Ok, I've updated the diff:

	https://github.com/thorpej/netbsd-src/pull/30/files

It now includes the input-block-size and input-pad-size directives I proposed to address the RockChip SPI loader's needs.  You'd use it like so:

                <key>u-boot-install-spi</key>
                <array>
                        <dict>
                                <key>file-name</key>
                                <string>u-boot-sunxi-with-spl.bin</string>
                                <key>output-size</key>
                                <integer>2097152</integer>
                                <key>output-block-size</key>
                                <integer>65536</integer>
                                <key>input-block-size</key>
                                <integer>2048</integer>
                                <key>input-pad-size</key>
                                <integer>2048</integer>
                        </dict>
                </array>

...and the verbose mode output looks like this:
