bootcount: add a DM RTC backing store for bootcount 2018-12-10T09:04:45+00:00 Philipp Tomsich philipp.tomsich@theobroma-systems.com 2018-11-27T22:00:19+00:00 482734aa662fce3e0cfd0acd74db5791c514f9e2 This implements a driver using a RTC-based backing store for the DM bootcount implementation. The node configuring this feature will be compatible with 'u-boot,bootcount-rtc' and the underlying RTC device shall be reference through the property 'rtc'. An offset into the RTC device's register space can be provided through the 'offset' property. Tested on a RK3399-Q7 on a Flamingo carrier board using the SRAM area of the carrier board's RV3029 RTC.

bootcount: add uclass for bootcount 2018-12-10T09:04:44+00:00 Philipp Tomsich philipp.tomsich@theobroma-systems.com 2018-11-27T22:00:18+00:00 ebb73de1687cfd6449f492b54cc2f32b4b0ce9c5 The original bootcount methods do not provide an interface to DM and rely on a static configuration for I2C devices (e.g. bus, chip-addr, etc. are configured through defines statically). On a modern system that exposes multiple devices in a DTS-configurable way, this is less than optimal and a interface to DM-based devices will be desirable. This adds a simple driver that is DM-aware and configurable via DTS. If ambiguous (i.e. multiple bootcount-devices are present) the /chosen/u-boot,bootcount-device property can be used to select one bootcount device. Initially, this provides support for the following DM devices: * RTC devices Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Klaus Goger <klaus.goger@theobroma-systems.com>
