The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.
Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

Reset function specific to AMD SC520 microcontroller - Is more of a
'hard reset' that the triple fault.
Requires CONFIG_SYS_RESET_SC520 to be defined in config
I would have liked to add this to a new file (cpu/i386/sc520/reset.c)
but ld requires that a object file in a library arhive MUST contain
at least one function which does not override a weak function (and is
called from outside the object file) in order for that object file to
be extracted from the archive. This would be the only function on the
new file, and hence, will never get linked in.

Moved from interrupts.c to cpu.c and made into a weak function to
allow vendor specific override
Vendor specific CPU reset (like the AMD SC520 MMCR reset) can now be
added to the vendor specific code without the need to remember to
#undef usage of the generic method and if you forget to include your
custom reset method, you will always get the default.

Brings i386 in line with other CPUs with a reset vector and frees up reset.c
for CPU reset functions

Renamed show_boot_progress in assembler init phase to
show_boot_progress_asm to avoid link conflicts with C version

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.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

Hi,
There is a bug in the code of clearing the bss section for processor
i386.(File: cpu/i386/start.S)
In the code, bss_start addr (starting addr of bss section) is put into
the register %eax, but the code which clears the bss section refers to
the addr pointed by %edi.
This patch fixes this bug by putting bss_start into %edi register.

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
applications: instead of using (PPC-specific) system calls we now
use a jump table; please see doc/README.standalone for details
