The attached patch moves several additional data arrays to IRAM for MCF5250, PP5022 and PP5024. It also enables the usage of the configuration for large IRAM on S5L870x (how could I oversee this...).
I will measure the impact on performance on PP5022 and S5L870x tomorrow. Maybe someone else can measure the effect on MCF5250.
