processor -bcm53003 its mips 32 . i am planning to port linux 2.6.27. i got
some reference code to builld cfe bootloader,but i dont know where to start
in that code.
bootloader has to perform these low level initialization

Reset and ROM trap handler vectors
• CPU and FPU initialization
• L1 and L2 Cache initialization
• Multiprocessor initialization
• Memory controller initialization
• PCI and LDT bus configuration
• Environment variables
• Console device initialization
• Bootstrap device initialization
