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:

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.

Subject: [PATCH 6/8] bcma: register bcma as device tree driver
|
||||
|
||||
This driver is used by the bcm53xx ARM SoC code.Now it is possible to
|
||||
give the address of the chipcommon core in device tree.

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.
