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.

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.

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>

2015-04-10tpm: Add ramstage driver and interrupt configurationDuncan Laurie
This adds a ramstage driver for the TPM and allows the interrupt to be configured in devicetree.cb. The interrupt vector is set like other PNP devices, and the interrupt polarity is set with a register configuration variable. These values are written into locality 0 TPM_INT_VECTOR and TPM_INT_ENABLE and then all interrupts are disabled so they are not used in firmware but can be enabled by the OS. It also adds an ACPI device for the TPM which will configure the reported interrupt based on what has been written into the TPM during ramstage. The _STA method returns enabled if CONFIG_LPC_TPM is enabled, and the _CRS method will only report an interrupt if one has been set in the TPM itself. The TPM memory address is added by the driver and declared in the ACPI code. In order to access it in ACPI a Kconfig entry is added for the default TPM TIS 1.2 base address. Note that IO address 0x2e is required to be declared in ACPI for the kernel driver to probe correctly.
