[PATCH 0/2] Amlogic fixes for v4.10-rc

[Kevin Hilman]

Arnd, Olof,

A couple more Amlogic fixes for the -rc cycle.  The reserved memory is
updated after some debate/discussion of the first version.  This one
has and ack/review from Andreas who objected to the first version.

[PATCH 1/2] ARM64: dts: meson-gxbb-odroidc2: fix GbE tx link breakage

[Kevin Hilman]

From: Jerome Brunet <jbrunet@baylibre.com>

OdroidC2 GbE link breaks under heavy tx transfer. This happens even if the
MAC does not enable Energy Efficient Ethernet (No Low Power state Idle on
the Tx path). The problem seems to come from the phy Rx path, entering the
LPI state.

Disabling EEE advertisement on the phy prevent this feature to be
negociated with the link partner and solve the issue.

[PATCH 2/2] ARM64: dts: meson-gx: Add firmware reserved memory zones

[Kevin Hilman]

From: Neil Armstrong <narmstrong@baylibre.com>

The Amlogic Meson GXBB/GXL/GXM secure monitor uses part of the memory space,
this patch adds these reserved zones.

Without such reserved memory zones, running the following stress command :
$ stress-ng --vm 16 --vm-bytes 128M --timeout 10s
multiple times:

Could lead to the following kernel crashes :
[   46.937975] Bad mode in Error handler detected on CPU1, code 0xbf000000 -- SError
...
[   47.058536] Internal error: Attempting to execute userspace memory: 8600000f [#3] PREEMPT SMP
...
Instead of the OOM killer.

Is it intentional that this is not a PULL?

Regards,
Andreas

Yes.  For one or two patches, arm-soc maintainers are happy to take
patches.  And in this case, it was especially intentional because these
have a dependency on stuff already in arm-soc fixes, so I wanted them to
be applied directly.

Applied both to fixes, thanks!
