank/Row/Column. This means that the memory is segmented into 8 chunks, each with a page detector. If all the activity is in one section of memory then the other 7 page detectors could be idle. Changing this to Row/Bank/Column would concatenate the page detectors meaning that all 8 could be used by a single initiator. This may not gain anything in a synthetic bandwidth test but could yield extra performance in a real world application or benchmark.

2015-04-22soc: select generic gpio lib on (almost) all non-x86 SOCsStefan Reinauer
BOARD_ID functionality is not what requires the GPIO lib, but it is the mainboard specific implementations that do. The option essentially says whether the SoC provides <soc/gpio.h> (with the interface required by the common GPIO code). Right now, x86 and Samsung's Exynos SOCs don't have support for this interface. So this should be selected by the SOC, not by BOARD_ID_SUPPORT.
