mtd: spelling, capitalization, uniformity
Therefor -> Therefore [Intern], [Internal] -> [INTERN] [REPLACABLE] -> [REPLACEABLE] syndrom, syndom -> syndrome ecc -> ECC buswith -> buswidth endianess -> endianness dont -> don't occures -> occurs independend -> independent wihin -> within erease -> erase blockes -> blocks ...
