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)

47d41cc3a1 Add an architecture specific config.h for common defines
We have common defines that we duplicate in various ways.  Having an
arch specific config.h gives us a common location for those defines.

Eventually we should be able to replace this when we have proper
Kconfig support.

65e43a1063 Introduce virt_to_phys()
virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.

However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual
address.

b57ca3e128 Change bd/gd memsize/ram_size to be phys_size_t.
Currently, both are defined as an unsigned long, but
should be phys_size_t. This should result in no real change,
since phys_size_t is currently an unsigned long for all the
default configs.  Also add print_lnum to cmd_bdinfo to deal
with the potentially wider memsize.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

0e15ddd11f POST: replace the LOGBUFF_INITIALIZED flag in gd->post_log_word (1 << 31) with the GD_FLG_LOGINIT flag in gd->flags.
This way we become able to utilize the full post_log_word for POST
activities (overwise, POST ECC, which has 0x8000 ID, could be
erroneously treated as started in post_output_backlog() even if there
was actually no POST ECC run (because of OCM POST failure, for
example).

4d7d6936eb Introduce map_physmem() and unmap_physmem()
map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.

This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

3a197b2fe4 [PATCH v3] Add sync to ensure flash_write_cmd is fully finished
Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.
