The usual way to program SPL into NAND flash is to use the SAM-BA Atmel tool.
This however is often not usable when doing field updates. To be able to
look like. In order to do so we have a new image type added to mkimage to
generate this PMECC header and integrated this into the build process of SPL.
-To enable the generation of atmel PMECC header for SPL one need to define
+To enable the generation of atmel PMECC header for SPL one needs to define
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER. The required parameters are taken from
board configuration and compiled into the host tools atmel_pmecc_params. This
tool will be called in build process to parametrize mkimage for atmelimage
