* fsl: serdes: ensure accessing the initialized maps of serdes protocolHou Zhiqiang2016-09-14-0/+9
| | | | | | | | | | | | Up to now, the function is_serdes_configed() doesn't check if the map of serdes protocol is initialized before accessing it. The function is_serdes_configed() will get wrong result when it was called before the serdes protocol maps initialized. As the first element of the map isn't used for any device, so use it as the flag to indicate if the map has been initialized.

* powerpc/85xx: Add is_serdes_configured() support for P2020 SERDESKumar Gala2011-01-14-0/+73
Add the ability to determine if a given IP block connected on SERDES is configured. This is useful for things like PCIe and SRIO since they are only ever connected on SERDES. Signed-off-by: Li Yang <leoli@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
