Issue #451 has been reported by Felix Singer.
---------------------------------------- Bug #451: Fix POST code handling https://ticket.coreboot.org/issues/451
* Author: Felix Singer * Status: New * Priority: Normal * Target version: none * Start date: 2023-01-29 ---------------------------------------- coreboot supports writing POST codes to I/O port 80. There are various Kconfigs that deal with POST codes, which don’t have effect on most platforms. The code to send POST codes is scattered in C and Assembly, some use functions, some use macros and others simply use the `outb` instruction. The POST codes are duplicated between stages and aren’t documented properly.
## Tasks
* Guard Kconfigs with a depends on to only show on supported platforms * Remove duplicated Kconfigs * Replace `outb(0x80, ...)` with calls to `post_code(...)` * Update Documentation/POSTCODES * Use defines from console/post_codes.h where possible * Drop duplicated POST codes * Make use of all possible 255 values
## Requirements
* Knowledge in the coreboot build system and the concept of stages * Other knowledge: Little experience with C and x86 Assembly * Hardware requirements: Nothing special
## Mentors

Martin started another discussion regarding POST codes with the "coreboot postcode cleanup proposal" thread.
