i386: Misc PCI fixups

2009-09-04T19:52:52+00:00

Change PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY (Originally done in
commit ff4e66e93c1a, regressed by commit 6d7f610b09f8)

Cast PCI_ROM_ADDRESS_MASK to u32

Wrap probe_pci_video() call inside #ifdef CONFIG_VIDEO

Change call to pci_find_class() to pci_find_devices(). This is based on a
patch submitted on 1st March 2007 (Patch that fixes the compilation errors
for sc520_cdp board) by mushtaq_k

This patch requires that PCI_VIDEO_VENDOR_ID and PCI_VIDEO_DEVICE_ID be
specified in the board config file.  Dummy values have been added for the
SC520 CDP board to enable compilation, but since I do not have one of these,
I do know what the values should be

Fix sc520 timer interrupt generation

2009-09-04T19:51:56+00:00

The current implementation has the timer being started before the interrupt
handler is installed. It the interrupt occurs before the handler is
installed, the timer interrupt is never reset and the timer stops

i386: Change inline asm global symbols to local

2009-09-04T19:49:48+00:00

gcc 4.3.2 optimiser creates multiple copies of inline asm (who knows why)
Remove use of global names for labels to prevent 'symbol already defined'
errors

Dual-license IBM code contributions

2009-08-09T21:15:33+00:00

It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards.  As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

Factor out SC520 sub-features

2009-03-20T21:39:13+00:00

Moved sub-features of the SC520 code which is currently selectively compiled
using #ifdef out of sc520.c into individual files selectively compiled via
the makefile

Rewrite i386 interrupt handling

2009-03-20T21:39:13+00:00

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)
