int fw_csr_string	(	const u32 *	directory,

fw_csr_string() - reads a string from the configuration ROM : e.g. root directory or unit directory : the key of the preceding directory entry : where to put the string : size of , in bytes

The string is taken from a minimal ASCII text descriptor leaf after the immediate entry with . The string is zero-terminated. Returns strlen(buf) or a negative error code.
