Hi Alexey,
ddw_avail is a pointer to the ibm,ddw-applicable property which
contains 3 cells which are big-endian as it is a device tree.
rtas_call() accepts a RTAS token in CPU-endian. This converts RTAS
tokens from big-endian to CPU-endian. Since every token is used once
till guest is
rtas_call() accepts and returns values in CPU endianness.
The ddw_query_response and ddw_create_response structs members are
defined and treated as BE but as they are passed to rtas_call() as
(u32 *) and they get byteswapped automatically, the data is actually
CPU-endian. This fixes
