2015-05-26acpi: Remove monolithic ACPIVladimir Serbinenko
All boards now use per-device ACPI. This patch finishes migration by removing transitional kludges.

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>

2015-04-17Fix non-x86 __PRE_RAM__ assertions and add FATAL_ASSERTS Kconfig optionJulius Werner
This patch fixes a bug that caused non-x86 boards to use the poor man's assert() version with a lot more instructions per invocation and hexadecimal line numbers in __PRE_RAM__ environments. This was really just an oversight in the ARM port... even x86 uses a proper printk() in most cases (those with CAR) and there's no reason not to do so on the generally even more flexible SRAM-based architectures. Additionally, it adds a new Kconfig option to make failed assertions and BUG() calls halt again. This seems to have been the original intention, but was commented out once out of fear that this might prevent production systems from booting. It is still a useful debugging feature though (since otherwise assertions can easily just scroll past and get overlooked), so the user should be able to decide the this based on his needs.

2015-04-17rk3288: Handle framebuffer through memlayout, not the resource systemJulius Werner
We've traditionally tucked the framebuffer at the end of memory (above CBMEM) on ARM and declared it reserved through coreboot's resource allocator. This causes depthcharge to mark this area as reserved in the kernel's device tree, which may be necessary to avoid display corruption on handoff but also wastes space that the OS could use instead. Since rk3288 boards now have proper display shutdown code in depthcharge, keeping the framebuffer memory reserved across the handoff (and thus throughout the lifetime of the system) should no longer be necessary. For now let's just switch the rk3288 implementation to define it through memlayout instead, which is not communicated through the coreboot tables and will get treated as normal memory by depthcharge. Note that this causes it to get wiped in developer/recovery mode, which should not be a problem because that is done in response to VbInit() (long before any images are drawn) and 0 is the default value for a corebootfb anyway (a black pixel). Eventually, we might want to think about adding more memory types to coreboot's resource system (e.g. "reserved until kernel handoff", or something specifically for the frame buffer) to model this situation better, and maybe merge it with memlayout somehow.

Coreboot is designed to have a single serial console at most, on top of that it may have a CBMEM (virtual) console. Matters are complicated by the fact that console interface is different between bootblock and later stages. A linker list of console driver descriptors is used to allow to determine the set and type of console drivers at compile time. Even though the upstream seems to have done away with this approach, which does not seem the best idea. As an alternative this patch introduces a common wrapper which different UART drivers can plug in into. The driver exports a single API which can be used both directly (in bootblock) and through the wrapper (in later stages). The existing drivers can be adjusted to fit this scheme one by one. The common UART driver API also aligns fine with the upstream approach.

2015-04-14timer: Reestablish init_timer(), consolidate timer initialization callsJulius Werner
We have known for a while that the old x86 model of calling init_timer() in ramstage doesn't make sense on other archs (and is questionable in general), and finally removed it with CL:219719. However, now timer initialization is completely buried in the platform code, and it's hard to ensure it is done in time to set up timestamps. For three out of four non-x86 SoC vendors we have brought up for now, the timers need some kind of SoC-specific initialization. This patch reintroduces init_timer() as a weak function that can be overridden by platform code. The call in ramstage is restricted to x86 (and should probably eventually be removed from there as well), and other archs should call them at the earliest reasonable point in their bootblock. (Only changing arm for now since arm64 and mips bootblocks are still in very early state and should sync up to features in arm once their requirements are better understood.) This allows us to move timestamp_init() into arch code, so that we can rely on timestamps being available at a well-defined point and initialize our base value as early as possible. (Platforms who know that their timers start at zero can still safely call timestamp_init(0) again from platform code.) BRANCH=None BUG=None TEST=Booted Pinky, Blaze and Storm, compiled Daisy and Pit.

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.

2015-04-10gpio: Remove non-ternary tristate mode, make ternaries easierJulius Werner
The function to read board IDs from tristate GPIOs currently supports two output modes: a normal base-3 integer, or a custom format where every two bits represent one tristate pin. Each board decides which representation to use on its own, which is inconsistent and provides another possible gotcha to trip over when reading unfamiliar code. The two-bits-per-pin format creates the additional problem that a complete list of IDs (such as some boards use to build board-ID tables) necessarily has "holes" in them (since 0b11 does not correspond to a possible pin state), which makes them extremely tricky to write, read and expand. It's also very unintuitive in my opinion, although it was intended to make it easier to read individual pin states from a hex representation. This patch switches all boards over to base-3 and removes the other format to improve consistency. The tristate reading function will just print the pin states as they are read to make it easier to debug them, and we add a new BASE3() macro that can generate ternary numbers from pin states. Also change the order of all static initializers of board ID pin lists to write the most significant bit first, hoping that this can help clear up confusion about the endianness of the pins. CQ-DEPEND=CL:219902 BUG=None TEST=Booted on a Nyan_Blaze (with board ID 1, unfortunately the only one I have).

