Cover letter [PATCH 0/6] ARM: Add support for Broadcom BCM476x SoCs
Quoted 7 lines · Domenico Andreoli
Howdy,
this patchset adds (minimal) support for the Broadcom BCM476x ARM based
SoCs to the kernel, not to be confused with the already supported MIPS based BCM47xx SoC and other BCM47xx WiFi and GPS produced by Broadcom.This BCM476x is a DT-only multi-platform ARM platform and, at this spin,
Nice. I was planning on converting bcm2835 to multi-platform in 3.8; I assume it'll be pretty simple.

Additional support is being worked on.... and usb (DWC OTG) only attemped reusing s3c-hsotg.
Hmmm. I believe the bcm2835 uses DWC OTG. I wonder if the same driver will work there; USB in particular is a major pain point on the bcm2835...

It's based on a random pre v3.7-rc1 commit (eb0ad9c) with mainlined multi-platform support and Stephen's patch to add
DEBUG_LLto it.
There are two chunks of code related to that; uncompress.h and debug-macro.S. Rob/Arnd's multi-platform patches already allowed debug-macro.S to exist after multi-platform conversion, and my patches were about adding back support for uncompress.h. Given that the only reason I cared about uncompress was that Tegra's uncompress.h and debug-macro.s were closely coupled, and Nicolas Pitre indicated he thought that was a hack, I've re-written the Tegra code so they aren't coupled any more (this will be included in 3.8) and so I care much less about uncompress.h now. Unless anyone really pipes up and says they'd still like me to pursue uncompress.h in multi-platform, I'm inclined to drop it.

Special thanks go to Stephen Warren who, with the recently mainlined BCM2835, showed how to do things cleanly since the beginning and involuntarily spurred me to act.
Thanks! Do note that much of the code I upstreamed was originally written by others, although I did make quite a few changes during upstream submission.
