Hello!
I am using Yocto and meta-xilinx to build the Linux kernel 4.9 for
a Zynq XC7Z030. Now, in my organization some people said that:
"Xilinx currently runs a custom Linux distribution which ... has patches
to the kernel by Xilink which are not accepted yet in the upstream Linux
kernel."
So, my question is:
What are the differences of the Xilinx Linux kernel w.r.t. to the Linux kernel
(from kernel.org)?
The main difference is the support for dual-parallel QSPI flash memory. The
driver for that is in a state (and has been for years) that apparently cannot
be upstreamed.
So if your board doesn't have dual flash, I'd recommend using mainline Linux
instead.
Kind regards,
