The previous patch makes u-boot use the full accessible size of ram as
the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined,
which means boot_relocate_fdt() can be changed to depend solely on
CONFIG_OF_LIBFDT.

This patch adds a function getenv_bootm_mapsize() for obtaining the
size of the early mapped region accessible by the kernel during early
boot.  It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined,
defaults to getenv_bootm_size(), which in turn defaults to the size of
RAM.

getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize"
environmental variable.

For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low().  Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.

I ran into a problem where the reset was failing except when I enabled
debugging support.  After talking with Garret Swalling at Spansion I
was told that the GL-N series of devices require a 500ns wait for the
reset to complete.  The below patch adds a 1us delay after all reset

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.

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

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
