It's very interesting. Please find my recent post with patch for
NAS4220. It has CS3516 SoC with the same(?) FA526 core.
Few comments inline below.

where is your physical DRAM base?
Where does your system boot from? Does it execute code directly from
Flash memory? I am asking, because CS351x does that very strange: some
hardware(?) locig copies 2K from Flash base to internal SDRAM, mapped to
0x0 address. After that it starts execute code from SDRAM.
This caused me to change cpu/arm920t/start.S and make linker script.
You didn't such modifications, so I understand, this is Gemini specific,
not Faraday FA526 core?
Should be possibility to make something common for your SoC and Gemini
processors?
