* Rewrite i386 interrupt handlingGraeme Russ2009-03-20-418/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) Signed-off-by: Graeme Russ <graeme.russ at gmail.com>
* Moved generic (triple fault) reset codeGraeme Russ2009-01-24-16/+0
| | | | | | | | | | | | 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.

* * Implement new mechanism to export U-Boot's functions to standalonewdenk2003-07-24-27/+0
| | | | | | | | applications: instead of using (PPC-specific) system calls we now use a jump table; please see doc/README.standalone for details * Patch by Dave Westwood, 24 Jul 2003: added support for Unity OS (a proprietary OS)
* * Code cleanup:wdenk2003-06-27-99/+97
| | | | | | | | | - remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)
