#     Documentation/powerpc: update fadump implementation details
#     
#     The patch titled ("powerpc: make fadump resilient with memory add/remove
#     events") has made significant changes to the implementation of fadump,
#     particularly on elfcorehdr creation and fadump crash info header
#     structure. Therefore, updating the fadump implementation documentation
#     to reflect those changes.
#     
#     Following updates are done to firmware assisted dump documentation:
#     
#     1. The elfcorehdr is no longer stored after fadump HDR in the reserved
#        dump area. Instead, the second kernel dynamically allocates memory
#        for the elfcorehdr within the address range from 0 to the boot memory
#        size. Therefore, update figures 1 and 2 of Memory Reservation during
#        the first and second kernels to reflect this change.
#     
#     2. A version field has been added to the fadump header to maintain
#        backward compatibility without changing the fadump header magic
#        number in the future. Therefore, remove the corresponding TODO from
#        the document.
