Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \

Add a function to duplicate a memory region, a little like strdup().

This introduces strlcat, which provides a safer interface than strncat. It
never copies more than its size bytes, including the terminating nul. In
addition, it never reads past dest[size - 1], even if dest is not
nul-terminated.

This also removes the stub for dwc3 now that we have a proper
implementation.

These functions include calls to a memory-allocation routine and so need
to use the system routine when called from a library.

To preserve access to these functions for libraries that need it, such as
SDL, rename these functions within U-Boot.

At present architectures can override strdup() but not strndup(). Use
the same option for both.

Add an implementation of strcspn() which returns the number of initial
characters that do not match any in a rejection list.

This functions works like strchr() but returns the end of the string if
the character is not found. Add an implementation of this.
