Hi Bryan,

This patch adds IVT_PAD_SIZE at 0xC00. The IVT header is padded to this size. Defining the size explicitly makes it possible to use the define to locate the start/end of an IVT header without using magic numbers in code.
As far as I know the 0xC00 pad size is only mandatory in U-Boot/SPL images, for instance in some U-Boot images the first 0xC00 should include IVT + Boot data + DCD table + padding to 0xC00. Are you using the IVT_PAD_SIZE in your current code? Or this macro will be used in a next series?
Thanks, Breno Lima
All of my images - kernel, u-boot, optee, boot.scr are signed in the same first-stage format with this padding present - for simplicity.
Maybe this better named "BOOTROM_IVT_PAD_SIZE" since only the bootrom requires it.
