That's... really huge.  Is there something else that can perhaps come
out to allow that to fit in?  Can you share the rest of the config?  I'm
not seeing anything close to that by default here.  And I bring this up
because...

Given the problem with compatibility with other systems, I think we need
to have xloader-a and xloader-b, or to make the names still be
compatible:
	"uuid_disk=${uuid_gpt_disk};" \
	"name=xloader-b,start=128K,size=128K,uuid=${uuid_gpt_xloader};" \
	"name=xloader,start=128K,size=128K,uuid=${uuid_gpt_xloader};" \
	"name=bootloader,size=512K,uuid=${uuid_gpt_bootloader};" \

So that the first xloader is written to what the ROM considers the 3rd
try location.  If dra7xx won't actually try from that (I can't easily
test right this moment) then we need another misc inbetween xloader @
128KiB in and u-boot @ 386KiB in so that the U-Boot location is
compatible with the non-Android option.
