FS#12117 - Use more IRAM for atrac3
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.
