On platforms where the bootblock is not included in CBFS anymore (because it is part of another firmware section (IFWI or a different CBFS), the CRTM measurement fails. This patch adds a new function to provide a way at SoC level to measure the bootblock. Following patches will add functionality to retrieve the bootblock from the SoC related location and measure it from there. In this way the really executed code will be measured.

Chause doesn't get to x86 bootblock without the SPL table binary in the PSP directory table, so I assume that Majolica won't get to x86 bootblock either, since the Cezanne SoC default is not to include any SPL table binary. This was caused by a combination of commit 6c5ec8e31ccbe3d9bbf201c956fc3b54703a9767 (amdfwtool: Add options to support mainboard specific SPL table) that caused a regression in amdfwtool and commit c5b912f788765560c1db08f3341826b9c548b865 (soc/amd/cezanne: Allow to specify SPL table path in Kconfig) that removed the default for the Cezanne SoC. Fix this by adding the default SPL table file back to the fw.cfg file which will get ignored by amdfwtool when a mainboard selects SPL_TABLE_FILE and specifies another SPL table binary.

2022-03-10soc/amd/{common/vboot,cezanne}: Copy S0i3 verstage logs into cbmemRaul E Rangel
Now that SMM can write to CBMEM we can simply replay the transfer buffer cbmem console to move it into the main cbmem console. replay_transfer_buffer_cbmemc() relies on the EARLY_RAM linker symbols. Since the SMM rmodule get linked with a different linker script than bootblock/romstage it doesn't have access to these symbols. In order to pass these symbols into SMM, we parse the bootblock.map file and generate an early_ram.ld script. This script is then used when linking SMM. I replay the buffer in `smm_soc_early_init` because this call happens before `console_init()`. `console_init()` prints the SMM header and we want to append the verstage contents before printing the header to avoid confusion.
