U-Boot Calculation for Arch Linux ARM on Odroid

DOING THE MATH:
((OFFSET X 512 BYTES) + (SIZE OF tzsw.bin IN BYTES)) / 512
((2111 x 512) + 262144) = 1342976 / 512 =  2623 SECTORS

I had the file size for u-boot.bin originally, but I am still getting over 2048 after correcting this.
Am I doing something wrong here?  I have looked at this a few times.  I'll try this calculation again in the morning.
