[PATCH 00/11] Reduce usage of timestamp macros

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):

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
