Hi Derald,
Thanks for your patch, however, I don't like that we do not use the
CONFIG_SPL_GENERATE_ATMEL_PMECC_HEADER anymore... isn't this config
supposed to say whether we are going to generate the header or not ?
Checking if "not sd-boot" doesn't look like a good option... we may use
SPI boot or QSPI or some other type at some point and the issue will
still be there.
I would rather fix the original patch by Wenyou, namely move the #ifdef
below to not have the GENERATE_ATMEL_PMECC enabled for SDBOOT.
Does this sound good for you?
Thanks again,
Eugen
