For the most part, this doesn't change any post codes, simply making the existing post-codes into macros. picasso/romstage.c did get a couple of post codes removed to match the other files. The POST_ROMSTAGE and POST_BOOTBLOCK codes are intended to become global at some point, while the POST_AGESA and POST_PSP codes would stay AMD specific.

2022-08-25soc/amd: rework SPI flash MMIO region handlingFelix Held
Only 16 MByte of the SPI flash can be mapped right below the 4 GB boundary. In case of a larger SPI flash size, still only the 16 MByte region starting at 0xff000000 can be configured as WRPROT and be reserved for the MMIO mapped SPI flash region. The next 16 MByte MMIO region starting at address 0xfe000000 contain for example the LAPIC MMIO region, the ACPIMMIO region and the UART/I2C controller MMIO regions which shouldn't be configured as WRPROT. Reserving this region for the MMIO mapped SPI flash would also result in an overlap with the MMIO resources mentioned above. In the case of a smaller SPI flash, reserving the full 16 MByte flash MMIO region makes sure that the resource allocator won't try to put anything else in the lower parts of the 16 MByte SPI mapping region. To avoid the issues described above, always reserve/cache the maximum amount of 16 MBytes of flash that can be mapped below 4 GB. TEST=On boards with 16 MByte SPI flash chips, the resulting image of a timeless build doesn't change with this patch. Verified this on Chausie (Mendocino), Majolica (Cezanne), Cereme (Picasso) and Google/Careena (Stoneyridge). On Mandolin (Picasso) with an 8 MByte flash, the resulting image of a timeless build is different, but neither the coreboot console output nor the Linux dmesg output shows any errors that might be related to this change.

This gets called by the common lpc_early_init which also calls lpc_disable_decodes and lpc_set_spibase.

The AMD SoCs had a check to make sure that HPET_ADDRESS_OVERRIDE isn't set so that the HPET_ADDRESS Kconfig option will have the right default value. Instead check if the HPET_ADDRESS Kconfig value matches the HPET_BASE_ADDRESS define in the SoC code which is the case if HPET_ADDRESS_OVERRIDE isn't selected.

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.

2021-12-09soc/amd/stoneyridge: use common fch_spi_early_initFelix Held
All SPI interface setup related functionality that Stoneyridge implemented in its southbridge code is already present in the common AMD SoC code, so use that code instead. The common fch_spi_early_init function requires the SPI controller's base address to be set, so call lpc_set_spibase(SPI_BASE_ADDRESS) right before it. fch_spi_early_init then calls lpc_enable_spi_rom and lpc_enable_spi_prefetch which can be removed from the board code now. Next it calls fch_spi_configure_4dw_burst which does the same as the now removed sb_disable_4dw_burst function when SOC_AMD_COMMON_BLOCK_SPI_4DW_BURST is set to n which is the default. This option can also only be set to y for SoCs that aren't Stoneyridge. Finally fch_spi_early_init calls fch_spi_config_modes which configures the SPI mode and speed settings according to the Kconfig settings and the settings in the amdfw part. On Kahlee this was done by calls to sb_read_mode and sb_set_spi100 before. The previous patch added the remaining Kconfig settings, so the resulting register values don't change in the non-EM100 case. In the EM100 case the TPM speed is changed from 64 to 16 MHz. TEST=Both the non-EM100 mode with a real SPI flash and the EM100 mode with a first-generation EM100 results in Google/Barla reaching the payload and the show_spi_speeds_and_modes call in bootblock prints the expected settings: relevant bootblock console output in non-EM100 case: SPI normal read speed: 33.33 MHz SPI fast read speed: 66.66 Mhz SPI alt read speed: 66.66 Mhz SPI TPM read speed: 66.66 Mhz SPI100: Enabled SPI Read Mode: Dual IO (1-2-2) relevant bootblock console output in EM100 case: SPI normal read speed: 16.66 MHz SPI fast read speed: 16.66 MHz SPI alt read speed: 16.66 MHz SPI TPM read speed: 16.66 MHz SPI100: Enabled SPI Read Mode: Normal Read (up to 33M) Signed-off-by: Felix Held <felix-coreboot@felixheld.de> Change-Id: I8f37a3b040808d6a5a8e07d39b6d4a1e1981355c Reviewed-on: https://review.coreboot.org/c/coreboot/+/59968 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Marshall Dawson <marshalldawson3rd@gmail.com>
