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
