I'm using LS1028A RDB board and if I want to have AVB functionality such as gPTP, FQTSS etc on the switch, how to enable those on all switch ports?

You can find the information on enabling/exercising all TSN/AVB
features currently supported in LS028A BSP in Layerscape LS1028A BSP
User Guide (LS1028ABSPUG), Section 4.2.13. The document can be found
here:

In document its mentioned for enabling ptp timestamping on switches we have to do 

devmem 0x1fc0900a0 w 0x00000004

section 4.2.13.4.2 . But this is failing for me saying,

-bash: devmem: command not found

although I'm using BSPv0.3.

Also in "Section 4.2.3 IEEE 1588", under notes, there is a mention about ptp4l on felix switch. Inorder to run ptp on all switch ports do we have to run ptp4l seperately on each switch ports?

You cannot run ptp4l directly on a switch port because it belongs
to the switch, not to the host. ptp4l can only run on a port
that directly connects to the host.

As of devmem, of you are working with Ubuntu root filesystem, you
can use apt package manager to get Ubuntu devmem2 package. See
LS1028A BSP, Section 3.2 for details.
