2023-10-09soc/amd/common/vboot: Fix PSP verstage timestamps after TSC adoptionKarthikeyan Ramasubramanian
Commit 26d54b70e282 ("soc/amd/common/cpu: use TSC_MONOTONIC_TIMER for SOC_AMD_COMMON_BLOCK_TSC") updated all the AMD SoCs with Zen-based CPU cores to use TSC_MONOTONIC_TIMER. The same change adjusted the PSP Verstage timestamps (in microseconds) to the x86 TSC rate. But it included only the base_time during the adjustment leaving the individual entry timestamp. This leads to incorrectly adjusted PSP Verstage timestamps. Fix the adjustment logic. BUG=None TEST=Build and boot to OS in Skyrim. Ensure that the PSP Verstage timestamps in cbmem -t output are adjusted correctly.

2023-08-26soc/amd: Move psp_transfer.h out of each SOC into commonMartin Roth
The psp_transfer.h file was the same under all SoCs, and is really tied to the file common/vboot/transfer.c, not the SOC. This patch makes an include directory under vboot to put the header into and sets it to be included for all SoCs using SOC_AMD_COMMON. This makes the header file available to all platforms, so that new chips that don't use the psp_verstage don't have to make a psp_transfer.h file just to satisfy the compiler.

2023-03-31soc/amd/common/cpu: use TSC_MONOTONIC_TIMER for SOC_AMD_COMMON_BLOCK_TSCFelix Held
All AMD SoCs with Zen-based CPU cores are already using timestamps based on the TSC counter, so use the existing common infrastructure instead of reimplementing it in a similar way. The behavior of the code changes slightly, but results in identical timestamps. The timestamp_get implementation in soc/amd/common/block/cpu divided the result of rdtscll() in timestamp_get by the result of tsc_freq_mhz() and didn't override the weak timestamp_tick_freq_mhz implementation that returns 1. The non AMD specific code returns the result of rdtscll() in timestamp_get, but returns tsc_freq_mhz() instead of 1 in timestamp_tick_freq_mhz, so we still get the correct timestamps. TEST=The raw timestamps printed on the serial console are now multiplied by the expected factor of the TSC frequency in MHz. TEST=Normalized timestamps printed on the serial console by the x86 code don't change significantly on Mandolin when comparing before and after this patch. A slight variation in the timestamps is expected. An example would be: Before: CPU_CLUSTER: 0 init finished in 630 msecs After: CPU_CLUSTER: 0 init finished in 629 msecs TEST=The calculations of the time spent in verstage on PSP before entering the bootblock on Guybrush result in similar times when multiplying the value before the patch with the TSC frequency in the case with the patch applied. The raw values printed on the serial console by the verstage on PSP use the 1us time base, but the timestamp logs that end up in CBMEM will be fixed up to use the same time base as the x86 part of coreboot.

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. BUG=b:221231786 TEST=Perform S0i3 cycles and verify PSP verstage logs now show up when doing `cbmem -c`.

2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius 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\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.

2022-01-23soc/amd/{common,cezanne,picasso}: Add PRE_X86_CBMEM_CONSOLE_SIZERaul E Rangel
This change splits the size of the console transfer region and size of the bootblock/romstage Pre-RAM console region. This allows having a larger Pre-RAM console while not impacting the size of the PSP verstage console. Instead of directly using the PRE_X86_CBMEM_CONSOLE_SIZE symbol in `setup_cbmem_console`, I chose to use the offsets provided in the transfer buffer. It would be nice to eventually do this for all the fields in the transfer buffer.
