Subject: [PATCH 09/11] RISC-V: Networking fix Hack
|
|
|
|
It looks like that kernel driver now supports reseting the
|
|
signal one additional time. As it had been already reset
|
|
twice in FSBL, PHY gets into incorrect state causing below error.
|
|
|
|
----------------------------------------------------------------------
|
|
macb 10090000.ethernet (unnamed net_device) (uninitialized): Could not attach to PHY
|
|
macb: probe of 10090000.ethernet failed with error -110
|
|
----------------------------------------------------------------------
|
|
|
|
This patch is just a temporary fix until we have a fix a FSBL.
|
|
It is just a **HACK** and **NOT TO BE MERGED** into mainline.
