sysreset: switch to using SYSRESET_POWER_OFF for poweroff

2019-08-19T04:43:26+00:00

It seems that SYSRESET_POWER_OFF was added recently, and all previous code
used SYSRESET_POWER for poweroff. SYSRESET_POWER is supposed to be a
PMIC-level power cycle, not a poweroff.

(Comment by Simon Glass)
SYSRESET_POWER means to do a power reset (removing and reinstating all power)
SYSRESET_POWER_OFF means to turn the device off and leave it off

sandbox: Exit when SYSRESET_POWER_OFF is requested

2019-07-10T22:52:58+00:00

At present this returns but it seems better to just exit sandbox
immediately.

sandbox: sysreset: Update to support power-on reset

2018-12-05T13:01:34+00:00

If U-Boot is started from SPL or TPL, then those earlier phases deal with
the reset cause. On real hardware this cause may be lost once it is read.
Emulate that behaviour in sandbox by reporting a warm reset when a
previous phase has run since start-up.

sysreset: Add a way to find the last reset

2018-10-09T10:40:27+00:00

We have a method to return the last reset as a string for humans, but not
a method that allows it to be used programmatically. Add a new method that
returns the last reset as an enum.

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.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.
