All the kernel work is in the BK repository linux-shmedia
(linux-shmedia.bkbits.net).

Pretty much

The short answer is no, only 32 bit addresses spaces are supported.

We need to distinguish between the SHmedia architecture and the current
SH5 implementation of that architecture. The SHmedia architecture is fully
64 bit, but the SH5 implementation doesn't implement full 64 bits in all
cases. In particular addresses are only 32 bit. So the current kernel
implementation can be more efficient by only managing 32 bit addressing.

Hope this helps
