Pali Rohár 0d06b058a5 marvell: uart: a3720: Increase TX FIFO EMPTY timeout from 2ms to 3ms ... TX FIFO has space for 32 characters. With default UART baudrate 115200 it takes more than 2ms to transmit all 32 characters, so wait at least 3ms before flushing TX FIFO. If WTMI firmware transmitted something via UART before TF-A was booted, some characters may still wait in TX FIFO when TF-A is initializing UART driver. So wait at least 3ms to ensure that HW has enough time to transmit all characters waiting in TX FIFO. This fixes an issue where sometimes characters transmitted on UART by our custom WTMI image are lost.
