Should I then also change RTD1395 to use only one cell, or does it
support more RAM than RTD1619?

By my calculation 0x98000000 is less than 2.4 GiB! So, does RAM continue
between r-bus and GIC, similar to how it does on RTD1195? Then we need
to exclude those RAM ranges from the SoC node (adjusting 0x68000000).

Andreas
