	3b08007 Browse files » board/MynaPlayer odyssey: modify boot spec entry. ... The bootloader specs file doesn't set earlycon anymore (this was unsupported), and rootwait is now set to have the kernel wait for the root device (required when booting without an initramfs).

	92c2fba Browse files » board/MynaPlayer odyssey: removed initramfs. ... This build no longer requires an initramfs. It has hence been removed entirely. The associated defconfig is deleted, as are the postbuild and postimage scripts and overlays. The patches have been relocated to the rootfs_patches directory. Also worth noting is that the machine-id setup is entirely gone from the build system. Xogium committed on 9 Aug 2020
