Totally agree. Freescale, NXP and TI are all great at documentations etc. Qualcomm and Broadcom and Marvell are all notorious on that regard, in most cases all you can get is a product brief unless you're their top 10 customers, otherwise they probably don't even bother sending you a NDA. Broadcom was bought up, Marvell is going nowhere, Qualcomm is the exception though itself is undercut by MediaTek/Huawei these days heavily, which is probably one major reason for this deal. Really sad to see Qualcomm swallows in NXP/Freescale.
MediaTek has quite a few leaked datasheets out there on various Chinese forums, and so do RDA and some of the other lesser-known SoC makes; I haven't seen the same for Broadcom nor Qualcomm. Maybe it's the different culture ( https://www.bunniestudios.com/blog/?p=4297 ) that facilitates this.
