* bootcount: add a DM SPI flash backing store for bootcountSebastian Reichel2020-11-011-0/+1
| | | | | | | This driver allows to use SPI flash as backing store for boot counter values with DM enabled. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
* bootcounter: add DM support for memory based bootcounterHeiko Schocher2020-03-161-0/+1
| | | | | | | | | | | add DM/DTS support for the memory based bootcounter in drivers/bootcount/bootcount.c. Let the old implementation in, so boards which have not yet convert to DM/DTS do not break. Signed-off-by: Heiko Schocher <hs@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
* bootcount: add a DM i2c eeprom backing store for bootcountRobert Beckett2020-01-101-0/+1
| | | | | | | This driver allows the use of i2c eeprom device or partition as backing store for boot counter values with DM enabled. Signed-off-by: Robert Beckett <bob.beckett@collabora.com>
* bootcount: add a DM RTC backing store for bootcountPhilipp Tomsich2018-12-101-0/+1
| | | | | | | | | | | | | 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 bootcountPhilipp Tomsich2018-12-101-0/+2
| | | | | | | | | | | | | | | | | | | 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>
* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-3/+1
| | | | | | | | | | | | | | | | | | | | 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>

* bootcount: store bootcount var in environmentHeiko Schocher2013-11-111-0/+1
| | | | | | | | | | | | | | | | If no softreset save registers are found on the hardware "bootcount" is stored in the environment. To prevent a saveenv on all reboots, the environment variable "upgrade_available" is introduced. If "upgrade_available" is 0, "bootcount" is always 0 therefore no need to save the environment on u-boot boot, if "upgrade_available" is 1 "bootcount" is incremented in the environment and environment gets written on u-boot start. So the Userspace Applikation must set the "upgrade_available" and "bootcount" variable to 0 (for example with fw_setenv), if a boot was successfully. Signed-off-by: Heiko Schocher <hs@denx.de>

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
