[Buildroot] [PATCH] boot/edk2: drop dependency on tf-a for macchiatobin

[Vincent Stehlé]

When building a firmware for the MACCHIATObin with edk2 and
arm-trusted-firmware, the build fails with the following make error:

  make[1]: Circular output/build/edk2-edk2-stable202411/.stamp_configured <- arm-trusted-firmware dependency dropped.

In fact, only TF-A depends on EDK II (passed as BL33) for building and
not vice versa. [1]

Drop the false dependency on TF-A to fix the build.

Hi,

We have nothing in-tree to build edk2 for the MACCHIATObin; here is an
ad-hoc defconfig can be used for build-testing:

  BR2_aarch64=y
  BR2_TOOLCHAIN_EXTERNAL=y
  BR2_INIT_NONE=y
  BR2_SYSTEM_BIN_SH_NONE=y
  # BR2_PACKAGE_BUSYBOX is not set
  # BR2_PACKAGE_IFUPDOWN_SCRIPTS is not set
  # BR2_TARGET_ROOTFS_TAR is not set
  BR2_TARGET_ARM_TRUSTED_FIRMWARE=y
  BR2_TARGET_ARM_TRUSTED_FIRMWARE_PLATFORM="a80x0_mcbin"
  BR2_TARGET_ARM_TRUSTED_FIRMWARE_EDK2_AS_BL33=y
  BR2_TARGET_BINARIES_MARVELL=y
  BR2_TARGET_EDK2=y
  BR2_TARGET_EDK2_PLATFORM_SOLIDRUN_ARMADA80X0MCBIN=y
  BR2_TARGET_MV_DDR_MARVELL=y

Then to build, two options:

1. Use the in-flight TF-A build fix. [776370]
2. Build only `edk2'.

Best regards,
Vincent.
