2016-02-01drivers/pc80: Add PS/2 mouse presence detectTimothy Pearson
On certain Winbond SuperIO devices, when a PS/2 mouse is not present on the auxiliary channel both channels will cease to function if the auxiliary channel is probed while the primary channel is active. Therefore, knowledge of mouse presence must be gathered by coreboot during early boot, and used to enable or disable the auxiliary PS/2 port before control is passed to the operating system. Add auxiliary channel PS/2 device presence detect, and update the Winbond W83667HG-A driver to flag the auxiliary channel as disabled if no device was detected.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by multiple APs during startup. Calls to the nvram read functions get_option and read_option call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash controller, thus placing the SP5100 in an invalid state. This limitation is not documented in any public AMD errata, and was only discovered through considerable debugging effort.

2015-11-03drivers/pc80: Rework normal / fallback selector codeTimothy Pearson
Per IRC and Gerrit discussion, the normal / fallback selector code is a rather weak spot in coreboot, and did not function correctly for certain use cases. Rework the selector to more clearly indicate proper operation, and also remove dead code. Also tentatively abandon use of RTC bit 385; a follow-up patch will remove said bit from all affected mainboards. The correct operation of the fallback code selector approximates that of a power line recloser, with a user option to attempt normal boot that can be cleared by firmware, but never set by firmware. Additionally, if cleared by user, the fallback path should always be used on the next reboot.

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.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

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>

2015-04-10tpm: 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.

There was a large table, some members of a data structure, and a function or two which managed the timeouts and figured their value for different operations. The timeout values for the various "ordinals" were never set in the vendor specific data structure, however, and always defaulted to 2 minutes.

An issue was observed using a specific vendor's TPM in that it chokes on access to registers that are not explicitly defined in the PC client specification. The previous driver used generic access functions for reading and writing registers. However, issues come to play when reading from the status register. It read it as a 32-bit value, but that read address 0x1b which is not defined in the spec. Instead of using generic access functions for the tpm registers provide explicit ones. To that end provide more high level wrapper functions to perform the semantic access required.

2013-01-30Extend CBFS to support arbitrary ROM source media.Hung-Te Lin
Summary: Isolate CBFS underlying I/O to board/arch-specific implementations as "media stream", to allow loading and booting romstage on non-x86. CBFS functions now all take a new "media source" parameter; use CBFS_DEFAULT_MEDIA if you simply want to load from main firmware. API Changes: cbfs_find => cbfs_get_file. cbfs_find_file => cbfs_get_file_content. cbfs_get_file => cbfs_get_file_content with correct type. CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM, the ROM may come from USB, UART, or SPI -- any serial devices and not available for memory mapping. To support these devices (and allowing CBFS to read from multiple source at the same time), CBFS operations are now virtual-ized into "cbfs_media". To simplify porting existing code, every media source must support both "reading into pre-allocated memory (read)" and "read and return an allocated buffer (map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*" provides simple memory mapping simulation. Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA is defined for CBFS functions to automatically initialize a per-board default media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS function names relying on memory mapped backend (ex, "cbfs_find" => actually loads files). Now we only have two getters: struct cbfs_file *entry = cbfs_get_file(media, name); void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type); Test results: - Verified to work on x86/qemu. - Compiles on ARM, and follow up commit will provide working SPI driver.

2012-11-08RTC: Don't clear pending interrupt in resume pathDuncan Laurie
The linux kernel relies on the RTC reporting pending interrupts if the RTC alarm was used to wake the system. If we clear these flags here then the rtc-cmos driver in the kernel will think that no interrupts are pending and will not re-start the timerqueue to handle the alarm timerqueue node. This flag doesn't exist in SMM but the rtc code is compiled there. Since rtc_init() is not called by SMM it is guarded with an ifdef. I performed several thousand suspend/resume cycles without seeing an issue where hwclock was unable to read from /dev/rtc. There still is a potential kernel issue where the timerqueue can stall but this makes that much less likely to happen on resume.

2012-11-07RTC: Write build date in BCD when clearing RTC CMOSDuncan Laurie
Check the RTC on boot after RTC battery failure and ensure that the reported build date matches what is reported: > grep ^rtc /proc/driver/rtc rtc_time : 01:00:21 rtc_date : 2012-08-16 Change-Id: If23f436796754c68ae6244ef7633ff4fa0a93603 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1709 Reviewed-by: Marc Jones <marcj303@gmail.com> Tested-by: build bot (Jenkins)
2012-11-07rtc: add explicit dependency on build.hVincent Palatin
build.h is generated at build time, with highly parallel builds, we might try to compile the rtc driver too early.

2012-11-07rtc: erase CMOS memory after power failureVincent Palatin
When a power failure happens on the RTC rail, the CMOS memory (including the RTC registers) is filled with garbage. So, we erase the full first bank (112 bytes) and we reset the RTC date to the build date. To test, disconnect the CMOS battery to produce an RTC power failure, then boot the machine and observe the RTC date is the build date using "cat /sys/class/rtc/rtc0/date" Change-Id: I684bb3ad5079f96825555d4ed84dc0f7914e9884 Signed-off-by: Vincent Palatin <vpalatin@chromium.org> Reviewed-on: http://review.coreboot.org/1697 Reviewed-by: Marc Jones <marcj303@gmail.com> Tested-by: build bot (Jenkins)
2012-11-07rtc: force mc146818 register D to a correct valueVincent Palatin
On Panther Point PCH (and maybe cougar point), when some of the register D reserved bits are set, the RTC starts misbehaving (e.g. incrementing the year byte every second). There are probably undocumented features implemented behind those bits. Let's reset register D to a known state to ensure we get the expected RTC behavior.

2012-08-02RTC: Add a routine to check if the CMOS date is validzbao
If the CMOS is cleared or someone writes some random date/time on purpose, the CMOS date register has a invalid date. This will hurts some OS, like Windows 7, which hangs at MS logo forever. When we detect that, we need to write a reasonable date in CMOS. Alexandru Gagniuc: Hmm, it would be interesting to use the date the coreboot image was built and set that as the default date. At least until time travel is invented.
