- desktop images have half the world in their initrd (plymouth?)
- `bdinfo` shows reserved regions, which are hit depending on the size of initrd
- when reserved region is hit, u-boot says `** Reading file would overwrite reserved memory **`
- done by AI after looking at `bdinfo` reserved regions
- hard lesson: all `0x` hex have to be double quoted, otherwise `Wrong image format for "source" command`
- add note about Meco having conjured up `load_addr` (it's `loadaddr`); doesn't hurt
- while at it, remove copypasta/duplicate bootlogo/consoleargs stanza
