As documented in doc/I2C_Edge_Conditions, adding a
board specific deblocking mechanism via CFG_I2C_INIT_BOARD
for the mgcoge and mgsuvd board.

This code was originally written by Keymile in association
with Anatech and Atmel in 1998. The Code toggels the SCL
until the SCA line goes to HIGH (max. 16 times).
And after this, a start condition is sent.

This is another approach to deblock the I2C Bus. The
soft I2C driver actually sends 9 clocks with SDA High,
and then a stop at the end, to deblock the I2C Bus.

Maybe we should use the approach from Keymile as
the new standard?

If I2C Bus is blocked (see doc/I2C_Edge_Conditions),
it is not possible to get out of this, until the
complete Hardware gets a reset. This new commando
calls again i2c_init (and that calls i2c_init_board
if defined), which will deblock the I2C Bus.

There are two aspects of a TFTP transfer involving timeouts:
1. timeout waiting for initial server reply after sending RRQ
2. timeouts while transferring actual data from the server

Since the upcoming auto-update feature attempts a TFTP download during each
boot, it is undesirable to have a long delay when the TFTP server is not
available. Thus, this commit makes the server timeout (1.) configurable by two
global variables:

TftpRRQTimeoutMSecs
TftpRRQTimeoutCountMax

TftpRRQTimeoutMSecs overrides default timeout when trying to connect to a TFTP
server, TftpRRQTimeoutCountMax overrides default number of connection retries.
The total delay when trying to download a file from a non-existing TFTP server
is TftpRRQTimeoutMSecs x TftpRRQTimeoutCountMax milliseconds.

Timeouts during file transfers (2.) are unaffected.

Enforce millisecond semantics of the first argument to NetSetTimeout() --
the change is transparent for well-behaving boards (CFG_HZ == 1000 and
get_timer() countiing in milliseconds).

Rationale for this patch is to enable millisecond granularity for
network-related timeouts, which is needed for the upcoming automatic
software update feature.

Summary of changes:
- do not scale the first argument to NetSetTimeout() by CFG_HZ
- change timeout values used in the networking code to milliseconds

Change UEC phy interface from GMII to RGMII on MPC8568MDS board

Because on MPC8568MDS, GMII interface is only recommended for 1000Mbps speed,
but RGMII interface can work at 10/100/1000Mbps, and RGMII interface works more stable.

Now both UEC1 and UEC2 can work properly under u-boot.

It is also in consistent with the kernel setting for 8568 UEC phy interface.

When aligning malloc()ed screen_base, invalid offset was added.
This not only caused misaligned result (which did not cause hardware
misbehaviour), but - worse - caused screen_base + smem_len to
be out of malloc()ed space, which in turn caused breakage of
futher malloc()/free() operation.

This patch fixes screen_base alignment.

Also this patch makes memset() that cleans framebuffer to be executed
on first initialization of diu, not only on re-initialization. It looks
correct to clean the framebuffer instead of displaying random garbage;
I believe that was disabled only because that memset caused breakage
of malloc/free described above - which no longer happens with the fix
described above.

Note that we still have a problem when a single NAND device is bigger
than 4 GiB: then the overflow would actually happen earlier, i. e.
when storing the size in nand_info[].size, as nand_info[].size is an
"u_int32_t".
