[U-Boot] post_codes in u-boot?

[Haleigh Novak]

Hello All,


I am currently deciphering post_code ouput on a machine running Yocto with a bios of coreboot with a payload of SeaBIOS and another (i think) u-boot, in searching online for one of the post_code values I stumbled on a post (http://lists.denx.de/pipermail/u-boot/2016-January/241577.html) noting that u-boot has post codes of its own. I was wondering if there was a consolidation of most (if not all) of the post_codes used, like there sort of is in coreboot at /src/console/post_code.h; or if there is not would someone mind giving me a direction on what function(s) u-boot uses to post the u-boot post_codes; i.e. coreboot utilizes a function called post_code as well as asm code and some of the binaries have their own post codes  - is there anything like that in u-boot?


Thank you for your time.

See arch/x86/include/asm/post.h. There is a function post_code() to do
post codes.
