2023-10-04	soc/amd: rework SPL file override and SPL fusing handling	Felix Held
	The SPL_TABLE_FILE and SPL_RW_AB_TABLE_FILE Kconfig options provide a way to override the default SPL file configured in the SoC's fw.cfg file by passing the '--spl-table' parameter to amdfwtool which will then use the override instead of the SPL file from the fw.cfg file. When SPL*_TABLE_FILE is an empty string, the corresponding add_opt_prefix call in the makefile will result in no '--spl-table' parameter being passed to amdfwtool, so it'll use the default SPL file from fw.cfg. In order to not pass an SPL override by default, remove the default from the SPL_TABLE_FILE in the SoC's Kconfig. The SoC default pointed to the same SPL file as in fw.cfg file anyway. Now only when a mainboard sets this option to point to a file, that file will be used as an override. This override is used to include a special SPL file needed for the verstage on PSP case on the Chromebooks. Since SPL_TABLE_FILE is an empty string by default, neither the SPL_TABLE_FILE Kconfig option nor it being evaluated in the Makefile need to be guarded by HAVE_SPL_FILE, so remove the dependency in the Kconfig and the ifeq in the Makefile. Before this patch, the HAVE_SPL_FILE option controlled two things that shouldn't be controlled by the same Kconfig option: Only when HAVE_SPL_FILE was set to y, the SPL_TABLE_FILE override was taken into account, and it also controls if spl_fuse.c got added to the build which when added will send the SPL fusing command to the PSP. So the case of needing an SPL file override, but not updating the SPL fuses wasn't supported before. The SPL file in the amdfw part will be used by the PSP bootloader for the anti-rollback feature which makes sure that the SPL file version isn't lower than what is in the SPL fuses. For this the SPL file needs to be present in the PSP directory table. The SPL version check happens way before we're running code on the x86 cores. The SPL fusing PSP command that can be sent by coreboot will tell the PSP to update the SPL fuses so that the fused minimal SPL version will be updated to the current SPL version. Since the former HAVE_SPL_FILE option now only controls if the SPL fusing command will be sent to the PSP mailbox, rename it to PERFORM_SPL_FUSING to clarify what this will do and update the help text correctly describe what this does. TEST=With INCLUDE_CONFIG_FILE set to n, timeless builds for both Birman with Phoenix APU and Skyrim result in identical binaries.
