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.
