General description of the PBI commands is provided in the QorIQ LS1043A Reference Manual, Chapter 27 Pre-Boot Loader (PBL).

Please note that default PBL base address offset is 0x100_0000 and this offset is concatenated with 24-bit SYS_ADDR of a PBI command.

Decoding example:

09570600 00000000

ACS=0

BYTE_CNT=000100 (4 bytes)

CNT=1

SYS_ADDR=570600

Complete CCSR address with offset: 0x1570600 (SCFG_SCRATCHRW0)
