libfdt: fix error code of fdt_count_strings()

2015-07-20T13:21:47+00:00

Currently, this function returns a positive value on error,
so we never know whether this function has succeeded or failed.

For example, if the given property is not found, fdt_getprop()
returns -FDT_ERR_NOTFOUND, and then this function inverts it,
i.e., returns FDT_ERR_NOTFOUND (=1).

libfdt: fix error code of fdt_get_string_index()

2015-07-20T13:21:47+00:00

As mentioned in the comment block in include/libfdt.h,
fdt_get_string_index() is supposed to return a negative value
on error.

fdt: Fix handling of paths with options in them

2015-04-24T04:54:32+00:00

After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi
builds would no longer boot.

The problem is that stdout-path is now set like this in the upstream dts
files: stdout-path = "serial0:115200n8". The use of options in of-paths,
either after an alias name, or after a full path, e.g. stdout-path =
"/soc@01c00000/serial@01c28000:115200", is standard of usage, but something
which the u-boot dts code so far did not handle.

This commit fixes this, adding support for both path formats.

fdt: Add functions to retrieve strings

2014-10-22T22:56:41+00:00

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.

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.

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

2014-06-19T15:18:42+00:00

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.
