* x86: set active package and current instance to root device node before probeMark Cave-Ayland2019-08-181-1/+8
| | | | | | | | | Now that all PCI devices have been converted to new-device...finish-device we can set both the active package and current instance to the root device node before probe, giving all child devices a correct active package and instance chain during creation.

* x86: remove static declaration from multiboot_header definitionMark Cave-Ayland2018-01-191-1/+1
| | | | | | | | | | | | Newer versions of gcc fail to compile OpenBIOS giving a "error: ‘multiboot_header’ defined but not used" message when the default build with -Werror enabled is used. Remove the static declaration to enable compilation to succeed, which incidentally matches the other copies of multiboot.c in the OpenBIOS source tree.

* libopenbios: remove address parameter from start_elf()Mark Cave-Ayland2016-09-111-3/+1
| | | | | | | Now that each loader sets up its own context, there is no need to pass in the address or set up the context ourselves. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
* libopenbios: move go() function into libopenbiosMark Cave-Ayland2016-09-113-45/+1
| | | | | | | | | Add an (arch-go) hook for architectures that need to do their own thing before starting an image, and switch the callers over to use it. Also clarify the state-valid check: any non-zero value is considered true. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

* elf: set boot notes in elf_load() if suppliedMark Cave-Ayland2016-09-113-12/+7
| | | | | | | | | | Since the parameter is now already available to arch_init_program(), there is no need to supply it separately to start_elf(). Remove the second parameter and fix up the callers, including standardising the prototype of start_elf() across all architectures. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

* libopenbios: move console selection from compile-time to runtimeMark Cave-Ayland2013-10-252-3/+13
| | | | | | | | | | | | | Some architectures require different console configurations depending upon the machine type. This commit moves the console handlers into a struct _console_ops structure held within libopenbios and switches all our supported architectures over to use it.

* tcx.fs: move framebuffer mapping over from C to tcx.fsMark Cave-Ayland2013-08-191-1/+1
| | | | | | | | | | | Finally we can now fix up setup_video() so that it has no knowledge of fixed addresse but simply refers to the underlying Forth variables as per the specification. Touch up various places as a result of this, but we can now remove the bogus openbios-video-addr and just use frame-buffer-adr instead.

* video_common.c: split video setup routines into setup_video()Mark Cave-Ayland2013-07-271-1/+7
| | | | | | | | | | | | | | | | | Leave per-device work in init_video() for the moment. As part of this commit we fix up switch-arch so that CONFIG_QEMU works for SPARC32 - if we are given the framebuffer information via the QEMU firmware interface we use it. Otherwise fall back to the values of the VGA_DEFAULT_* constants. This commit requires a corresponding patch for QEMU as currently the framebuffer width/height are not passed via the firmware interface for SPARC32.

* Introduce forth_init() for trampoline initializationAndreas Färber2010-11-131-0/+1
| | | | | | | | | | | | | | | | | | | | Use init_trampoline() for trampoline variable initialization. Add calls to a new forth_init() function for each architecture to invoke it. Idea courtesy of Blue. This fixes ppc64 compilation by avoiding a casted self-reference. v2: * Share init_trampoline() with kernel/bootstrap.c, suggested by Mark. * Adopt QEMU coding style for new functions.

* Rework the OpenBIOS internals so that boot, load and init-program now all ↵Mark Cave-Ayland2010-08-011-83/+3
| | | | | | | | | | | | | | | | | | | | | use the unified libopenbios loader code with improved IEEE-1275 spec compliance. This patch implements the following: 1) Fix bootpath/bootargs handling so that default values are read from NVRAM, and allow multiple space-separated values to be specified. 2) With correct bootargs handling in place, move the ELF loader over to the new libopenbios unified loaders. 3) Remove all the loader code from all architecture directories sine we don't need it anymore. 4) Simplify the boot word so it invokes platform-specific code where required, then calls load and go as per the specification. Tested on all my available images for SPARC32, SPARC64 and PPC, and compile-tested on x86.

In order to test the new code, start by switching the Fcode loader over to the new infrastructure for testing on SPARC64.
