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.

[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.

Saving the environment leads to overwriting u-boot itself,

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.

For JEDEC flash, we should issue word programming command relative to
base address rather than sector base address. Original source makes
SST Flash fails to program sectors which are not on the 0x10000 boundaries.

e.g.
SST39LF040 uses addr1=0x5555 and addr2=0x2AAA, however, each sector
is 0x1000 bytes.

Thus, if we issue command to "sector base (0x41000) + offset(0x5555)",
it sends to 0x46555 and the chip fails to recognize that address.

This patch is tested with SST39LF040.
