This patch is tested for-
1. Boot from DRAM/NAND flash
2. File transfer using tftp
3. NAND flash read/write/erase
4. Linux kernel and RFS Boot from NAND
5. Enabled USB PHY init for kernel need
6. Boot from USB supported

Note: to boot Kirkwood kernel with USB support,
	you should add "usb start" in the boot sequence

So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

fdt_fixup_esdhc() will either disable or enable eSDHC nodes, and
also will fixup clock-frequency property.

Plus, since DR USB and eSDHC are mutually exclusive, we should
only configure the eSDHC if asked through hwconfig.

This patch adds support for eSDHC on MPC837XERDB boards. The WP
switch doesn't seem to work on RDB boards though, the WP pin is
always asserted (can see the pin state when it's in GPIO mode).

FSL DR USB and FSL eSDHC are mutually exclusive because of pins
multiplexing, so user should specify 'esdhc' or 'dr_usb' options
in the hwconfig environment variable to choose between the
devices.

p.s.
Now we're very close to a monitor len limit (196 bytes left using
gcc-4.2.0), so also increase the monitor len by one sector (64 KB).

This patch implements fdt_fixup_esdhc() function that is used to fixup
the device tree.

The function adds status = "disabled" propery if esdhc pins muxed away,
otherwise it fixups clock-frequency for esdhc nodes.

This patch implements simple hwconfig infrastructure: an
interface for software knobs to control a hardware.

This is very simple implementation, i.e. it is implemented
via `hwconfig' environment variable. Later we could write
some "hwconfig <enable|disable|list>" commands, ncurses
interface for Award BIOS-like interface, and frame-buffer
interface for AMI GUI[1] BIOS-like interface with mouse
support[2].

Current implementation details/limitations:

1. Doesn't support options dependencies and mutual exclusion.
   We can implement this by integrating apt-get[3] into the
   u-boot. But I didn't bother yet.

2. Since we don't implement hwconfig command, i.e. we're working
   with the environement directly, there is no way to tell that
   toggling a particular option will need a reboot to take
   an effect. So, for now it's advised to always reboot the
   target after modifying hwconfig variable.

3. We support hwconfig options with arguments. For example,

   set hwconfig dr_usb:mode=peripheral,phy_type=ulpi

   That means:
   - dr_usb - enable Dual-Role USB controller;
   - dr_usb:mode=peripheral - USB in Function mode;
   - dr_usb:phy_type=ulpi - USB should work with ULPI PHYs;

The purpose of this simple implementation is to define some
internal API and then we can continue improving user experience
by adding more mature interface, like hwconfig command with
bells and whistles. Or not adding, if we feel that current
interface fits its needs.

[1] http://en.wikipedia.org/wiki/American_Megatrends
[2] Regarding ncurses and GUI with mouse support -- I'm just
    kidding.
[3] The comment regarding apt-get is also a joke, meaning that
    dependency tracking could be non-trivial. For example, for
    enabling HW feature X we may need to disable Y, and turn Z
    into reduced mode (like RMII-only interface for ethernet,
    no MII).

    It's quite trivial to implement simple cases though.

Now that we have 3 boards for the MPC512x it turns out that they all
use the very same fixed_sdram() code.

This patch factors out this common code into cpu/mpc512x/fixed_sdram.c
and adds a new header file, include/asm-ppc/mpc512x.h, with some
macros, inline functions and prototype definitions specific to MPC512x
systems.

The KSEG1ADDR macro used to be necessary for the RTL8139 Ethernet
driver, but the code that used that macro was removed over a year
ago, so board configuration files no longer need to define it.

The _IO_BASE macro is also automatically defined to 0 if it isn't
already set, so there's no need to define that macro either in the
board configuration files.
