2015-07-21mec: Correct the access mode for short payloadsJagadish Krishnamoorthy
If the Host Command payload is less than 4 bytes and is word aligned then the payload was not transferred at all. EC reads the old packet and CRC mismatch occurs. In this issue, the HC command packet consisting of EC_CMD_REBOOT_EC as command and EC_REBOOT_COLD as payload encountered the same problem as above. Hence select byte access mode for shorter payloads.

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>
2015-04-29kbuild: automatically include ECsStefan Reinauer
This change switches all ECs and the generic EC ACPI code to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in ec/Makefile.inc or in ec/<vendor>/Makefile.inc. This means, vendor and ec directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).

2015-04-10cros_ec: Retry failed VBNV transactionsJulius Werner
This patch adds a few retries to NVRAM read/write transactions with the EC. Failing to read the NVRAM is not fatal to the boot, but it's still pretty bad... especially since a single initial read failure will cause vboot to blindly reinitialize the whole NVRAM with zeroes, destroying important configuration bits like dev_boot_usb. The current EC transaction timeout is one second, so the three retries added here can potentially increase boot time by three seconds per transaction... but this shouldn't happen in any normal case anyway, and if there are errors a little extra wait is probably preferrable to nuking your NVRAM. (Also, added a missing newline to an error message in the EC code.)

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.

2014-12-09spi: Factor EC protocol details out of the SPI drivers.Gabe Black
The SPI drivers for tegra and exynos5420 have code in them which waits for a frame header and leaves filler data out. The SPI driver shouldn't have support for frame headers directly. If a device uses them, it should support them itself. That makes the SPI drivers simpler and easier to write. When moving the frame handling logic into the EC support code, EC communication continued to work on tegra but no longer worked on exynos5420. That suggested the SPI driver on the 5420 wasn't working correctly, so I replaced that with the implementation in depthcharge. Unfortunately that implementation doesn't support waiting for a frame header for the EC, so these changes are combined into one. BUG=None TEST=Built and booted on pit. Built and booted on nyan.

2013-07-10ec: Add romstage function for checking and rebooting ECDuncan Laurie
Now that we are executing VbInit() in coreboot we can end up in a situation where the recovery reason is consumed during VbInit (end of romstage) and then the EC is rebooted to RO during ramstage EC init, thereby losing the recovery reason. Two possiblities are to remove the EC check+reboot from ramstage and let it happen in depthcharge. This however means that the system has to boot all the way into depthcharge and then reboot the EC and the system again. Instead if we do a check in romstage before VbInit() is called then we can reboot the EC into RO early and avoid booting all the way to depthcharge first. This change adds a ramstage version the EC init function and calls it from the shared romstage code immediately after the PCH decode windows are setup.

This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.
