Subject: [PATCH] ARM: dts: BCM5301X: Specify flash partitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Most devices use Broadcom standard partitions which allows them to be
described with the "brcm,bcm947xx-cfe-partitions". Exceptions are:
1) TP-LINK devices which use "os-image" partition with TRX containing
kernel only + separated rootfs partition.
2) Asus RT-AC87U with custom "asus" partition.
This commit also removes undocumented and unsupported linux,part-probe
binding which got accidentally upstreamed while describing SPI
controller.

Subject: [PATCH] ARM: dts: BCM5301X: Relicense BCM47081/BCM4709 files to the
GPL 2.0+ / MIT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This matches licensing used by other BCM5301X files and is preferred as:
1) GPL 2.0+ makes it clearly compatible with Linux kernel
2) MIT is also permissive but preferred over ISC
Both files were fully developed by me. Commits touching them were signed
by Florian and Hauke due to submitting process only.

/ MIT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This matches licensing used by most of BCM5301X files and is preferred as:
1) GPL 2.0+ makes it clearly compatible with Linux kernel
2) MIT is also permissive but preferred over ISC
This file was fully developed by me.

Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Linksys EA6500 V2
It is wireless home router based on BCM4708A0 with BCM4360 + BCM4331
wireless chipsets. The BCM4331 5GHz chip currently isn't supported only
due to missing compatible firmware.

This driver provides support for Northstar mux controller. It differs
from Northstar Plus one so a new binding and driver were needed.

Subject: [PATCH] usb: xhci: add support for performing fake doorbell
Broadcom's Northstar XHCI controllers seem to need a special start
procedure to work correctly. There isn't any official documentation of
this, the problem is that controller doesn't detect any connected
devices with default setup. Moreover connecting USB device to controller
that doesn't run properly can cause SoC's watchdog issues.
A workaround that was successfully tested on multiple devices is to
perform a fake doorbell. This patch adds code for doing this and enables
it on BCM4708 family.

Subject: [PATCH] ARM: BCM5301X: Disable MMU and Dcache during decompression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Broadcom devices have broken CFE (bootloader) that leaves hardware in an
invalid state. It causes problems with booting Linux. On Northstar
devices kernel was randomly hanging in ~25% of tries during early init.
Hangs used to happen at random places in the start_kernel. On BCM53573
kernel doesn't even seem to start booting.
To workaround this problem we need to do following very early:
1) Clear 2 following bits in the SCTLR register:
#define CR_M (1 << 0) /* MMU enable */
#define CR_C (1 << 2) /* Dcache enable */
2) Flush the whole D-cache
3) Disable L2 cache
Unfortunately this patch is not upstreamable as it does above things
unconditionally. We can't check if we are running on Broadcom platform
in any safe way and doing such hacks with ARCH_MULTI_V7 is unacceptable
as it could break other devices support.

command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some w25q128 chipsets don't support RDID (0x9f) command, they reply with
0xff-s only. To suppose such flashes fallback to the 0x90 command.
