Series [1/2] arm-bsp/juno: move to compressed initramfs image | expand

Commit Message

Jon Mason Jan. 18, 2023, 3:54 p.m. UTC 
Change u-boot and machine config to default to booting a compressed
initramfs.  This allows for easier testing.  A compressed image is
needed as the image is too big for the storage, and the error notifying
of such is vague.
