Should the serial4 and serial5 aliases keep pointing at lpuart devices so you can still drive all physical connectors?

The only existing reference I can find to the serial aliases is if the OF_STDOUT_VIA_ALIAS is enabled in u-boot to specify the console. The standard ls1043aqds_defconfig in u-boot specifies DUARTs for the console, which is why I'm proposing making the 4 DUARTs the default serial aliases in the device tree. There is a separate defconfig in u-boot to enable/use LPUARTs instead of the normal DUARTs. For that scenario, my take is that firmware should update the DT aliases to reflect the actual use of the serial ports. But, the default should be the DUARTs which is the normal case for this board, which is why this patch is changing them. Thanks, Stuart ^ permalink raw reply [flat|nested] 8+ messages in thread

Yes, that's the case with u-boot's defconfig. I'm still trying to find out whether that mutual exlusivity was a firmware decision or a hardware limitation.
