Subject: ar71xx: Use private version of ath79_setup_qca955x_eth_cfg for MR900
|
|
|
|
The MR900 must unset some bits in ETH_CFG which were set by u-boot to work
|
|
correctly under OpenWrt. But the global function
|
|
ath79_setup_qca955x_eth_cfg will not unset all of them to increase the
|
|
backward compatiblity with older mach-* files. A private (simplified)
|
|
version for MR900 can be used instead.
|
|
