Add simple hwconfig infrastructure
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.

nand_spl: read environment early, when booting from NAND using nand_spl
Currently, when booting from NAND using nand_spl, in the beginning the default
environment is used until later in boot process the dynamic environment is read
out. This way environment variables that must be interpreted early, like the
baudrate or "silent", cannot be modified dynamically and remain at their
default values. Fix this problem by reading out main and redundand (if used)
copies of the environment in the nand_spl code.

Instead of using a #define'd register offset, use a function that
provides the PATA controller's base address.
All the rest of include/mpc512x.h are register offset definitions
which can be eliminated by proper use of C structures.
There are only a few register offsets remaining that are needed in
cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h
which is intended as a temporary workaround only. In a later patch
this file will be removed, too, and then auto-generated from the
respective C structs.

General help message cleanup
Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt

In the result, the user would have to run the "help" command to get

so that this information gets always printed.
Note that this changes the user interface of all commands, but
hopefully to the better.

nvedit: speed up printing of environment
The printing code would check the same environment byte multiple times and
write to the console one byte at a time. For some devices (such as the
Blackfin JTAG console which operates in 8 bytes at a time), this is pretty
damned slow. So create a small 16 byte buffer to fill up and send to puts
as needed. In the process, unify the different print functions, shrink
the resulting code (source and compiled), and avoid excess env reads as
those too can be somewhat expensive depending on the board.

cmd_mtdparts: Move to common handling of FLASH devices via MTD layer
This patch removes all references to the direct CFI FLASH interface
(via flash_info[]). Now that all FLASH types currently handled in
mtdparts are available (if selected, see below) via the MTD infrastructure.
This is NOR, NAND and OneNAND right now. This can be achieved by defining
the following options:
CONFIG_MTD_DEVICE (for all FLASH types)
plus
CONFIG_FLASH_CFI_MTD (for NOR FLASH)
So we need to add those defines to the board config headers currently
using the mtdparts commands. This is done via another patch, so
we shouldn't break mtdparts compatibility.
One big advantage from this solution is that the cmd_mtdparts.c is
*much* cleaner now. Lot's of #ifdef's are removed and the code itself
is smaller. Additionally the newly added MDT concatenation feature
can new be used via the mtdparts infrastructure and therefor via
UBI etc.
