Add support for newer (up to 2.6.33) kernels Add zboot command which takes the address of a bzImage as its first argument and (optionally) the size of the bzImage as the second argument (the second argument is needed for older kernels which do not include the bzImage size in the header) Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
