[U-Boot] build fail due to dependence error

Hi Guys,

I met below error from time to time when build U-Boot project.

fixdep: error opening config file: arch/arm/include/asm/arch/hardware.h: No such file or directory

The folder 'arch/arm/include/asm/arch' is a link for 'arch/arm/include/asm/arch-rockchip',

which is dynamic generate by build system, I thinks there should be some dependency issue?

How to fix this kind of issue?

Thanks,

- Kever
