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 <neil.armstrong@linaro.org> # on AML-S905X-CC Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
2025-03-14arm64: mmu_change_region_attr() add an option not to break PTEsIlias Apalodimas
The ARM ARM (Rev L.a) on section 8.17.1 describes the cases where break-before-make is required when changing live page tables. Since we can use a function to tweak block and page permissions, where BBM is not required split the existing mmu_change_region_attr() into two functions and create one that doesn't require BBM. Subsequent patches will use the new function to map the U-Boot binary with proper page permissions. While at it add function descriptions in their header files.

2025-03-14arm: Prepare linker scripts for memory permissionsIlias Apalodimas
Upcoming patches are switching the memory mappings to RW, RO, RX after the U-Boot binary and its data are relocated. Add annotations in the linker scripts to and mark text, data, rodata sections and align them to a page boundary. It's worth noting that .efi_runtime memory permissions are left untouched for now. There's two problems with EFI currently. The first problem is that we bundle data, rodata and text in a single .efi_runtime section which also must be close to .text for now. As a result we also dont change the permissions for anything contained in CPUDIR/start.o. In order to fix that we have to decoule .text_rest, .text and .efi_runtime and have the runtime services on their own section with proper memory permission annotations (efi_rodata etc). The efi runtime regions (.efi_runtime_rel) can be relocated by the OS when the latter is calling SetVirtualAddressMap. Which means we have to configure those pages as RX for U-Boot but convert them to RWX just before ExitBootServices. It also needs extra code in efi_tuntime relocation code since R_AARCH64_NONE are emitted as well if we page align the section. Due to the above ignore EFI for now and fix it later once we have the rest in place.

2025-03-13Kconfig: Introduce CONFIG_WERRORPaul Barker
Add a new config option under "General setup" to enable the -Werror flag when building U-Boot. This is useful during development to help catch mistakes. This is based on a similar config option added to the Linux kernel by Linus in 2021 - see Linux commit 3fe617ccafd6 ("Enable '-Werror' by default for all kernel builds"). The modification of KBUILD_CFLAGS is done in Makefile.extrawarn, matching where it was moved in the kernel by Linux commit e88ca24319e4 ("kbuild: consolidate warning flags in scripts/Makefile.extrawarn").

Legacy PCI devices, like qemu's Bochs VGA device, are allowed to have prefetchable 32-bit BARs, while PCIe devices are not allowed to have 32-bit prefetchable BARs. Typically prefetchable BARs are 64-bit and typically the prefetch MMIO window is also 64-bit and placed above 4GiB, as it's the case on qemu sbsa-ref. Currently the U-Boot code assumes that prefetchable BARs are 64-bit BARs and always tries to assign them into the prefetch MMIO window. When a 32-bit BAR is marked as prefetch, but the prefetch area is not within the first 4GiB of the address space, then downgrade the BAR and place it in the non-prefetch MMIO window. For prefetch BARs there's no downside on being placed in non prefetch MMIO areas, besides the possible slower performance when a driver tries to map it Write-Combine. TEST: Fixes pci_auto on QEMU sbsa-ref fails to autoconfigure BAR0. Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com>
