Sandbox doesn't actually provide U-Boot access to the machine's physical
memory. Instead it provides a RAM buffer of configurable size, and all
memory accesses are within that buffer. Sandbox memory starts at 0 and
is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer
might produce unpredictable results in the event of an error, and would
expose the host machine's memory architecture to the sandbox U-Boot.

Most U-Boot functions assume that they can just access memory at given
address. For sandbox this is not true.

Add a map_sysmem() call which converts a U-Boot address to a system
address. In most cases this is a NOP, but for sandbox it returns a
pointer to that memory inside the RAM buffer.

To get a U-Boot feature to work correctly within sandbox, you should call
map_sysmem() to get a pointer to the address, and then use that address for
any U-Boot memory accesses.

Implements the tstc() interface for the serial driver.  Multiplexing
the console between the serial port and a keyboard uses a polling
method of checking if characters are available; this means that the
serial console must be non-blocking when attempting to read
characters.

The buffer cannot be changed by this function, so change the buffer
pointer to a const. This allows callers with const pointer to use the

If the NAND is locked tight, commands such as lock and unlock will not
work, but the NAND chip may not report an error.  Check the lock tight
status before attempting such operations so that an error status can be
reported if we know the operation will not succeed.

kmvect1 has a UEC2 connection to the piggy board and a UEC0 connection
to the switch MV88E6122. This switch has a connection to a frontport
ethernet interface. The ethernet port used for network booting is
automatically selected by u-boot. If a Piggy is plugged, the Piggy
port is selected (UEC2, eth1). If the Piggy isn't present, the
Frontport is selected (UEC0, eth0).

The switch reset is connected to a GPIO on the PRIO3 board FPGA (GPIO28)
and released at startup.
