It then stops and never print any more, I use mpc85xx_defconfig, I
select mpc85xxds in the menuconfig and deselect other options like
mpc8540ads etc.
Are you using the mpc8544ds device tree from 2.6.31, unchanged? Try
turning on CONFIG_PPC_EARLY_DEBUG.
No need to deselect the others, BTW.
Does mpc85xx_defconfig not work?
Yes mcp85xx_defconfig does not work, I can see mpc8540ads in the
menuconfig, but no mpc8544ds.
mpc8544ds is supported by CONFIG_MPC85xx_DS.
