+Subject: [PATCH] ARM: BCM5301X: Add basic dts for BCM53573 based Tenda AC9
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM53573 seems to be low priced alternative for Northstar chipsts. It
+uses single core Cortex-A7 and doesn't have SDU or local (TWD) timer. It
+was also stripped out of independent SPI controller and 2 GMACs.
+
+DTS for Tenda AC9 isn't completed yet. It misses e.g. switch entry (we
+still need some b53 fixes) and probably some clocks. It adds support for
+basic features however and can be improved later.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It was tested by LEDE users, all we need is to adjust clock frequency.
+While we're at it create a separated DTS include file to share code with
+other BCM4709 devices easier.

+Content-Transfer-Encoding: 8bit
+
+Driver for Northstar USB 3.0 PHY has been recently added under the name
+phy-bcm-ns-usb3. Add binding for it into the DT files.
+The only slightly tricky part is BCM47094 which uses different PHY
+version and requires different compatible value.

+Subject: [PATCH] ARM: BCM5301X: Add back handler ignoring external imprecise
+ aborts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since early BCM5301X days we got abort handler that was removed by
+commit 937b12306ea79 ("ARM: BCM5301X: remove workaround imprecise abort
+fault handler"). It assumed we need to deal only with pending aborts
+left by the bootloader. Unfortunately this isn't true for BCM5301X.
+
+When probing PCI config space (device enumeration) it is expected to
+have master aborts on the PCI bus. Most bridges don't forward (or they
+allow disabling it) these errors onto the AXI/AMBA bus but not the
+Northstar (BCM5301X) one.
+
+iProc PCIe controller on Northstar seems to be some older one, without
+a control register for errors forwarding. It means we need to workaround
+this at platform level. All newer platforms are not affected by this
+issue.

+Subject: [PATCH 1/6] ARM: BCM5301X: Enable UART by default for BCM4708(1),
+ BCM4709(4) & BCM53012
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Every device tested so far got UART0 (at 0x18000300) working as serial
+console. It's most likely part of reference design and all vendors use
+it that way.
+
+It seems to be easier to enable it by default and just disable it if we
+ever see a device with different hardware design.

+Subject: [PATCH 5/6] ARM: BCM5301X: Specify all RAM by including an extra
+ block
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The first 128 MiB of RAM can be accessed using an alias at address 0x0.
+
+In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
+(up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
+(hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
+range can't be used. I reproduced this problem on:
+1) Buffalo WZR-600DHP2 (BCM47081)
+2) Netgear R6250 (BCM4708)
+3) D-Link DIR-885L (BCM47094)
+
+So it seems we're forced to access first 128 MiB using alias at 0x0 and
+the rest using real base address + 128 MiB offset which is 0x88000000.

+Subject: [PATCH] ARM: BCM5301X: Set 5 GHz wireless frequency limits on Netgear
+ R8000
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Netgear R8000 is a tri-band home router. It has three BCM43602 chipsets
+two of them for 5 GHz band. Both seem the same and their firmwares
+report the same set of channels. The problem is due to hardware / board
+design there are extra limitations that should be respected.
+
+First PHY should be used for U-NII-2 and U-NII-3. Third PHY should be
+used for U-NII-1. Using them in a different way may result in wireless
+not working or in noticeably reduced performance. Basic version of this
+info was provided by Broadcom employee, then it has been verified by me
+using original vendor firmware (which has limitations hardcoded in UI).
+
+This patch uses recently introduced ieee80211-freq-limit property to
+describe these limitations at DT level.
+
+Referencing PCIe devices in DT required specifying all related bridges.
+Below you can see (a bit complex) PCI tree from R8000 that explains all
+entries that I needed to put in DT.

+
+Setting of_node of master's dev seems to be a common way of letting it
+work nicely with DT. This allows specifying device there instead of
+hardcoding one in the driver code.
+
+This was successfully tested with commit 1b47b98acce2 ("ARM: BCM5301X:

+
+My intention was to release this code under GPL v2 license. For some

+controller on Broadcom bcma SoC") totally missed licensing info.
+MODULE_LICENSE was later added by Axel specifying "GNU Public License
+v2 or later".
+
+This patch clarifies situation by adding a proper header (with Copyright
+line) and adjusting MODULE_LICENSE. It should be acked by every driver
+contributor.

+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.

+Subject: [PATCH] mtd: m25p80: use single SPI message for writing data
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On all 3 tested Northstar devices with following flash memories:
+mx25l6405d (8192 Kbytes)
+mx25l12805d (16384 Kbytes)
+mx25l25635e (32768 Kbytes)
+I noticed writing to be broken. Not a single bit was changed leaving all
+bytes set to 0xff.
+
+This is most likely some problem related to the SPI controller or its
+driver. Using a single SPI message seems to workaround this. Of course
+it's not perfect solution as copying whole data into a new buffer makes
+writing slower.
