f3a8d6b29b Fix environment configuration for eNET board
The current configuration of the Environment has the redundant copy of the
environment in the Boot Flash - This was never the intent. The Environment
should instead be in the first two sectors of the first Strata Flash

74de7aefd7 Add "source" command; prepare removal of "autoscr" command
According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.

This patch prepares this change and starts a 6 month transition
period as follows:

- The new "source" command has been added, which implements exactly
  the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
  new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
  have *not* been adapted yet; these will be renamed resp. removed in
  a separate patch when the support for the "autoscr" command get's
  finally dropped.

abf0cd3dff Rewrite i386 interrupt handling
Rewrite interrupt handling functionality for the i386 port. Separated
functionality into separate CPU and Architecture components.

It appears as if the i386 interrupt handler functionality was intended
to allow multiple handlers to be installed for a given interrupt.
Unfortunately, this functionality was not fully implemented and also
had the problem that irq_free_handler() does not allow the passing
of the handler function pointer and therefore could never be used to
free specific handlers that had been installed for a given IRQ.

There were also various issues with array bounds not being fully
tested.

I had two objectives in mind for the new implementation:

1) Keep the implementation as similar as possible to existing
   implementations. To that end, I have used the leon2/3
   implementations as the reference

2) Seperate CPU and Architecture specific elements. All specific i386
   interrupt functionality is now in cpu/i386/ with the high level
   API and architecture specific code in lib_i386. Functionality
   specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has
   been further split out into an individual file to allow for the
   implementation of the PIC architecture of the SC520 CPU (supports
   more IRQs)

bdab39d358 rename CONFIG_CMD_ENV to CONFIG_CMD_SAVEENV
The CONFIG_CMD_ENV option controls enablement of the `saveenv` command
rather than a generic "env" command, or anything else related to the
environment.  So, let's make sure the define is named accordingly.
