No problem have a look at it when you find some time for it. There are

Now I think this will be the fastest solution. Henry Ptasinski from
Broadcom wanted to make it possible for us to use the Braodcom driver
directly as a base, but talking to all the lawyers and managers at
Braodcom to make this possible takes a lot of time and is not promising.
After this and flash support is in the kernel I will work on the

spec and implement it.
I published my git repo with the modifications integrated into OpenWrt:
