Ali Saidi fffae72b45 Fixed serial support in 2.6 (too much work for...)
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

Ali Saidi fd21387149 Linux boots... various fixes to make console work correctly
dev/console.cc:
    commented out code that checks if an interrupt is happening before issuing one
    because they can get lost when linux boots
dev/console.hh:
    added a setPlatform function to set the platform to interrupt
dev/platform.hh:
dev/tsunami.cc:
dev/tsunami.hh:
    Added virtual functions to post console interrupts
dev/tsunami_io.cc:
    allowed a 64bit read of the PIC since we can't do a physical byte read
dev/tsunami_uart.cc:
    moved TsunamiUart to PioDevice
    various little fixes to make linux work
dev/tsunami_uart.hh:
    Made Tsunami_Uart a PIO device
dev/tsunamireg.h:
    added some UART defines and used the ULL macros
kern/linux/linux_system.cc:
    commented out waiting for gdb

dev/pciconfigall.cc:
dev/tsunami_cchip.cc:
dev/tsunami_io.cc:
dev/tsunami_pchip.cc:
    Fix masking of read/write address to get read/write offset
dev/tsunami_uart.cc:
    Fix masking of read/write address to get read/write offset
    Also added add_child call that was missed
dev/tsunami_uart.hh:
    Changed size to 0x8

Ali Saidi 1ded394fc3 Some changes to for linux 2.6.2
dev/pcidev.cc:
    Linux 2.6 writes the latency timer, so it was added to the list of
    allowable writes
dev/tsunami_uart.cc:
dev/tsunami_uart.hh:
    A couple of changes so that the new linux autoconf serial driver thinks
    that the serial port exists and configures it

Ali Saidi b7f44f6e06 Support for Tsunami coming along... RTC, PIC working, UART in progress
dev/tsunami_io.cc:
    PIC, PIT, RTC implementation for tsunami working so far
dev/tsunami_io.hh:
    PIT, PIC, RTC implementation for tlaser working so far
dev/tsunamireg.h:
    Added RTC defines
kern/linux/linux_system.cc:
    wrote cycle frequency into variable so linux doesn't probe for it.
    The support exists, but it takes two seconds of time to do on a real
    machine, so forever in the simulator.
