The main difference is it supports DT binding. This allows us to use DT
for specifying controller and the new standalone USB 3.0 PHY driver.
Thanks to that we don't need out of tree patch adding PHY initialization
to the controller driver anymore.
This problem has been fixed by upstream commit 757de492f2d ("xhci: fix
platform quirks overwrite regression in 4.7-rc1").

This drops built-in support for USB 2.0 PHY and starts using separated
driver that was upstreamed & backported some time ago.

Previous version was based on code from kernel 2.6.22 with Broadcom two
trivial modifications. This updates the copy to the version from current
kernel and refreshes the patch.
This was tested for regressions on Netgear R6250 (BCM4708A0), D-Link
DIR-885L (BCM4709C0) and Tenda AC9 (BCM47189B0).

Over a year ago in a commit ac96a1665a ("bcm53xx: update Disable MMU
and Dcache during decompression") we switched to Florian's patch for
workarounding CFE bug. The main difference was using a part of existing
__armv7_mmu_cache_flush instead of implementing flushing separately.
This worked well for Northstar devices but doesn't work for BCM53573 as
these devices simply don't start booting with Florian's patch. It's
because of the ldmfd ASM instruction in the __armv7_mmu_cache_flush.
So this commit switches back to using standalone implementation. This
time instead of copying Broadcom's copy of cache-v7.S, we just make a
copy of the original file on our own. Unfortunately we can't cross-dir
compile cache-v7.S from ../../mm/ as that one also adds __INITDATA with
define_cache_functions v7 which would just trigger
> Error: unrecognized/unsupported machine ID (r1 = 0x0000007f).
The only real change Broadcom did in copied .S file was modifying mcr
instruction to use c6 instead of c14. It isn't clear to me if we really
need it, but let's use it for now.
By the way we also update commit message of the
[PATCH] ARM: BCM5301X: Disable MMU and Dcache during decompression
This makes kernel booting on BCM53573 successfully.

It was adding unused variable:

It adds and uses ILP clock that requires some other work (in progress)
for upstreaming it. Other than that it adds a quick fix for bcma to add
serial flash before trying to read SPROM.

It wasn't accepted upstream as there was a discusson on Northstar vs.
BCM53573. Once we get a new ARM arch Kconfig entry it should be
possible to upstream it.

For some time now m25p80 supports 32 MiB flashes and we just needed to
patch spi-nor to support JEDEC incompatible w25q128. Also by switching
to m25p80 we gain accelerated SPI flash reads.
