2015-06-12pistachio: add DDR3 initialization codeIonela Voinescu
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. It was tested on Pistachio bring up board where DDR was initialized properly and ramstage executed correctly Change-Id: I3bcbce2044327a22fce09b184d85ee11228a6b2b Signed-off-by: Ionela Voinescu <ionela.voinescu@imgtec.com> Reviewed-on: http://review.coreboot.org/10529 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2015-06-12pistachio: Use passive windowing as DQS gating schemeIonela Voinescu
Switching from active windowing DQS gating scheme to passive windowing mode resolves boot stability issues on chips found to have memory corruption issues during boot or memory tests. It was tested on Pistachio bring up board where DDR is initialized properly and ramstage executed correctly; We have cycled units over 12,000 times with no boot errors. This option was chosen over the alternative of using passive windowing mode for DQS training and after switching back to active mode, as this option was recommended by Synopsys. Using the alternative would give different timing values during training that were not longer accurate during normal activity.

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>

2015-04-22imgtec/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.

The option essentially says whether the SoC provides <soc/gpio.h> (with the interface required by the common GPIO code).

2015-04-14CBFS: Automate ROM image layout and remove hardcoded offsetsJulius Werner
Non-x86 boards currently need to hardcode the position of their CBFS master header in a Kconfig. This is very brittle because it is usually put in between the bootblock and the first CBFS entry, without any checks to guarantee that it won't overlap either of those. It is not fun to debug random failures that move and disappear with tiny alignment changes because someone decided to write "ORBC1112" over some part of your data section (in a way that is not visible in the symbolized .elf binaries, only in the final image). This patch seeks to prevent those issues and reduce the need for manual configuration by making the image layout a completely automated part of cbfstool. Since automated placement of the CBFS header means we can no longer hardcode its position into coreboot, this patch takes the existing x86 solution of placing a pointer to the header at the very end of the CBFS-managed section of the ROM and generalizes it to all architectures. This is now even possible with the read-only/read-write split in ChromeOS, since coreboot knows how large that section is from the CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be changed on systems that place other data next to coreboot/CBFS in ROM). Also adds a feature to cbfstool that makes the -B (bootblock file name) argument on image creation optional, since we have recently found valid use cases for CBFS images that are not the first boot medium of the device (instead opened by an earlier bootloader that can already interpret CBFS) and therefore don't really need a bootblock.

2015-04-09pistachio: implement timer supportVadim Bendebury
C0_COUNT register is a free running counter clocked by the CPU frequency divided by two. On the FPGA board it results in 25 MHz, on real SOCs it will have to be figured out later. Some magic addresses and numbers are used to find out if the code is running on the FPGA board. timestamp_get() and timer_monotonic_get() are kept in the same file. The CPU initialization makes sure that CO COUNT is in fact enabled and starts from zero. BRANCH=none BUG=chrome-os-partner:33595,chrome-os-partner:31438 TEST=with timer enabled, the startup code properly initializes UART and prints the coreboot bootblock banner message on the serial console.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.
