#     powerpc/85xx: Get twr_p102x to compile again
#     
#     With CONFIG_QUICC_ENGINE enabled and CONFIG_UCC_GETH + CONFIG_SERIAL_QE
#     disabled we have an unused variable (np). The code won't compile with
#     -Werror.
#     
#     Move the np variable to the block where it is actually used.

WARNING: vmlinux.o(.text+0x2ac8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
