CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL allows the SoC directory to provide its own main() symbol that can execute code before the generic verstage code runs. We have now established in other places (e.g. T210 ramstage) a sort of convention that SoCs which need to run code in any stage before main() should just override stage_entry() instead. This patch aligns the verstage with that model and gets rid of the extra Kconfig option. This also removes the need for aliasing between main() and verstage(). Like other stages the main verstage code is now just in main() and can be called from stage_entry().

2016-06-12Kconfig: Set VBOOT_OPROM_MATTERS for relevant non-x86 devicesJulius Werner
The VBOOT_OPROM_MATTERS configuration option signals to vboot that the board can skip display initialization in the normal boot path. It's name is a left-over from a time when this could only happen by avoiding loading the VGA option ROM on x86 devices. Now we have other boards that can skip their native display initialization paths too, and the effect to vboot is the same. (Really, we should rename oprom_matters and oprom_loaded to display_skippable and display_initialized or something, but I don't think that's worth the amount of repositories this would need to touch.) The only effect this still has in today's vboot is to reboot and explicitly request display initialization for EC software sync on VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still, the vboot flag just declares the capability (for skipping display init), and it should be set correctly regardless of whether that actually makes a difference on a given platform (right now). This patch updates all boards/SoCs that have a conditional path based on display_init_required() accordingly.

Our EDID code had always been aligning the framebuffer's bytes_per_line (and x_resolution dependent on that) to 64.

This patch makes it explicitly configurable and depends the default on ARCH_X86 (which seems to be the simplest and least intrusive way to make it fit most cases for now... boards where this doesn't apply can still override it manually by calling edid_set_framebuffer_bits_per_pixel() again).

2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup.

2015-09-22linking: link bootblock.elf with .data and .bss sections againAaron Durbin
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. BUG=None BRANCH=None TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains the cleared bss.

Some of the Chrome OS boards were directly calling vboot called in some form after contorting around #ifdef preprocessor macros. The reasoning is that Chrome OS doesn't always do display initialization during startup. It's runtime dependent. While this is a requirement that doesn't mean vboot functions should be sprinkled around in the mainboard and chipset code. Instead provide one function, display_init_required(), that provides the policy for determining display initialization action. For Chrome OS devices this function honors vboot_skip_display_init() and all other configurations default to initializing display.

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.

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.

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.

2015-01-09tegra124: fix and fine tune the warm boot codeJoseph Lo
We assume that the clock rate of SCLK/HCLK/PCLK was 408MHz which was same as PLLP. But that is incorrect, BootROM had switched it to pllp_out2 with the rate 204MHz. So actually the warm boot procedure was running at the condition of SCLK=HCLK=PCLK=pllp_out2 with the rate 204MHz. And the CPU complex power on sequences were different with what we used in kernel and Coreboot. Fix up the sequence as below. * enable CPU clk * power on CPU complex * remove I/O clamps * remove CPU reset Update the time of the CPU complex power on function for record. * power_on_partition(PARTID_CRAIL): 528 uSec * power_on_partition(PARTID_CONC): 0 uSec * power_on_partition(PARTID_CE0): 4 uSec Finally, removing the redundant routine of a flow controller event with (20 | MSEC_EVENT | MODE_STOP).

2014-12-30i2c: Add software_i2c driver for I2C debugging and emulationJulius Werner
This patch adds I2C emulation in software through raw toggling of the SDA/SCL lines. Platforms need to provide bindings to toggle their respective I2C busses for this to work (e.g. by pinmuxing them as GPIOs, currently only enabled for Tegra). This is mostly useful as a debugging feature, to drive unusual states on a bus and closely monitor the device output without the need of a bus analyzer. It provides a few functions to "wedge" an I2C bus by aborting a transaction at certain points, which can be used to test if a system can correctly recover from an ill-timed reboot. However, it can also dynamically replace the existing I2C transfer functions and drive some/all I2C transfers on the system, which might be useful if a driver for the actual I2C controller hardware is not (yet) available. Based on original code by Doug Anderson <dianders@chromium.org> and Hung-ying Tyan <tyanh@chromium.org> for the ChromeOS embedded controller project.
