In LS1043A which is the default Eth interface for tftp programming and GPIO for Watchdog circuit

[Abhilash_PV]

In the LS1043A is there any default Ethernet interface (like Ethernet Controller1(EC1) or EC2) that should be used for tftp programming?

Can any GPIO of LS1043A be used for giving pulse to an external Watchdog circuit or any dedicated GPIO is available for this purpose?

Primary Ethernet interface is defined in the board's header file, for example "ls1043ardb.h":

https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot/tree/include/configs/ls1043ardb...

as

#define CONFIG_ETHPRIME			"FM1@DTSEC3"

GPIOs can be used according to the board's designer needs.
