ARM: Delete netx a second time

2019-07-22T03:03:11+00:00

Commit ceb02dcf676f ARM: delete netx machine deleted
the mach-netx machine. Then eight days later
it was resurrected by SPDX tag fixes. I think.

Taking the liberty to fix some additional debug uart
cruft.

ARM: delete netx machine

2019-05-22T11:55:50+00:00

After discussing with the subarch maintainers and Hilscher,
we concluded that the netx subarchitecture (Netx 100/500)
is no longer maintained or tested, and noone will miss it
if we delete it. So delete it.

There is a newer Netx 4000 architecture which we may see
included at some point, but this will be supported using
the standard multiplatform and devicetree mechanisms and is
easier to develop from scratch.

Pull ARM SoC platform updates from Olof Johansson:
 "SoC updates, mostly refactorings and cleanups of old legacy platforms.

  Major themes this release:

   - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)

   - Moving some of the ep93xx headers around to get it closer to
     multiplatform enabled.

   - Cleanups of Davinci

  This also contains a few patches that were queued up as fixes before
  5.1 but I didn't get sent in before release"

ARM: debug-ll: add default address for digicolor

2019-04-29T06:20:52+00:00

The digicolor platform has three UARTs, but the Kconfig.debug
file explicitly lists port zero as the one to be used for the
console, while not providing any default values.

This can get an automated randconfig build stuck in a loop
waiting for the user to input the number. As we already know
the physical address, this patch provides that number as
default, along with a reasonable default value for the virtual
address.

ARM: fix function graph tracer and unwinder dependencies

2019-04-23T16:28:32+00:00

Naresh Kamboju recently reported that the function-graph tracer crashes
on ARM. The function-graph tracer assumes that the kernel is built with
frame pointers.

We explicitly disabled the function-graph tracer when building Thumb2,
since the Thumb2 ABI doesn't have frame pointers.

We recently changed the way the unwinder method was selected, which
seems to have made it more likely that we can end up with the function-
graph tracer enabled but without the kernel built with frame pointers.

Fix up the function graph tracer dependencies so the option is not
available when we have no possibility of having frame pointers, and
adjust the dependencies on the unwinder option to hide the non-frame
pointer unwinder options if the function-graph tracer is enabled.

Merge tag 'imx-soc-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc

2018-12-12T21:52:48+00:00

i.MX SoC changes for 4.21:
 - An improvement on i.MX debugging options that only defines
   DEBUG_IMX_UART_PORT if needed, so that the option will not be present
   in the kernel config when DEBUG_LL is disabled.
 - Adds the necessary platform support for i.MX7ULP SoC and configures
   power mode to Partial Stop mode 3 with system/bus clock enabled.
   Otherwise the default STOP mode will gate off system/bus clock when
   WFI gets executed on i.MX7ULP.
 - A fix from Arnd on SOC_IMX7ULP option dependency.

ARM: debug-imx: only define DEBUG_IMX_UART_PORT if needed

2018-12-10T00:56:30+00:00

If debugging on i.MX is enabled DEBUG_IMX_UART_PORT defines which UART
is used for the debug output. If however debugging is off don't only
hide the then unused config item but drop it completely by using a
dependency instead of a conditional prompt.

This fixes DEBUG_IMX_UART_PORT being present in the kernel config even
if DEBUG_LL is disabled.
