[PATCH 0/5] 64-bit U-Boot configuration without SPL

Introduces a new configuration option X86_RUN_64BIT_NO_SPL to allow
building U-Boot as a 64-bit binary without using the SPL (Secondary
Program Loader). The motivation is to simplify the boot process for
specific x86-based platforms that do not require SPL, such as those
booting directly from a 64-bit coreboot firmware.

Jeremy Compostella (5):
  arch/x86: Add 64-bit U-Boot configuration without SPL
  arch/x86/cpu: Call x86_cpu_reinit_f for 64-bits
  arch/x86/lib: Fix CONFIG_X86_64 usage in zimage.c
  Fix EFI boot file name definition for 64-bit x86 architecture
  configs: Add coreboot64-no-spl_defconfig for 64-bit X86 without SPL
