To quote the author: I'm submitting a patch series that ports the gen_compile_commands.py script from the Linux kernel's sources to U-Boot. This script, originally located in scripts/clang-tools/gen_compile_commands.py, enables the generation of compile_commands.json file for improved code navigation and analysis. The series consists of the initial script import, the necessary modifications for U-Boot compatibility, and finally some documentation.

2023-10-11ARM: psci: move GIC address override to KconfigAndre Przywara
As the code to switch an ARM core from secure to the non-secure state needs to know the base address of the Generic Interrupt Controller (GIC), we read an Arm Cortex defined system register that is supposed to hold that base address. However there are SoCs out there that get this wrong, and this CBAR register either reads as 0 or points to the wrong address. To accommodate those systems, so far we use a macro defined in some platform specific header files, for affected boards. To simplify future extensions, replace that macro with a Kconfig variable that holds this override address, and define a default value for SoCs that need it.

2023-10-11misc: fs_loader: Fix alignment of fs_loader driverSean Anderson
DM_DRIVER_GET will redeclare the fs_loader driver without the correct alignment. This causes GCC to use the default section alignment of 32 bytes. This in turn creates a gap in the linker list due to the padding required to achieve the correct alignment, corrupting all further entries. Use DM_DRIVER_REF instead, which doesn't redeclare anything. Fixes: 0998a20cfc6 ("misc: fs_loader: Add function to get the chosen loader") Signed-off-by: Sean Anderson <seanga2@gmail.com>
2023-10-11mkimage: update man page and -h outputRasmus Villemoes
The man page correctly said that -B was ignored without -E, while the `mkimage -h` output suggested otherwise. Now that -B can actually be used by itself, update the man page. While at it, also amend the `mkimage -h` line to mention the connection with -E. The FDT header is a fixed 40 bytes, so its size cannot (and is not) modified, while its alignment is a property of the address in RAM one loads the FIT to, so not something mkimage can affect in any way. (In the file itself, the header is of course at offset 0, which has all possible alignments already.)

2023-10-11driver: rng: Add DM_RNG interface for ARMv8.5 RNDR registersAndre Przywara
The ARMv8.5 architecture extension defines architectural RNDR/RNDRRS system registers, that provide 64 bits worth of randomness on every read. Since it's an extension, and implementing it is optional, there is a field in the ID_AA64ISAR0_EL1 ID register to query the availability of those registers. Add a UCLASS_RNG driver that returns entropy via repeated reads from those system registers, if the extension is implemented. The driver always binds, but checks the availability in the probe() routine. This helps systems which suffer from low boot entropy, since U-Boot can provide entropy via the generic UEFI entropy gathering protocol to the OS, at an early stage.

Padding the header of an external FIT image is achieved by truncating the existing temporary FIT file to match the required alignment before appending image data. Reusing an existing file this way means that the padding will likely contain a portion of the original data not overwritten by the new header. Zero out any data past the end of the new header, and stop at either the end of the desired padding, or the end of the old FIT file, whichever comes first.

We're seeing sporadic errors like ENVC include/generated/env.txt HOSTCC scripts/basic/fixdep ENVP include/generated/env.in ENVT include/generated/environment.h HOSTCC tools/printinitialenv /bin/sh: 1: scripts/basic/fixdep: not found make[1]: *** [scripts/Makefile.host:95: tools/printinitialenv] Error 127 make[1]: *** Deleting file 'tools/printinitialenv' make: *** [Makefile:2446: u-boot-initial-env] Error 2 make: *** Waiting for unfinished jobs.... where sometimes the "fixdep: not found" is instead "fixdep: Permission denied" and the Error 127 becomes 126. This smells like a race condition, and indeed it is: Currently, u-boot-initial-env is a prerequisite of the envtools target, which also lists scripts_basic as a prerequisite: envtools: u-boot-initial-env scripts_basic $(version_h) $(timestamp_h) tools/version.h $(Q)$(MAKE) $(build)=tools/env However, the u-boot-initial-env rule involves building the printinitialenv helper, which in turn is built using an if_changed_dep rule. That means we must ensure scripts/basic/fixdep is built and ready before trying to build printinitialenv, i.e. the u-boot-initial-env rule itself must depend on the phony scripts_basic target.
