PS11, Line 129: memory_base = memory_base + CONFIG_SOC_INTEL_GFX_MEMBASE_OFFSET;
> memory_base += CONFIG_SOC_INTEL_GFX_MEMBASE_OFFSET; […]

I think the purpose of if clause is checking if memory bar is zero.

If we move this line above 'if clause', then we cannot catch "memory bar = 0" when CONFIG_SOC_INTEL_GFX_MEMBASE_OFFSET is not zero.
