Since your board is a Broadwell-U, easiest way will be to extract it (along with the required refcode blob) from the generic/shellball image firmware for a Broadwell-U Chromebook (using cbfstool), which itself can be extracted from a ChromeOS recovery image. John Lewis wrote up some helpful instructions here: https://johnlewis.ie/extracting-the-shell-ball-rom-using-a-chromeos-image/ I'd recommend using the image for 'SAMUS', the Google Chromebook Pixel2.
