2018-08-14cbmem: rename vdat to chromeos_acpiJoel Kitching
There is a confusingly named section in cbmem called vdat. This section holds a data structure called chromeos_acpi_t, which exposes some system information to the Chrome OS userland utility crossystem. Within the chromeos_acpi_t structure, there is a member called vdat. This (currently) holds a VbSharedDataHeader. Rename the outer vdat to chromeos_acpi to make its purpose clear, and prevent the bizarreness of being able to access vdat->vdat.

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>

2013-04-20Eliminate use of pointers in coreboot tableStefan Reinauer
Because pointers can be 32bit or 64bit big, using them in the coreboot table requires the OS and the firmware to operate in the same mode which is not always the case. Hence, use 64bit for all pointers stored in the coreboot table. Guess we'll have to fix this up once we port to the first 128bit machines.

2013-03-22romstage: add support for vboot firmware selectionAaron Durbin
This patch implements support for vboot firmware selection. The vboot support is comprised of the following pieces: 1. vboot_loader.c - this file contains the entry point, vboot_verify_firmware(), for romstage to call in order to perform vboot selection. The loader sets up all the data for the wrapper to use. 2. vboot_wrapper.c - this file contains the implementation calling the vboot API. It calls VbInit() and VbSelectFirmware() with the data supplied by the loader. The vboot wrapper is compiled and linked as an rmodule and placed in cbfs as 'fallback/vboot'. It's loaded into memory and relocated just like the way ramstage would be. After being loaded the loader calls into wrapper. When the wrapper sees that a given piece of firmware has been selected it parses firmware component information for a predetermined number of components. Vboot result information is passed to downstream users by way of the vboot_handoff structure. This structure lives in cbmem and contains the shared data, selected firmware, VbInitParams, and parsed firwmare components. During ramstage there are only 2 changes: 1. Copy the shared vboot data from vboot_handoff to the chromeos acpi table. 2. If a firmware selection was made in romstage the boot loader component is used for the payload. Noteable Information: - no vboot path for S3. - assumes that all RW firmware contains a book keeping header for the components that comprise the signed firmware area. - As sanity check there is a limit to the number of firmware components contained in a signed firmware area. That's so that an errant value doesn't cause the size calculation to erroneously read memory it shouldn't. - RO normal path isn't supported. It's assumed that firmware will always load the verified RW on all boots but recovery. - If vboot requests memory to be cleared it is assumed that the boot loader will take care of that by looking at the out flags in VbInitParams. Built and booted. Noted firmware select worked on an image with RW firmware support. Also checked that recovery mode worked as well by choosing the RO path.

Recent changes in EC/Vboot/U-boot have completely broken the logging of developer and recovery modes. Recovery mode may not be in VBNV, so if that is zero and yet we are in recovery mode then assume it is there because the button/key was pressed. Since there may not be any actual developer mode switch we look if option rom is loaded and the system is not in recovery mode and consider that as developer mode.

2012-07-25chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared DataStefan Reinauer
coreboot used to pass some information to u-boot in the coreboot table and other information in a modified flat device tree. Since the FDT code was never upstreamed and removed from our tree, u-boot was changed to get the information it needs from the coreboot table alone. However, in the process of this change only the vboot shared data structure was passed on by coreboot, so when u-boot tried to update the ChromeOS specific ACPI entries, it would accidently overwrite the vboot data. This patch passes on the ChromeOS specific ACPI data structure instead of the vboot shared data. Another change to u-boot will teach it how to get to the vboot shared data from there.
