ARM: mvebu: don't select CONFIG_NEON
CONFIG_NEON is meant to be user-selectable. Turning it on
unconditionally means we can't build a smaller kernel when
we don't need it, and causes build errors if CONFIG_VFP
is not also enabled.
To still have neon enabled however, we need to turn it on
now in multi_v7_defconfig and mvebu_v7_defconfig.

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.

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.

ARM: imx: clk-imx6sl: Suppress duplicate const sparse warning
There should be no duplicate const specifiers for those static
constant character string arrays defined for clock mux options.
Also, the arrays are only taken as the 5th argument for the
imx_clk_mux() function, which is in the type of 'const char
**parents'. So, let's remove the 2nd const specifier right
after 'char'.
This patch fixes these sparse warnings:

Since commit
65aa94b204d (ARM: OMAP4: clockdomain/CM code: Update supported

instead of SW_SLEEP for the idling of clockdomains. However, additional
SoCs now leverage the OMAP4 clockdomain code so update it to use SW_SLEEP
if the clockdomain data specifies that the CLKDM has the
CLKDM_CAN_FORCE_SLEEP flag set rather than using HW_AUTO for both cases.
Without this patch, clockdomain handling is broken on AM43xx and no
clockdomains are actually being put into idle on this platform. Any
attempt to idle them results in the HW_AUTO value (0x3) being written
