- [PATCH] ppc32: cleanup AMCC PPC40x eval boards to support U-Boot
-
- Cleanup PPC40x eval boards (bubinga, walnut and sycamore) to support U-Boot
- as bootloader. The OpenBIOS bd_info struct is not used in the kernel
- anymore (only U-Boot now).
-
- uImage (U-Boot) tested on walnut, sycamore and bubinga
- zImage (OpenBIOS) tested on sycamore, bubinga and ebony
