2016-11-29Hook up libhwbase in ramstageNico Huber
It's hidden behind a configuration option `CONFIG_RAMSTAGE_LIBHWBASE`. This also adds some glue code to use the coreboot console for debug output and our monotonic timer framework as timer backend. v2: Also update 3rdparty/libhwbase to the latest master commit.

2016-10-02Kconfig: Update default hex values to start with 0xMartin Roth
Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.

2016-03-23arch/x86: introduce postcar stage/phaseAaron Durbin
Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

2015-04-14Add console wrapper for UART driverVadim Bendebury
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.

2015-04-06New 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.

2015-03-10console/Kconfig: Enable CBMEM console by defaultPaul Menzel
Currently on AMD boards no romstage messages can be saved in CBMEM, so only messages from ramstage on will be stored in CBMEM. Other than that nothing changes. Enabling CBMEM console by default does not noticeably decrease boot time as the messages are directly written to CAR or RAM. The board status script under `util/board_status/` reads the coreboot messages from CBMEM, which are then uploaded to the board status repository. With CBMEM console disabled by default, currently no coreboot console messages are uploaded to the board status repository, although it is important to have those. Enabling CBMEM console by default improves this situation, so that for all boards at least ramstage messages are stored in the board status repository.

Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can do CBMEM console in bootblock and romstage. Kconfig forces it to zero if _BASE is unset or we cannot do CAR migration on x86. Add CBMEM console to bootblock, except for x86. Only one of bootblock and romstage clears the pre-RAM buffer.
