2016-08-02arch/riscv: Add include/arch/barrier.hJonathan Neuschäfer
mb() is used in src/arch/riscv/ and src/mainboard/emulation/*-riscv/. It is currently provided by atomic.h, but I think it fits better into barrier.h. The "fence" instruction represents a full memory fence, as opposed to variants such as "fence r, rw" which represent a partial fence. An operating system might want to use precisely the right fence, but coreboot doesn't need this level of performance at the cost of simplicity.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

2015-05-26coreboot: introduce boot_deviceAaron Durbin
The boot_device is a region_device that represents the device from which coreboot retrieves and boots its stages. The existing cbfs implementations use the boot_device as the intermediary for accessing the CBFS region. Also, there's currently only support for a read-only view of the boot_device. i.e. one cannot write to the boot_device using this view. However, a writable boot_device could be added in the future.

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>

2015-04-18kconfig: automatically include mainboardsStefan Reinauer
This change switches all mainboard vendors and mainboards to be autoincluded by Kconfig, rather than having to be mentioned explicitly. This means, vendor and mainboard directories are becoming more "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 mainboards / components to be built with a given coreboot version (given that the API did not change) Signed-off-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Change-Id: Ib68ce1478a2e12562aeac6297128a21eb174d58a Reviewed-on: http://review.coreboot.org/9295 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2015-04-17uart: pass register width in the coreboot tableVadim Bendebury
Some SOCs (like pistachio, for instance) provide an 8250 compatible UART, which has the same register layout, but mapped to a bus of a different width. Instead of adding a new driver for these controllers, it is better to have coreboot report UART register width to libpayload, and have it adjust the offsets accordingly when accessing the UART.

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. BRANCH=None BUG=None TEST=Built and booted on Veyron_Pinky, Nyan_Blaze and Falco.

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.
