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.

To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

This was added to handle cases of Intel FSP platforms that had EARLY_CBMEM_INIT but could not migrate CAR variables to CBMEM. These boards were recently fixed. To support combination of EARLY_CBMEM_INIT without CAR migration was added maintenance effort with little benefits. You had no CBMEM console for romstage and the few timestamps you could store were circulated via PCI scratchpads or CMOS nvram.

We have to live with this for now, until microcode is moved to blobs for all CPUs, at which point we may adjust Kconfig accordingly.

I didn't see any documentation that actually said that this location was free to use, and didn't need to be restored after use in S3 resume, but it looks like the DOS boot vector gets loaded juat above this location, so it SHOULD be ok. The alternative is to copy the memory out and store it in cbmem until we're ready to restore it. 2) When a request for the pointer to a CAR variable comes in, pass back the location inside the FSP hob structure. 3) Skip the memcopy of the CAR Data. The CAR variables do not get transitioned back into cbmem, but used out of the HOB structure. 4) Remove the BROKEN_CAR_MIGRATE Kconfig option from the FSP platform.

2015-01-27vboot2: add verstageStefan Reinauer
This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e and fixes the build issue that cuased it to be reverted. Verstage will host vboot2 for firmware verification. It's a stage in the sense that it has its own set of toolchains, compiler flags, and includes. This allows us to easily add object files as needed. But it's directly linked to bootblock. This allows us to avoid code duplication for stage loading and jumping (e.g. cbfs driver) for the boards where bootblock has to run in a different architecture (e.g. Tegra124). To avoid name space conflict, verstage symbols are prefixed with verstage_. TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

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.

2014-12-30ipq/arm: Redesign hooks for bootblockVadim Bendebury
The following patches had to be squashed to properly build all the different ARM boards. ipq8064: storm: re-arrange bootblock initialization The recent addition of the storm bootblock initialization broke compilation of Exynos platforms. The SOC specific code needs to be kept in the respective source files, not in the common CPU code. As of now coreboot does not provide a separate SOC initialization API. In general it makes sense to invoke SOC initialization from the board initialization code, as the board knows what SOC it is running on. Presently all what's need initialization on 8064 is the timer. This patch adds the SOC initialization framework for 8064 and moves there the related code. BUG=chrome-os-partner:27784 TEST=manual . nyan_big, peach_pit, and storm targets build fine now.

Experience has shown that nearly every board needs either one or both of these hooks, so having explicit Kconfigs for them has become unwieldy. Instead, this patch implements them as a weak symbol that can be overridden by mainboard/SoC code, as the more recent arm64_soc_init() is also doing. Since the whole concept of a single "CPU" on ARM systems has kinda died out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had already been done on Storm/ipq806x, which is now adjusted to directly use the generic hook.) Also add a proper license header to bootblock_common.h that was somehow missing. Leaving non-ARM32 architectures out for now, since they are still using the really old and weird x86 model of directly including a file. These architectures should also eventually be aligned with the cleaner ARM32 model as they mature. BRANCH=None BUG=chrome-os-partner:32123 TEST=Booted on Pinky.

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.

2014-12-15x86: Set BOOT_MEDIA_SPI_BUSDavid Hendricks
BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based platforms to set up CBFS media. It turns out it can also be helpful for setting up the eventlog which is intended to reside on the same SPI flash as CBFS. Setting it for x86 will allow us to remove an assumption about which SPI bus is used for this flash device. Long term this can go away as we come up with a better abstraction for the eventlog's backing store. This is only intended to help us get from here to there.
