Removed bootloader and just wrote command line into linux kernel
base/inifile.cc:
the forked process should not return, it should exit.
dev/tsunami_uart.cc:
dev/tsunami_uart.hh:
The serial port in reality has some delay and linux expects it. This
schedules an interrupt 300 cycles after the transmit instead of
immediately
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
removed boot loader and stuck boot command line in the kernel manually
