[PATCH 3/5] board/Synology: Unify legacy kernel support
Phil Sutter

Wed Mar 3 01:55:24 CET 2021
Move the relevant bits from ds109.{c,h} into common/ and adjust the code
to fit both DS109 and DS414. Moreover:
* Introduce syno_board_id() which translates CONFIG_MACH_TYPE into the
expected board ID tag value.
* Properly initialize isusbhost, mac and mtu fields from env variables.
* Set the right bootargs/bootcmd to correctly boot legacy kernel out of
the (DS414) box. Getting the ramdisk location right is a bit tedious.
