Including timestamp.h (either directly or transitionally) cause build system to recompile binaries at every 'make' run. This has disadvantage in U-Boot development as for every small change 'make' recompiles lot of other irrelevant files which were not touched / changed.
This patch series eliminate transitional / indirect usage of timestamp.h by removing unneeded inclusion of header files, moving timestamp values from macros to global variables, etc...
After these patches, U-Boot tools are not recompiled by every 'make' run, which decrease time for incremental U-Boot recompilation.
Please test these patches, specially m68k and powerpc parts as I do not have any of these boards.
Patch series depend on this patch (now marked as accepted): http://patchwork.ozlabs.org/project/uboot/patch/20210710111001.32325-1-pali@...
Pali Rohár (11): Remove #include <timestamp.h> from files which do not need it Remove #include <version.h> from files which do not need it efi_loader: Use directly version_string variable version: Move version_string[] from version.h to version_string.h m68k: mcf: Remove overloading version_string version: Put version_string[] variable into section .text_version_string powerpc: mpc: Put U-Boot version string at correct place by linker script version: Do not make version_string[] variable as a weak x86: quark: MRC: Remove U_BOOT_DATE and U_BOOT_TIME from debug log version: Remove global macro U_BOOT_VERSION_STRING from version.h Remove including timestamp.h in version.h
