LS1043A PBL SD Card Boot

Section 27.5 of the QorIQ LS1043A Reference Manual, Rev. 3, 02/2017 States the following:


The PBL starts searching for the first good block. It begins to fetch the PBL image at the
starting address of that block.


Few questions on these two statements:


1. What represents a "good block"? (eg. a well formatted RCW?)

2. What is the definition of a PBL Image? (eg. Is it the RCW + PBI commands, just the RCW, etc. ?)

3. Does the PBL search for the RCW or must it exist at the starting address (for SD Card, sector 8)?
