Some malloc memory is needed at startup for DM model. Lets reorganise the use of the CPM dpram.
The MPC866/885 dpram, we have 8kbytes dual port RAM, which is usable as: IMMR + 0x2000..0x2800: BD/Data/Microcode IMMR + 0x2800..0x2e00: BD/Data IMMR + 0x2e00..0x3800: BD/Data/Microcode IMMR + 0x3800..0x3a00: BD/Data IMMR + 0x3a00..0x3c00: BD/Data/Microcode IMMR + 0x3c00..0x4000: Parameters for the Peripheral Controllers
Lets reallocate all BDs in the 3800..3a00 area and give the full 2800..2e00 for dynamic RAM allocation including global data
That way, the microcode areas remain available if needed one day.
