Change return values of init() functions in all Ethernet drivers to conform
to the following:
>=0: Success
<0: Failure
All drivers going forward should return 0 on success. Current drivers that
return 1 on success were left as-is to minimize changes.

This patch fixes several issues at least on a MPC885 based system with two
FEC interfaces used in MII mode.
1. PHY discovery should first read PHY_PHYIDR2 register and only then
PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it,
otherwise the values read are wrong. Also notice, that PHY discovery
cannot work on MPC88x / MPC87x in setups with both FECs active at all
in its present form, because for both interfaces the registers from FEC
1 are used to communicate over MII.
2. Remove code duplication for resetting the FEC by isolating it into a
separate function.
3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init().
4. Optimize mii_init() to only reset the FEC 1 controller once.
5. Fix a typo in mii_init() using index i instead of j thus potentially
leading to unpredictable results.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

All MII configuration is done via FEC1 registers. But MII_SPEED was
configured according to FEC used. So if only FEC2 was used, this caused
the real MII_SPEED register in FEC1 to stay uninitalised, what lead
to "mii_send STUCK!" messages. Fix: always configure MII_SPEED on FEC1
only.
- Rename DUET_ADS to MPC885ADS
- Rename CONFIG_DUET to CONFIG_MPC885_FAMILY
- Rename CONFIG_866_et_al to CONFIG_MPC866_FAMILY
- Clean up FADS family port to use the new defines
- add support for a new version of an Intracom board and fix
various other things on others.
- add verify support to the crc32 command (define
CONFIG_CRC32_VERIFY to enable it)
- fix FEC driver for MPC8xx systems:
1. fix compilation problems for boards that use dynamic
allocation of DPRAM
2. shut down FEC after network transfers
- HUSH parser fixes:
1. A new test command was added. This is a simplified version of
the one in the bourne shell.
2. A new exit command was added which terminates the current
executing script.
3. Fixed handing of $? (exit code of last executed command)
Improve and fix various things in the MPC8xx FEC driver:
1. The new 87x and 88x series of processors have two FECs,
and the new driver supports them both.
2. Another change in the 87x/88x series is support for
the RMII (Reduced MII) interface. However numerous
changes are needed to make it work since the PHYs
are connected to the same lines. That means that
you have to address them correctly over the MII
interface.

* Patch by Nye Liu, 16 July 2003:
MPC860FADS fixes:
- add MPC86xADS support (uses MPC86xADS.h)
- add 866P/T core support (also MPC859T/MPC859DSL/MPC852T)
o PLPRCR changes
