ath79: move small-flash Engenius boards to tiny
This moves some of the Engenius boards from generic to tiny:
- EAP350 v1
- ECB350 v1
- ENH202 v1
For these, factory.bin builds are already failing on master
branch because of the unique situation for these boards:
- 8 MB flash
- an extra "failsafe" image for recovery
- TFTP does not work (barely possible with 600 MTU)
- bootloader loads image from a longer flash offset
- 1 eraseblock each needed for OKLI kernel loader and fake rootfs
- using mtd-concat to make use of remaining space...
The manual alternative would be removing the failsafe partition.
However this comes with the risk of extremely difficult recovery
if a flash ever fails because TFTP on the bootloader is bugged.
