2025-03-14treewide: Add a function to change page permissionsIlias Apalodimas
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 Tested-by: Neil Armstrong <[email protected]> # on AML-S905X-CC Signed-off-by: Ilias Apalodimas <[email protected]>
2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <[email protected]> Signed-off-by: Tom Rini <[email protected]>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
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.

Remove <common.h> from the remainder of the files under arch/arm and when needed add missing include files directly. Signed-off-by: Tom Rini <[email protected]>

2020-05-18common: Drop net.h from common headerSimon Glass
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. Signed-off-by: Simon Glass <[email protected]>
2020-01-14armv7m: cache: add mmu_set_region_dcache_behaviour() stub for compatibilityGiulio Benetti
Since some driver requires this function add it as an empty stub when DCACHE is OFF. Signed-off-by: Giulio Benetti <[email protected]>
2019-12-03armv7m: cache: add invalidate_icache_all() stubGiulio Benetti
This commit: https://gitlab.denx.de/u-boot/u-boot/commit/d409c962169bd293e39386d0ddfa64d5222a3be4 causes build failure with ICACHE enabled. This is due to missing invalidate_icache_all() stub. Let's add empty invalidate_icache_all() in the case where ICACHE is not enabled. Signed-off-by: Giulio Benetti <[email protected]>
2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2019-05-18CONFIG_SPL_SYS_[DI]CACHE_OFF: addTrevor Woerner
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.

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 <[email protected]>
