2018-10-19bootcount: Make bootcount magic configurableMarek Vasut
Add new Kconfig option, SYS_BOOTCOUNT_MAGIC, to select the boot counter magic word. This can be useful ie. in case the entire boot counter register is not usable. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Tom Rini <trini@konsulko.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). Fixes: 1947c2d2a0 ("bootcount: flush after storing the bootcounter") Signed-off-by: Alex Kiernan <alex.kiernan@gmail.com> Acked-by: Stefano Babic <sbabic@denx.de>
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.

2017-07-03powerpc: remove 4xx supportHeiko Schocher
There was for long time no activity in the 4xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 4xx, so remove it. Signed-off-by: Heiko Schocher <hs@denx.de>

2012-09-01Consolidate bootcount code into drivers/bootcountStefan Roese
This patch moves all bootcount implementations into a common directory: drivers/bootcount. The generic bootcount driver is now usable not only by powerpc platforms, but others as well.
