SPL now loads ATF (BL31), U-Boot proper and DTB from FIT image. The new boot flow with ATF support is as follow:
SPL -> ATF (BL31) -> U-Boot proper -> OS (Linux)

Why did the text base change ?
This defconfig support ATF. ATF will occupy from this address range (0x1000) U-Boot now starts at 0x200000.
Then please document it in the commit message.
Or even better, could we have 2 defconfigs, one for ATF, one for non-ATF? That way, we get build coverage that this still works.

Is legacy image support really needed ?
Let me check. Will get rid of this if it's not needed. Thanks.
Thanks
