treewide: Add a function to change page permissions

2025-03-14T11:37:54+00:00

For armv8 we are adding proper page permissions for the relocated U-Boot
binary. Add a weak function that can be used across architectures to change
the page permissions

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

common: Drop net.h from common header

2020-05-18T21:33:31+00:00

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

common: Move ARM cache operations out of common.h

2019-12-02T23:24:58+00:00

These functions are CPU-related and do not use driver model. Move them to
cpu_func.h

CONFIG_SPL_SYS_[DI]CACHE_OFF: add

2019-05-18T12:15:35+00:00

While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances
where these configuration items are conditional on SPL. This commit adds SPL
variants of these configuration items, uses CONFIG_IS_ENABLED(), and updates
the configurations as required.

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.

ARM: Rework and correct barrier definitions

2016-08-05T11:23:57+00:00

As part of testing booting Linux kernels on Rockchip devices, it was
discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for
some cases incomplete isb definitions.  This was causing a failure to
boot of the Linux kernel.

In order to solve this problem as well as cover any corner cases that we
may also have had a number of changes are made in order to consolidate
things.  First,  now becomes the source of isb/dsb/dmb
definitions.  This however introduces another complexity.  Due to
needing to build SPL for 32bit tegra with -march=armv4 we need to borrow
the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete
form.  Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add
a comment about it.  Now that we can always know what the target CPU is
capable off we can get always do the correct thing for the barrier.  The
final part of this is that need to be consistent everywhere and call
isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the
function names in others.
