Revert "arm64: Use FEAT_HAFDBS to track dirty pages when available"

2023-11-17T16:58:26Z

This reverts commit 6cdf6b7a340db4ddd008516181de7e08e3f8c213. This is part of a series trying to make use of the arm64 hardware features for tracking dirty pages. Unfortunately this series causes problems for the AC5/AC5X SoCs. Having exhausted other options the consensus seems to be reverting this series is the best course of action.

arm64: Use level-2 for largest block mappings when FEAT_HAFDBS is present

2023-04-25T19:31:27Z

In order to make invalidation by VA more efficient, set the largest block mapping to 2MB, mapping it onto level-2. This has no material impact on u-boot's runtime performance, and allows a huge speedup when cleaning the cache. Signed-off-by: Marc Zyngier [ Paul: pick from the Android tree.

arm64: Use FEAT_HAFDBS to track dirty pages when available

2023-04-25T19:31:27Z

Some recent arm64 cores have a facility that allows the page table walker to track the dirty state of a page. This makes it really efficient to perform CMOs by VA as we only need to look at dirty pages. Signed-off-by: Marc Zyngier [ Paul: pick from the Android tree.

imx: imx8ulp: Adjust handshake to sync TRDC and XRDC completion

2023-03-29T18:15:42Z

To fit the DBD_EN fused part, we re-design the TRDC and XRDC assignment. M33 will be the TRDC owner and needs to configure TRDC. A35 is the XRDC owner, ATF will configure XRDC. The handshake between U-boot and M33 image is used to sync TRDC and XRDC configuration completion. Once the handshake is done, A35 and M33 can access the allowed resources in others domain. The handshake is needed when M33 is booted or DBD_EN fused, because both cases will enable the TRDC. If handshake is timeout, the boot will hang. We use SIM GPR0 to pass the info from SPL to u-boot, because before the handshake, u-boot can't access SEC SIM and FSB. Signed-off-by: Ye Li Reviewed-by: Jacky Bai

global: Move remaining CONFIG_SYS_* to CFG_SYS_*

2022-12-05T21:06:08Z

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini Reviewed-by: Simon Glass

Makefile: Allow LTO to be disabled for a build

2022-09-02T20:20:11Z

LTO (Link-Time Optimisation) is an very useful feature which can significantly reduce the size of U-Boot binaries. So far it has been made available for selected ARM boards and sandbox. However, incremental builds are much slower when LTO is used. For example, an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7 seconds with LTO enabled. Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be disabled during development if needed, for faster builds. Add some documentation about LTO while we are here.
