Hello!
I saw that there is support for the Netgear R6250 in openwrt. So I thought
maybe the R7000 is not so far from being support. It's not ;-)
After I modified the R6250 config in openwrt to allow the initramfs image to be flashed. First problem I then saw is that the image loads fine, but on serial I get only rubbish. But the luck was on my
side, the device responded to ping and allowed me a login.
This is the CFE boot log:

The problems I have is that I do not know how to get the flash working. It
seems it is available via bcma, but not initialized.
I took a look at the r6250 dts file which is used here, but there is no
reference to the flash? Can someone give me a hint?
