What I have seen from BRCM customizations on Samsung phones is that the per-device customization of firmware seems to involve the set-up of some GPIO and power management pins. For example if integrated with an SoC that has autonomous system resume, or if some GPIO line has to be pulled to enable an external regulator or PA. To the best of my knowledge that customization is done by consultants from Broadcom when working with the device manufacturer, and eventually they roll a unique firmware for the device. Probably because the firmware can only be signed for execution by Broadcom? Yours, Linus Walleij
