Probably not -- 2.6.23 is very old, and I think newer dtcs only= support the
newer dts syntax.

It should.  What p= roblems do you see?

It then stops and never print any more,  I use mpc85xx_defconfig,= I select mpc85xxds in the menuconfig and deselect other options like mpc85= 40ads etc.

Does mpc85xx_defconfig not work?
Yes mcp85xx_defconfig does not work, I can see mpc8540ads in the menuc= onfig, but no mpc8544ds. And when I down load the generated uImage, It does= not work.
