The DM_FLAG_PRE_RELOC shall be enabled in SBSA PL011 uart driver as this driver is used in NXP based SoCs
It is necessary to have Serial console running before relocation
The !CONFIG_IS_ENABLED(OF_CONTROL) [*] check is set as "workaround" for DM problem : 4687919684e
This flag is set if board does not support device-tree and using platform data, In DM Model either of device tree or platform data can be used to fetch device configuration
It is possible to use SBSA UART with CONFIG_DM_SERIAL but witout corresponding device tree description (OF_CONTROL)
Other board/SoCs have this flag set unconditionally
