This fixes two bugs with comparison of redundant environment flags on
read.

flag0 and flag1 in fw_env_open() were declared signed instead of
unsigned char breaking BOOLEAN mode "== 0xFF" tests and in INCREMENTAL
mode the wrong environment would be chosen where the flag values are
127 and 128 (either way round). With both flags over 128, both signs
flipped and the logic worked by happy accident.

Also there was a logic bug in the INCREMENTAL test (after signedness was
fixed) in the case flag0=0, flag1=255, env 1 would be incorrectly chosen.

Fix both of these.

The new mdio command doesn't have all of the features of the mii
command, but it provides the necessary read/write primitives, and allows
users to interact with 10G PHYs, and other PHYs which use Clause 45 of
802.3.  This means that the mdio command requires a "Device Address"
argument, though for clause 22 PHYs, the argument can be "-".

The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum.
This meant that drivers which used fsl_phy_enet_if to deal with
PHY interfaces would have to convert between the two (or we would have
to have them mirror each other, and deal with the ensuing maintenance
headache). Instead, we switch all clients of fsl_phy_enet_if over to
phy_interface_t, which should become the standard, anyway.

is ripped out.  The old MDIO driver is split off, and placed in
fsl_mdio.c.  The initialization is modified to initialize the MDIO
driver as well.  The powerpc config file is modified to configure PHYLIB

The tsec driver had a bunch of PHY drivers already written. This
converts them all into PHY Lib drivers, and serves as the first
set of PHY drivers for PHY Lib.

While doing that, cleaned up a number of magic numbers (though
not all of them, as PHY vendors like to keep their numbers as
magical as possible).  Also, noticed that almost all of the
vitesse/cicada PHYs had the same config/parse/startup functions,
so those have been collapsed into one.

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme.  The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

There were a few files which were already using phy_read and phy_write
for their PHY function names.  It's only a few places, and the name
seems most appropriate for the high-level abstraction, so let's
rename the other versions to something more specific.

Also, uec_phy.c had a marvell_init function which I renamed to not
conflict with the one in marvell.c

Lastly, uec_phy.c was putting a space between the phy writing
function names, and the open paren, so I fixed that

This patch changes the large page nand_command() routine to use a word
offset instead of a byte offset. The 'offs' argument gets divided by 2
so that the offset passed to nand_command() is still by byte offset.
Originally, the offset was not shifted and when too high an offset was
requested the nand chip would attempt to read non-existent data.

	    mtd: nand: rearrange ONFI revision checking, add ONFI 2.3

	    In checking for the ONFI revision, the first conditional (for checking
	    "unsupported" ONFI) seems unnecessary.  All ONFI revisions should be
	    backwards-compatible; even if this is not the case on some newer ONFI
	    revision, it should simply fail the second version-checking if-else block
	    (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we
	    move our "unsupported" condition after having checked each bit field.

	    Also, it's simple enough to add a condition for ONFI revision 2.3. Note
	    that this does *NOT* mean we handle all new features of ONFI versions
	    above 1.0.

The omap24xx driver only seems to support devices that have a single subaddress
byte. With these types of devices, the first access in a bus transaction is
usually a write (writes the subaddress) followed by either a read or write to
access the devices registers.

Many such devices will respond to a read as the first access, but there are at
least some that will NACK such a read. (e.g. ADV7180.)

The probe function attempts to detect a devices ACK to a read access only and
fails to find devices that NACK a read.

This commit modifies the probe function to start a write instead. This detects
devices that respond to reads (since they must also respond to writes) as well
as those that only respond to writes. The bus is immediately set to idle after a
(N)ACK avoiding actually writing anything to the device.

The Blackfin gpio command isn't terribly Blackfin-specific.  So generalize
the few pieces into two new optional helpers:
	name_to_gpio() - turn a string name into a GPIO #
	gpio_status() - display current pin bindings (think /proc/gpio)

Once these pieces are pulled out, we can relocate the cmd_gpio.c into the
