   4 Subject: [PATCH 027/203] arm: mvebu: remove hardcoded static I/O mapping
   5
   6 Now that we have removed the need of the static I/O mapping for early
   7 initialization reasons, and fixed the registers area length that were
   8 broken, we can get rid of the static I/O mapping. Only the earlyprintk
   9 mapping needs to be set up, using the debug_ll_io_init() helper
  10 function.
