I know this break socfpga, and that's why I cc you for help, could you
help the take a look if we can have a solution on socfpga to "make it
work with this patch"?

Comments from Philipp[0] show that its reasonable for this patch set,
I don't know how the boot0-hook works in socfpga and also sunxi and bcm,
could you help me to fix the hook content upon this patch?

Thanks,
