8d61625d6a x86: Put global data on the stack
Putting global data on the stack simplifies the init process (and makes it
slightly quicker). During the 'flash' stage of the init sequence, global
data is in the CAR stack. After SDRAM is initialised, global data is copied
from CAR to the SDRAM stack

bffe31c144 serial: Remove CONFIG_SERIAL_MULTI from config files
Remove any notion of CONFIG_SERIAL_MULTI from board config files.
Since CONFIG_SERIAL_MULTI is now enabled by default, it is useless
to specify this config option in the board config files. Therefore
remove it.

31a4f1e5b6 board configs: drop NET_MULTI references
Now that none of the core checks CONFIG_NET_MULTI, there's not much point
in boards defining it.  So scrub all references to it.

ec8016c856 eNET: Fix saveenv crash
CONFIG_ENV_SIZE = CONFIG_ENV_SECT_SIZE = 128kB but CONFIG_SYS_STACK_SIZE
is only 32kB resulting in saveenv causing a stack overflow and crashing
U-Boot. Resolve by reducing CONFIG_ENV_SIZE to 4kB

Also fix up CONFIG_SYS_MALLOC_LEN to correctly use environment sector
size and add some comments to the memory organisation configuration

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

24956642ef Remove unused CONFIG_SERIAL_SOFTWARE_FIFO feature
This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.

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.
