2018-10-09cros: Update ec_commands to latest versionSimon Glass
This file has changed quite a bit in the last 5 years as the capabilities of the ECs have grown. Sync it up with the copy in coreboot commit b9141f2215. The only change is the addition of EC_VBNV_BLOCK_SIZE_V2. This is needed because U-Boot uses the new v2 vboot API and this is not currently fully supported by Chromium OS firmware.

2018-10-09cros: Update cros_ec code to use struct udeviceSimon Glass
At present we pass around a private pointer to specify the cros_ec device. With driver model it makes more sense to pass the device. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-07-11dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()Masahiro Yamada
This function returns the pointer to the value of a node property. The current name ofnode_read_prop() is confusing. Follow the naming of_get_property() from Linux. The return type (const u32 *) is wrong. DT property values can be strings as well as integers. This is why of_get_property/fdt_getprop returns an opaque pointer.

2017-06-01cros_ec: Convert to support live treeSimon Glass
Convert this driver to support the live device tree and remove the old fdtdec support. The keyboard is not yet converted. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2016-07-11sandbox: Find keyboard driver using driver modelSimon Glass
The cros-ec keyboard is always a child of the cros-ec node. Rather than searching the device tree, looking at the children. Remove the compat string which is now unused. Signed-off-by: Simon Glass <sjg@chromium.org>

Building with gcc-5.2 raises this warning: drivers/misc/cros_ec_sandbox.c: In function cros_ec_sandbox_packet: drivers/misc/cros_ec_sandbox.c:483:5: warning: len may be used uninitialized in this function [-Wmaybe-uninitialized] if (len < 0) ^ If the function process_cmd() is called with req_hdr->command == EC_CMD_ENTERING_MODE, the value of len will be returned uninitialized.

2015-05-14sandbox: cros_ec: Support EC_CMD_ENTERING_MODE emulationSimon Glass
Emualate this function which is used with Chrome OS verified boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-18cros_ec: exynos: Match up device tree with kernel versionSimon Glass
The U-Boot device trees are slightly different in a few places. Adjust them to remove most of the differences. Note that U-Boot does not support the concept of interrupts as distinct from GPIOs, so this difference remains. For sandbox, use the same keyboard file as for ARM boards and drop the host emulation bus which seems redundant. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-18cros_ec: Drop unused CONFIG_DM_CROS_ECSimon Glass
Since all supported boards enable this option now, we can remove it along with the old code. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-16dm: core: Add dev_get_uclass_priv() to access uclass private dataSimon Glass
Add a convenience function to access the private data that a uclass stores for each of its devices. Convert over most existing uses for consistency and to provide an example for others. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-22dm: sandbox: cros_ec: Move sandbox cros_ec to driver moduleSimon Glass
Adjust the sandbox cros_ec emulation driver to work with driver model, and switch over to driver model for sandbox cros_ec. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
2014-10-22dm: cros_ec: Add support for driver modelSimon Glass
Add support for driver model if enabled. This involves minimal changes to the code, mostly just plumbing around the edges. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
2014-06-19includes: move openssl headers to include/u-bootJeroen Hofstee
commit 18b06652cd "tools: include u-boot version of sha256.h" unconditionally forced the sha256.h from u-boot to be used for tools instead of the host version. This is fragile though as it will also include the host version. Therefore move it to include/u-boot to join u-boot/md5.h etc which were renamed for the same reason. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

Add a simple emulation of the Chrome OS EC for sandbox, so that it can perform various EC tasks such as keyboard handling. Reviewed-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
