[POWERPC] Remove unused code causing a compile warning

2007-08-15T05:12:50+00:00

AFAICT, nobody is using ft_ordered(), and it causes a build warning
to be generated.  This patch cleans that up by removing the function
and the commented-out code that calls it.

[POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop()

2007-05-17T11:11:13+00:00

ft_set_prop() from flatdevtree.c in the zImage wrapper will either
replace an existing property in the flat device tree, or add a new
property definiion if the given property isn't present.

However, when adding properties, it adds the property definition
immediately before the node's END_NODE tag, potentially after any
subnode definitions for the node.  This confuses the kernel flat tree
parser in prom.c which assumes that all property definitions for a
node come before all subnode definitions.

This patch corrects ft_set_prop() so that it adds new properties
before the first subnode, instead of before the END_NODE tag.

[POWERPC] bootwrapper: Add ft_find_node_by_prop_value().

2007-03-16T04:49:14+00:00

ft_find_node_by_prop_value() finds nodes with the specified
property/value pair.

[POWERPC] bootwrapper: Make ft_get_parent() return a phandle, and NULL if already top-level.

2007-03-16T04:49:11+00:00

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] bootwrapper: Refactor ft_get_prop() into internal and external functions.

2007-03-16T04:49:10+00:00

The property searching part of ft_get_prop is factored out into an
internal __ft_get_prop() which does not deal with phandles and does not
copy the property data.  ft_get_prop() is then a wrapper that does the
phandle translation and copying.

[POWERPC] bootwrapper: Use map_string() instead of lookup_string() in ft_prop().

2007-03-13T10:15:58+00:00

When adding a property, the property name should be added to the string
table if it doesn't already exist.  map_string() does that;
lookup_string() will fail instead.

[POWERPC] bootwrapper: Modify pp, not p, in ft_shuffle().

2007-03-13T10:15:55+00:00

Move the caller's pointer back to match the change in the region's start,
rather than alter a byte of the device tree's content.

[POWERPC] bootwrapper: Preserve the pp pointer in ft_make_space() when calling ft_reorder().

2007-03-13T10:15:52+00:00

The ft_reorder() function may change the start of the region of interest,
so the pointer provided by the caller into that region must be fixed up
to still point to the same datum.
