Back in the AR71XX days, the lzma-loader code could be customized based on the $BOARD variable. These would be passed as a compile-time -DCONFIG_BOARD_$DEVICE_MODEL flag to the compiler. Hence, the lzma-loader would be able to include device-specific fixups. Note: There's still a fixup for the TpLink TL-WR1043ND V1 found in the lzma-loader's board.c code. But since the days of AR71XX I couldn't find a forum post or bug reported. So, I left it as is to not break anything by enabling it. => If you have a TL-WR1043ND V1 and you have problem with the ethernet: let me know. Because otherwise, the fixup might simply no longer needed with ath79 and it can be removed. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
