[U-Boot-Users] [RFC] CFI Driver Little-Endian write Issue

[Li Yang-r58472]

Please ignore my last question.  Lately, I find out in your .c file that
there are still some places using __LITTLE_ENDIAN.

However, I still have a question that in which condition
CFG_FLASH_CFI_SWAP is required to set?

Best Regards,
Leo
