320 On some boards, which use 'falcon' mode, it is necessary to check
321 and increment the number of boot attempts. Such boards do not
322 use proper U-Boot for normal boot flow and hence needs those
323 adjustments to be done in the SPL.

412 SPL starts off execution in SRAM and thus typically has only a small
