Stefan Kristiansson 54bd7c510b openrisc: avoid using function parameter regs in reset vector 
The kernel might be invoked through the reset vector, so to
preserve parameters passed to it, temp regs that are not
in the function parameter range needs to be used.

Stefan Kristiansson dec830189e openrisc: enable passing of flattened device tree pointer 
This patch enables passing a fdt pointer to the kernel.

This makes for the kernel parameter API:

void kernel(unsigned int fdt);

which, in accordance with the OpenRISC ABI results in:
r3 = pointer to fdt
