For Kirkwood boards, it is necessary to have early malloc in DRAM area when Driver Model for Serial is enabled. Please see Michael's patch here: https://lore.kernel.org/u-boot/20220817193809.1059688-20-michael@walle.cc/
This patch enables the early malloc in DRAM for all Kirkwood boards. Note that this will work for boards that have either non-DM serial and DM_SERIAL. Also, add the CONFIG_KIRKWOOD_COMMON option to enable DM_SERIAL as a common option for boards that have been tested.
