2022-08-17	soc/amd/cezanne,picasso,sabrina/smihandler: add comment about SMN access	Felix Held
	The SMI sleep entry handler will access the SMN space via the index/data register at PCI config space offsets 0xb8 and 0xbc of the device at bus 0, device 0, function 0. This register pair is also used by other software components running on the x86 cores after boot, so it should be saved and restored at the beginning/end of the SMI handler if it accesses SMN. The sleep entry SMI handler is a special case, since the OS is already done at the moment we enter the sleep SMI handler which is the last code that gets run on the x86 cores before entering S3/4/5.

2022-03-10	soc/amd/{common/vboot,cezanne}: Copy S0i3 verstage logs into cbmem	Raul 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. BUG=b:221231786 TEST=Perform S0i3 cycles and verify PSP verstage logs now show up when doing `cbmem -c`.

2022-02-07	treewide: Remove "ERROR: "/"WARN: " prefixes from log messages	Julius Werner
	Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\sBIOS_ERR,\s"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result. Then doing the same thing for BIOS_WARN with 's/printk\(\sBIOS_WARNING,\s"WARN(ING)?: /printk\(BIOS_WARNING, "/gi' Signed-off-by: Julius Werner <jwerner@chromium.org> Change-Id: I3d0573acb23d2df53db6813cb1a5fc31b5357db8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/61309 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr> Reviewed-by: Lance Zhao Reviewed-by: Jason Glenesk <jason.glenesk@gmail.com>
