d83bb0be12 net: gemini: Depend on HAS_IOMEM
The zeroday builder notices that since Usermode Linux does not
have IO memory, the build fails for them when selecting everything
it can enable.

As the driver is clearly using memory-mapped registers to access
the network adapter, we add depends on HAS_IOMEM to solve this
problem.

4d5ae32f5e net: ethernet: Add a driver for Gemini gigabit ethernet
The Gemini ethernet has been around for years as an out-of-tree
patch used with the NAS boxen and routers built on StorLink
SL3512 and SL3516, later Storm Semiconductor, later Cortina
Systems. These ASICs are still being deployed and brand new
off-the-shelf systems using it can easily be acquired.

The full name of the IP block is "Net Engine and Gigabit
Ethernet MAC" commonly just called "GMAC".

The hardware block contains a common TCP Offload Enginer (TOE)
that can be used by both MACs. The current driver does not use
it.
