Commit4687919684("serial: Remove DM_FLAG_PRE_RELOC flag in various drivers") essentially drops flag DM_FLAG_PRE_RELOC from serial_pl01x driver for Poplar platform, because the platform falls into the following strategy category made by the commit. Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Before the commit lands, Poplar platform works by statically declaring pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set in the driver. But since Poplar also supports device configuration from device tree, the commit practically drops the flag for Poplar, and hence breaks the platform from booting. This patch changes platform code and device tree to initiate pl011 serial device from device tree rather than static declaration, so that above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore the reported boot failure gets fixed.
