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. 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>
2022-02-03soc/amd/*/i2c: factor out common I2C pad configurationFelix Held
The I2C pad control registers of Picasso and Cezanne are identical and the one of Sabrina is a superset of it, so factor out the functionality. To avoid having devicetree settings that contain raw register bits, the i2c_pad_control struct is introduced and used. The old Picasso code for this had the RX level hard-coded for 3.3V I2C interfaces, so keep it this way in this patch but add a TODO for future improvements.

I2C driver is replicated in each generation of AMD SoCs. Introduce a common I2C driver that can be used across all the AMD SoCs. To begin with, peripheral reset functionality is moved into this common driver. SoC specific I2C driver passes the SCL pin configuration in order for the common driver to reset the peripherals. More functionality can be moved here in subsequent changes. Also sb_reset_i2c_slaves() is renamed as sb_reset_i2c_peripherals() as an effort towards using inclusive language.

We've moved much of the duplicated stoney code into the soc/amd/common directory and will continue that work as it becomes obvious that we have unchanged code between the SOCs. Makefile.inc has been renamed as makefile.inc so that it won't build in jenkins until the directory is updated.
