Re: [dts] [PATCH 1/6] framework: crb :add some parameters and check_Mellanox_pci function to identify mellanox device

[Raslan Darawsheh <rasland@mellanox.com>]

Hi Xu, HuilongX ,

>From what I changed it seems that it's only executed over the linux OS. And there are an already "lspci" command executed inside the function. 
Can you explain more ?
Kindest regards
