bootcount: Fix misaligned cache operation

2018-08-03T23:53:54+00:00

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")

bootcount: flush after storing the bootcounter

2018-07-23T07:55:20+00:00

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.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

bootcount: Migrate CONFIG_SYS_BOOTCOUNT_ADDR

2018-02-25T18:41:54+00:00

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.
