I tried Secure boot before[1] with SPL and U-Boot proper and work well.

I'm observing authentication issue while loading U-Boot proper, U-Boot
proper now have features like SPL DM and SPL FIT etc

U-Boot SPL 2018.03-rc1-00182-gb81f7c9 (Feb 08 2018 - 17:19:03 +0530)
Trying to boot from MMC1
Expected Linux image is not found. Trying to start U-boot

Authenticate image from DDR location 0x17800000...
bad magic magic=0xb8 length=0x841b version=0x17
bad length magic=0xb8 length=0x841b version=0x17
bad version magic=0xb8 length=0x841b version=0x17
spl: ERROR:  image authentication unsuccessful
### ERROR ### Please RESET the board ###

Please let me know where I missed, I'm authenticating SPL and
u-boot-dtb.img now.
