[dpdk-stable] patch 'eal/arm64: fix platform register bit' has been queued to stable release 19.11.9

[Christian Ehrhardt]

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/d973b353810a5103e91ec51685ff08f325c1db4b

Thanks.

[ upstream commit 20c7744f8d333e9388b479b308c8c2a149110703 ]

REG_PLATFORM only uses bit 0 to indicate whether the value retrieved
from hardware matches PLATFORM_STR.
