The __earlycon_table lives in a special "__earlycon_table" section. The contents of this table are added using some macros that deposit individual struct earlycon_id entries into this section. The linker then defines a symbol __earlycon_table that is supposed to contain the addresss of the first of these entries. The code in earlycon.c and fdt.c then tries to access the memory pointed to by __earlycon_table as an array of struct earlycon_id entries.
Unfortunately, the compiler doesn't always place the entries such that they are an array. Let's fix that. Patch 1 of the series is a fix that should hopefully fix a kbuild error that seems to be triggered by Patch 2.
