If you device lacks flash for environment then create "BIOS boot 
partition" and use it for storing both bootloader and env?

Something like 552d426f-6f74-2070-6c75-7320456e762020 (plus some endian 
swaps) would be better UUID for U-Boot Env partition as it goes to 
"U-Boot plus Env" after ASCII convertion ("BIOS Boot partition" UUID is 
"Hah!IdontNeedEFI" so why not continue tradition).
