Simon Glass	10f746591f	cros_ec: Add vstore support ... The EC can store small amounts of data for the benefit of the verified boot process. Since the EC is seldom reset, this can allow the AP to store data that survives a reboot or a suspend/resume cycle. Add support for this.

Simon Glass	3ae338299e	cros_ec: Show events in human-readable form ... Add a command to show the current events as a list of names. This is easier to decipher than a bit mask. Signed-off-by: Simon Glass <sjg@chromium.org>	2021-01-30 14:25:41 -07:00
Simon Glass	3a6c994f38	cros_ec: Add support for switches ... On x86 platforms the EC provides a way to read 'switches', which are on/off values determined by the EC. Add a new driver method for this and implement it for LPC. Signed-off-by: Simon Glass <sjg@chromium.org>	2021-01-30 14:25:41 -07:00
Simon Glass	8aec32f6ab	cros_ec: Support reading EC features ... The EC can support a variety of features and provides a way to find out what is available. Add support for this. Also update the feature list to the lastest available while we are here.

Simon Glass	7791df576c	cros_ec: Add support for reading the SKU ID ... This allows reading strapping pins attached to the EC. Add an implementation for this. Signed-off-by: Simon Glass <sjg@chromium.org>	2021-01-30 14:25:41 -07:00
Simon Glass	d8e9a93895	cros_ec: Add a function for the hello message ... This is used several times in this file. Put it in a function to avoid code duplication. Also add a test for this function. There are no cros_ec tests at present, so it is time to update the code. Signed-off-by: Simon Glass <sjg@chromium.org>	2021-01-30 14:25:41 -07:00