2015-04-10gpio: Extend common GPIO header, simplify function namesJulius Werner
We've had gpiolib.h which defines a few common GPIO access functions for a while, but it wasn't really complete. This patch adds the missing gpio_output() function, and also renames the unwieldy gpio_get_in_value() and gpio_set_out_value() to the much easier to handle gpio_get() and gpio_set(). The header is renamed to the simpler gpio.h while we're at it (there was never really anything "lib" about it, and it was presumably just chosen due to the IPQ806x include/ conflict problem that is now resolved). It also moves the definition of gpio_t into SoC-specific code, so that different implementations are free to encode their platform-specific GPIO parameters in those 4 bytes in the most convenient way (such as the rk3288 with a bitfield struct). Every SoC intending to use this common API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most 4 bytes in length. Files accessing the API only need to include <gpio.h> which may pull in additional things (like a gpio_t creation macro) from <soc/gpio.h> on its own. For now the API is still only used on non-x86 SoCs. Whether it makes sense to expand it to x86 as well should be separately evaluated at a later point (by someone who understands those systems better). Also, Exynos retains its old, incompatible GPIO API even though it would be a prime candidate, because it's currently just not worth the effort.

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.

It also renames __BOOT_BLOCK__ and __VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency. This change is intended to provide finer control and clearer communication of intent after we added a new (optional) stage that falls under __PRE_RAM__, and will hopefully provide some robustness for the future (we don't want to end up always checking for romstage with #if defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) && !defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The __PRE_RAM__ macro stays as it is since many features do in fact need to differentiate on whether RAM is available. (Some also depend on whether RAM is available at the end of a stage, in which case #if !defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be authoritative.) It's unfeasable to change all existing occurences of __PRE_RAM__ that would be better described with __ROMSTAGE__, so this patch only demonstratively changes a few obvious ones in core code.

2015-04-03program loading: add prog_run() functionAaron Durbin
The prog_run() function abstracts away what is required for running a given program. Within it, there are 2 calls: 1. platform_prog_run() and 2. arch_prog_run(). The platform_prog_run() allows for a chipset to intercept a program that will be run. This allows for CPU switching as currently needed in t124 and t132.

2015-04-03program loading: introduce struct progAaron Durbin
The struct prog serves as way to consolidate program loading. This abstraction can be used to perform more complicated execution paths such as running a program on a separate CPU after it has been loaded. Currently t124 and t132 need to do that in the boot path. Follow on patches will allow the platform to decide how to execute a particular program. Note: the vboot path is largely untouched because it's already broken in the coreboot.org tree. After getting all the necessary patches pushed then vboot will be fixed.

2015-04-02vpd: retrieve mac addresses and pass them to bootloaderVadim Bendebury
Chrome OS devices firmware usually includes an area called VPD (Vital Product Data). VPD is a blob of a certain structure, in particular containing freely defined variable size fields. A field is a tuple of the field name and field contents. MAC addresses of the interfaces are stored in VPD as well. Field names are in the form of 'ethernet_macN', where N is the zero based interface number. This patch retrieves the MAC address(es) from the VPD and populates them in the coreboot table so that they become available to the bootloader. BUG=chrome-os-partner:32152, chromium:417117 TEST=with this and other patches in place the storm device tree shows up with MAC addresses properly initialized.

Two weak functions were added so that architecture specific operations on each segment of payload or stage can be performed. Each architecture must define its own operations, otherwise the behavior will default to do-nothing functions. This patch has been updated by to fit more in line with how program loading is currently being done. The API is the same as the original, but all call sites to stages/payloads have been updated. This is known to break any archs that use rmodule loading that needs cache maintenance. That will be fixed in a forthcoming patch. Also, the vboot paths are left as is for easier upstreaming of the rest of the vboot patches.

The three states are - external pull down (interpreted as 0) - external pull up (1) - not connected (2) This has been required by Nvidia devices so far, but Exynos and Ipq8086 platforms need this too. This patch moves the function reading the tertiary state into the library and exposes the necessary GPIO API functions in a new include file. The functions are still supposed to be provided by platform specific modules. The function interpreting the GPIO states has been modified to allow to interpret the state either as a true tertiary number or as a set two bit fields. Since linker garbage collection is not happening when building x86 targets, a new configuration option is being added to include the new module only when needed. BUG=chrome-os-partner:30489 TEST=verified that nyan_big still reports proper revision ID.

2015-03-21timer: add stopwatch constructAaron Durbin
There's a lot of places where expiration and running time are open coded. Allow for those places to be simplified by adding a stopwatch construct. The stopwatch can have an expiration or just be used to accumulate time. BUG=None TEST=Built and verified API works as expected by using implementation.

2015-03-20loaders: add run_romstage() function to bootblockAaron Durbin
Provide a common run_romstage() function to be used by bootblocks to load and run romstage. This is similar to run_ramstage() in that it provides a single entry point for doing the necessary work of loading and running romstage.
