[U-Boot] POST - Hardware Diagnose Commands methodologies

Hi,
I would like to know if there's any methodology or requirement documentation available for the POST Hardware Diagnose Commands from U-Boot, for microprocessor MPC8378?
Thanks,

POST code is inherently very closely hardware specific. If you read doc/README.POST you will see that the original design of the code was done for a MPC823E based system (LWMON, to be specific), and later it got extended to other boards and processors as needed.
There are generic (per architecture) tests, CPU model specific tests, SoC specific tests, standard peripheral tests, and board specific tests.
The requirement documentation for the tests comes from your own project - we cannot know what you need. You can then either match your requirements to existing code and reuse it unchanged, or youmay have to extend / mdify it, or you may have to add completely new pieces.
This depends on _your_ requirements.
Best regards,
Wolfgang Denk
