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>

2021-09-13device/dram: Add addtional LPDDR4 speed gradesRob Barnes
Add additonal LPDDR4 speed grades. This is needed because the limited set has casued confusion when the reported speed did not match expectations. There does not seem to be a definitive list of LPDDR4 speed grades, so this list is derieved from JEDEC 209-4C and a survey of commonly used LPDDR4 speed grades.
