[PATCH rza_u-boot-2017.05 2/2] rza2mevb: Use second Ethernet port if first one is not available

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When SW6-4 is switched off, the first Ethernet port is not available,
and thus doesn't work.  Hence fall back to using the second port
instead.

This allows to use TFTP when SDRAM is enabled (RZA2M_ENABLE_SDRAM is
defined), and the serial console is moved to SCIF2.
