* libopenbios: move go() function into libopenbiosMark Cave-Ayland2016-09-111-5/+9
| | | | | | | | | 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>

| | | | | | | The per-arch context is held via __context, so what we hold here is effectively just information about the last loaded file. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
* bootcode_load.c: use new get-bootcode-info plus minor bootcode fixesMark Cave-Ayland2014-03-091-3/+0
| | | | | | | | | | | | | | | | | | Bring the bootcode loader in line with all of the other existing loaders, making use of our new get-bootcode-info word to pass the parameters instead of creating global variables for them all. Here we remove all global variables and references to the fixed load address used by the quik bootcode loader as this is handled by get-bootcode-info. This exposes a minor bug where we need to return success as soon as a valid bootcode is detected; otherwise we inadvertently drop into the filesystem detection code which is invalid. Based upon a patch by Andrei E. Warkentin <andrey.warkentin@gmail.com>.

* load: fix generation of /chosen bootpath propertyMark Cave-Ayland2013-06-281-12/+72
| | | | | | | | | | | | | | | | | | | | | | | It seems that some OS require the bootpath property to be the full, unaliased path to the selected boot device, so use get-instance-path to ensure that this is the case. There is a slight issue here when auto-probing a partition, since the package arguments won't contain the chosen partition id which semms to be mandatory for bootpath. In order to resolve this, scan for a special selected-partition-args property in the instance chain before generating the bootpath, and if it exists use that for the device package arguments instead. Using this mechanism, we can set this property once we have auto-probed a partition in mac-parts.c so bootpath is generated correctly. Finally it is possible to remove the current hack of overwriting bootpath when calling open-dev on a mac-parts partition, which would confuse some bootloaders if they read bootpath after opening a new device.

* loader: implement new loader type for CHRP/Apple partition bootcode (%BOOT)Mark Cave-Ayland2013-04-051-0/+4
| | | | | | | | | | | | | | | | | | | | | One of the primary reasons that issues with the quik bootloader were not detected earlier was because arch/ppc/qemu/main.c has a separate code path for forcing an old-world boot when -boot c is passed to QEMU. This commit implements the bootcode loader as a core OpenBIOS loader which enables old-world payloads such as quik to be executed using: load hd:,%BOOT go Note that we also fix a bug in mac-parts.c to ensure that we don't try and interpose a filesystem package when %BOOT is passed as a filename.

* mac-parts.c: Fix auto-partition selection for the dir word.Mark Cave-Ayland2013-03-221-1/+1
| | | | | | | | | | | | | | | Commit r1100 fixed the quik bootloader but broke automatic partition selection for the dir word. Differentiate between the package having no arguments (argstr == NULL) and the package having empty arguments (argstr == ""), and alter the dir word to use the latter version to invoke the automatic partition selection code when required.

* Improve dir word by reducing complexity and adding some more diagnostics.Mark Cave-Ayland2012-11-241-3/+5
| | | | | | | | | | | Since the OF path resolution algorithm automatically passes anything following a ':' as an argument to the specified device, we don't need to bother with handling this ourselves. As a side effect, the auxiliary word split-path-device is no longer needed as we can isolate the path by doing a simple split on ','.

* Make select-dev and unselect-dev compatible with OBP.Bob Breuer2011-08-081-16/+0
| | | | | | | | | | | | | | | | From the 1275 errata for section H.8, select-dev and unselect-dev are pre Open Firmware, but not the same as open-dev/device-end. Make them Sun OBP compatible by pulling the functionality for select-dev/ unselect-dev out of (and simplifying) begin-package/end-package. For the Sun OBP definition of begin-package/end-package, along with descriptions and example usage, see the "Debugging and Testing FCode Programs" chapter of "Writing FCode 3.x Programs".

| | | | | | | | | | | | | | | | | | | | | 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.
