* [POWERPC] bootwrapper: Add get_path()Scott Wood2007-09-141-0/+1
| | | | | | | | | This will be used by the PlanetCore firmware support to construct a linux,stdout-path from the serial node that it finds. Signed-off-by: Scott Wood <scottwood@freescale.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] bootwrapper: flatdevtree fixesScott Wood2007-09-141-4/+3
| | | | | | | | | | | 1. ft_create_node was returning the internal pointer rather than a phandle. 2. ft_find_device_rel was treating a "top" phandle of NULL as an error, rather than as the root of the tree. The old, absolute ft_find_device is removed, and the relative version is renamed to ft_find_device().

* [POWERPC] bootwrapper: Make ft_get_parent() return a phandle, and NULL if ↵Scott Wood2007-03-161-0/+1
| | | | | | | | | | | | | | | | | already top-level. Most of ft_get_parent() is factored out into __ft_get_parent(), which deals only in internal node pointers. The ft_get_parent() wrapper handles phandle conversion in both directions (previously, ft_get_parent() did not convert its return value). It also now returns NULL as the parent of the toplevel node, rather than just returning the toplevel node again (which made it rather useless in loops).

* [POWERPC] Add flatdevtree sourceMark A. Greer2006-10-231-1/+61
| | | | | | | | | | | | | | Add the latest version of the flatdevtree code and corresponding glue. A phandle table now tracks values returned by ft_find_device(). The value returned by ft_find_device() is a phandle which is really an index into the phandle table. The phandle table contains the address of the corresponding node. When the flat dt is edited/moved, the node pointers in the phandle table are updated accordingly so no phandles kept by the caller become stale. Signed-off-by: Mark A.

* [POWERPC] Start arch/powerpc/boot code reorganizationMark A. Greer2006-09-201-0/+46
This abstracts the operations used in the bootwrapper, and defines the operations needed for the bootwrapper to run on an OF platform. The operations have been divided up into platform ops (platform_ops), firmware ops (fw_ops), device tree ops (dt_ops), and console ops (console_ops). The proper operations will be hooked up at runtime to provide the functionality that you need. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
