Power-On Self Test

When the ATCA-F125 is booted, U-boot executes a series of Power-On Self test (POST)
routines. These routines check the functionality of different controllers and other on-board
resources. The result is stored in memory and has the following format.

Information about the POST status can also be obtained by reading the SYS FW
PROGRESS IPMI sensor. Depending on the POST status, the sensor holds the following
values.
