I see that CCSRBAR address is hardcoded in vmparam.h /* * Kernel CCSRBAR location. We make this the reset location. */ #define CCSRBAR_VA 0xfef00000 #define CCSRBAR_SIZE 0x00100000 Who change them: loader(8) or U-boot ? In Linux dts it's on another address: # grep CCSRBAR *.dts mpc8540ads.dts: reg = <e0000000 00100000>; // CCSRBAR 1M mpc8541cds.dts: reg = <e0000000 00100000>; // CCSRBAR 1M mpc8544ds.dts: reg = <e0000000 00100000>; // CCSRBAR 1M mpc8548cds.dts: reg = <e0000000 00100000>; // CCSRBAR 1M mpc8555cds.dts: reg = <e0000000 00100000>; // CCSRBAR 1M --
