+Subject: [PATCH 1/3] ARM: BCM5301X: initial support for the BCM5301X/BCM470X
+ SoCs with ARM CPU
+
+This patch adds support for the BCM5301X/BCM470X SoCs with an ARM CPUs.
+Currently just booting to a shell is working and nothing else, no
+Ethernet, wifi, flash, ...
+I have some pending patches to make Ethernet work for this device.
+Mostly device tree support for bcma is missing.
+
+This SoC is used in small office and home router with Broadcom SoCs
+it's internal name is Northstar. This code should support the BCM4707,
+BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or
+two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers,
+4 Gigabit Ethernet MACs and a USB 3.0 host controller.
+
+This SoC uses a dual core CPU, but this is currently not implemented.
+More information about this SoC can be found here:
+http://www.anandtech.com/show/5925/broadcom-announces-bcm4708x-and-bcm5301x-socs-for-80211ac-routers

+Subject: [PATCH 3/3] ARM: BCM5301X: workaround suppress fault
+
+Without this patch I am getting a unhandled fault exception like this
+one after "Freeing unused kernel memory":
+
+Freeing unused kernel memory: 1260K (c02c1000 - c03fc000)
+Unhandled fault: imprecise external abort (0x1c06) at 0xb6f89005
+Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000007
+
+The address which is here 0xb6f89005 changes from boot to boot, with a
+new build the changes are bigger. With kernel 3.10 I have also seen
+this fault at different places in the boot process, but starting with
+3.11 they are always occurring after the "Freeing unused kernel memory"
+message. I never was able to completely boot to userspace without this
+handler. The abort code is constant 0x1c06. This fault just happens
+once in the boot process I have never seen it happing twice or more.
+
+I also tried changing the CPSR.A bit to 0 in init_early, with this code
+like Afzal suggested, but that did not change anything:
+asm volatile("mrs r12, cpsr\n"
+	"bic r12, r12, #0x00000100\n"
+	"msr cpsr_c, r12" ::: "r12", "cc", "memory");
+
+Disabling the L2 cache by building with CONFIG_CACHE_L2X0 unset did not
+help.
+
+This workaround was copied from the vendor code including most of the
+comments. It says it they think this is caused by the CFE boot loader
+used on this device. I do not have any access to any datasheet or
+errata document to check this.

+These are some hackish patches to make the Ethernet driver work somehow
+on this arm core.
+The flash driver is not working, so we removed the nvram reading, this 
+should be changed after we have a flash driver.
+The mdelay(1) is a ugly workaround for this arm chip, this seams to be a dma problem.
+
+The PHY says it is not connected by default, just ignore it.
