Each architecture has different ways of determine what regions of memory
might not be valid to get overwritten when we boot. This provides a
hook to allow them to reserve any regions they care about. Currently
only ppc, m68k and sparc need/use this.

Sub-command can benefit from using the same table and search functions
that top level commands have. Expose this functionality by refactoring
find_cmd() and introducing find_cmd_tbl() that sub-command processing
can call.

The EEprom contains some Manufacturerinformation,
which are read from u-boot at boot time, and saved
in same hush shell variables.
Signed-off-by: Heiko Schocher <hs@denx.de>
This new command shows the local variables defined in
the hush shell:
=> help showvar
showvar
- print values of all hushshell variables
showvar name ...
- print value of hushshell variable 'name'
Also make the set_local_var() and unset_local_var ()
no longer static, so it is possible to define local
hush shell variables at boot time. If CONFIG_HUSH_INIT_VAR
is defined, u-boot calls hush_init_var (), where
boardspecific code can define local hush shell
variables at boottime.

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.

Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC
values. This fixes the occasional 440SPe hard locking issues when the 440SPe's
dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver).
Previously the appropriate initialization had been made in Linux, by the
ppc440spe ADMA driver, which is wrong because modifying the MQ configuration
registers after normal operation has begun is not supported and could
have unpredictable results.
Comment from Stefan: This patch doesn't change the resulting value of the
MQ registers. It explicitly sets/clears all bits to the desired state which
better documents the resulting register value instead of relying on pre-set
default values.
