The u-boot changes for Arndale-Octa was done as part of an activity
within Linaro. Insignal had signed the SPL binary for us. You can
extract the signed SPL binary from following hwpack[6] (tar xfz and then
within u_boot folder[7]).

The source code for this u-boot can be found here.[8]

Just in case, commands to flash u-boot binaries are listed here.[9]

Adding Arndale-Octa support to upstream U-Boot was on a TODO list, but
that didn't materialize because of some other reasons.
