Why uninstall Earlycon?

->membase + UART01X_DR); if (unlikely (pl011_workaround_busy)) { while (!) ( Readl (Port->membase + uart01x_fr) Uart011_fr_txfe)) Cpu_relax (); } else { while (Readl (Port->membase + uart01x_fr) Uart01x_fr_busy) Cpu_relax (); } } From the PL011_PUTC implementation can see that the actual is directly through the Writel to write registers. So from the realization of Earlycon can know, Earlycon is directly write registers, so Earlycon flag contains con_boot this flag. So when the real console use
