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.

2015-10-05Add EM100 'hyper term' spi console support in ramstage & smmMartin Roth
The EM100Pro allows the debug console to be sent over the SPI bus. This is not yet working in romstage due to the use of static variables in the SPI driver code. It is also not working on chipsets that have SPI write buffers of less than 10 characters due to the 9 byte command/header length specified by the EM100 protocol. While this currently works only with the EM100, it seems like it would be useful on any logic analyzer with SPI debug - just filter on command bytes of 0x11.

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>

2015-04-14Add 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.

2014-10-07cbmem console: Locate the preram console with a symbol instead of a section.Gabe Black
On non-x86 systems, the location of the preram CBMEM console may not be in a predictable place relative to other things in the linker script. That makes it difficult to work with as its own section because the linker will complain if you try to move backwards as it lays out memory. If the console header is treated as an actual blob of memory which has to be put in the image, we'd have to predict where to put it so that it isn't before something with a lower address or after something with a higher address. Symbols, on the other hand, can be defined arbitrarily.

2014-09-15arm: Remove CAR_MIGRATE Kconfig and associated cruftJulius Werner
This is essentially a revert of commit 10bd772d. The CAR_MIGRATE mechanism is only useful to migrate variables from a special region (e.g. cache as RAM) into DRAM-backed CBMEM between different parts of the romstage (it does not persist into ramstage). Since ARM devices use SRAM for which there is no reason to become inaccessible in later parts of the romstage, this mechanism isn't useful for them. Removing it makes the romstage.ld script much simpler, which has the nice side-effect of putting the BSS at the end of the memory image (so that cbfstool can actually figure out that it doesn't need to be part of the ROM image).

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.
