fdt: Add functions to retrieve strings

2014-10-22T22:56:41Z

Given a device tree node, a property name and an index, the new function fdt_get_string_index() will return in an output argument a pointer to the index'th string in the property's value. The fdt_get_string() is a shortcut for the above with the index being 0. Signed-off-by: Thierry Reding Acked-by: Simon Glass

fdt: Add a function to get the index of a string

2014-10-22T22:56:40Z

Given a device tree node and a property name, the new fdt_find_string() function will look up a given string in the string list contained in the property's value and return its index. Signed-off-by: Thierry Reding Acked-by: Simon Glass

libfdt: Fix segfault when calling fit_check_format() on corrupt FIT images

2014-06-19T15:18:42Z

It has been observed that fit_check_format() will fail when passed a corrupt FIT image. This was tracked down to _fdt_string_eq(): return (strlen(p) == len) && (memcmp(p, s, len) == 0); In the case of a corrupt FIT image one can't depend on 'p' being NULL terminated. I changed it to use strnlen() to fix the issue. Signed-off-by: Tom Rini

libfdt: Implement property iteration functions

2011-07-15T01:10:34Z

For ages, we've been talking about adding functions to libfdt to allow iteration through properties. So, finally, here are some. I got bogged down on this for a long time because I didn't want to expose offsets directly to properties to the callers. But without that, attempting to make reasonable iteration functions just became horrible. So eventually, I settled on an interface which does now expose property offsets. fdt_first_property_offset() and fdt_next_property_offset() are used to step through the offsets of the properties starting from a particularly node offset. The details of the property at each offset can then be retrieved with either fdt_get_property_by_offset() or fdt_getprop_by_offset() which have interfaces similar to fdt_get_property() and fdt_getprop() respectively. No explicit testcases are included, but we do use the new functions to reimplement the existing fdt_get_property() function.

Support ePAPR compliant phandle properties

2011-07-15T01:03:53Z

Currently, the Linux kernel, libfdt and dtc, when using flattened device trees encode a node's phandle into a property named "linux,phandle". The ePAPR specification, however - aiming as it is to not be a Linux specific spec - requires that phandles be encoded in a property named simply "phandle". This patch adds support for this newer approach to dtc and libfdt. Specifically: - fdt_get_phandle() will now return the correct phandle if it is supplied in either of these properties - fdt_node_offset_by_phandle() will correctly find a node with the given phandle encoded in either property. - By default, when auto-generating phandles, dtc will encode it into both properties for maximum compatibility. A new -H option allows either only old-style or only new-style properties to be generated. - If phandle properties are explicitly supplied in the dts file, dtc will not auto-generate ones in the alternate format. - If both properties are supplied, dtc will check that they have the same value. - Some existing testcases are updated to use a mix of old and new-style phandles, partially testing the changes. - A new phandle_format test further tests the libfdt support, and the -H option.
