* src/soc: Get rid of most src/soc/Kconfig filesMartin Roth2022-06-241-1/+0
| | | | | | | | | | | | | | | Most of the src/soc/Kconfig files are only there for AMD and Intel to load the main SoC Kconfig files before any common files. That can be done in src/Kconfig instead. Moving the loads to the lower level allows the removal of all but the Intel soc/Kconfig file, which can be removed in a follow-on patch.

* treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner2022-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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. Then doing the same thing for BIOS_WARN with 's/printk\(\s*BIOS_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>

| | | | | | | | | | | | | Adds code taken and (barely) adapted from U-Boot (release 2020.04, commit 36fec02b1f90b92cf51ec531564f9284eae27ab4) for SDRAM initialization. This should in theory work for other configurations than the Beaglebone Black's DRAM configuration, but hasn't been tested.

* mb/ti/beaglebone: Load romstage/ramstage from SDSam Lewis2021-03-306-44/+26
| | | | | | | | | | | | | | | | | | | | | | Adds a "sd_media" boot_device to allow booting from the SD card. This assumes that the generated "MLO" file is placed at a 128KB offset from the start of the SD card, to allow for the MBR etc. to be at the start of the SD card. Placing the MLO file here allows the AM335x boot ROM to load and execute the bootblock stage as well, as 128KB is one of the offsets the boot ROM checks when looking for the next stage to execute. As part of this, a FMD for the Beaglebone has also been defined. It's sized at 32M somewhat arbitrarily, as SD cards could allow for much bigger payloads. TEST: Beaglebone boots from bootblock into romstage. Romstage to ramstage still doesn't work as it needs RAM initialization first.

* cbfs: Enable CBFS mcache on most chipsetsJulius Werner2020-12-021-0/+1
| | | | | | | | | | | | | This patch flips the default of CONFIG_NO_CBFS_MCACHE so the feature is enabled by default. Some older chipsets with insufficient SRAM/CAR space still have it explicitly disabled. All others get the new section added to their memlayout... 8K seems like a sane default to start with.

Enabling the MMU also gives some advantages in allowing the icache and dcache to be enabled, so is probably worth doing regardless.

* soc/ti/am335x: Fix MLO buildSam Lewis2020-09-094-10/+9
| | | | | | | | | | | | | | | | | | | | | | | Allows the AM335X to boot from the coreboot generated MLO by: - Fixing the load address in the MLO header to be the start of SRAM - Fixing the way that the bootblock size is calculated (which is embedded into the MLO so that the MLO knows how much to load into SRAM). The previous method relied on parsing cbfstool output - the output has changed format since this was originally written so this no longer works. Directly using the filesize of the built binary is probably a more stable way of doing this. As part of this, the start addresses of SRAM and DRAM were fixed to be consistent with the AM335x Technical Reference Manual (spruh73, rev Q).
