Hi Chen,
The source code to boot.arm is in system/arm/bootloader it's a very simple bootloader that just puts enough stuff in registers for the kernel to start. I haven' tried Linux 3.7, but we trap udelay so that we can skip the function in the simulator and just account for the time rather than simulating a busy loop. You can safely comment out that code, os try to determine what the symbol has changed to in 3.7.
