2018-12-10bootcount: add a DM RTC backing store for bootcountPhilipp Tomsich
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.

2018-12-10bootcount: add uclass for bootcountPhilipp Tomsich
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>

2018-08-03bootcount: Fix misaligned cache operationAlex Kiernan
1947c2d2a0 introduces cache line flushes for the bootcounter, but if the start address is not aligned then the flush causes warnings of the form: CACHE: Misaligned operation at range [4030b7fc, 4030b83c] Align both the start and end of the buffer (possibly crossing multiple lines).

2018-07-23bootcount: flush after storing the bootcounterStefano Babic
If the bootcounter address is in a cached memory, a flush of dcache must occur after updateing the bootcounter. Issue found on i.MX6 where bootcounter is put into the internal (cached) IRAM. Signed-off-by: Stefano Babic <sbabic@denx.de>
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>

2018-02-25bootcount: Migrate CONFIG_SYS_BOOTCOUNT_ADDRTom Rini
Migrate the users of CONFIG_SYS_BOOTCOUNT_ADDR to Kconfig. We can provide a default for BOOTCOUNT_AM33XX as that's a specific part of the RTC in use. We can also provide a default for ARCH_LS1043A and ARCH_LS1021A as they had been previously calculated and their symbols are in Kconfig. In the case of other QE-enabled platforms, they are not so we must update the relevant defconfig files. The previous default only applied in some cases, even on a specific SoC family.

2013-11-11bootcount: store bootcount var in environmentHeiko Schocher
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>
2013-11-09Merge branch 'iu-boot/master' into 'u-boot-arm/master'Albert ARIBAUD
Conflicts: arch/arm/cpu/arm926ejs/mxs/Makefile board/compulab/cm_t35/Makefile board/corscience/tricorder/Makefile board/ppcag/bg0900/Makefile drivers/bootcount/Makefile include/configs/omap4_common.h include/configs/pdnb3.h Makefile conflicts are due to additions/removals of object files on the ARM branch vs KBuild introduction on the main branch. 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.
