If defined, hardware flash sectors protection is used
instead of U-Boot software protection.
-- CONFIG_SYS_DIRECT_FLASH_TFTP:
-
- Enable TFTP transfers directly to flash memory;
- without this option such a download has to be
- performed in two steps: (1) download to RAM, and (2)
- copy from RAM to flash.
-
- The two-step approach is usually more reliable, since
- you can check if the download worked before you erase
- the flash, but in some situations (when system RAM is
- too limited to allow for a temporary copy of the
- downloaded image) this option may be very useful.
-
- CONFIG_SYS_FLASH_CFI:
Define if the flash driver uses extra elements in the
common flash structure for storing flash geometry.
