+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] spi: bcm53xx: simplify reading SPI data
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit makes transfer function use spi_transfer_is_last to
+determine if currently processed transfer is the last one. Thanks to
+that we finally set hardware registers properly and it makes controller
+behave the way it's expected to.
+
+This allows simplifying read function which can now simply start reading
+from the slot 0 instead of the last saved offset. It has been
+successfully tested using spi_write_then_read.
+
+Moreover this change fixes handling messages with two writing transfers.
+It's important for SPI flash devices as their drivers commonly use one
+transfer for a command and another one for data.

+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] PCI: iproc: Disable DMA mapping support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This has been added in commit dd9d4e7498de3 ("PCI: iproc: Add inbound
+DMA mapping support") which causes a crash for bcma case. Function
+pci_dma_range_parser_init calls of_n_addr_cells with a NULL argument
+which causes a NULL pointer dereference.
