From 8545129540a5862b22aad03badb2a9f93bf29117 Mon Sep 17 00:00:00 2001

Subject: [meta-fsl-ppc][PATCH] linux-qoriq: Change defconfig for T1040 to
match number of CPUS
Having a number higher than necessary for NR_CPUS wastes memory by
instantiating unnecessary structures in RAM. An example is in the DPAA where
DPAA_ETH_TX_QUEUES is defined based on NR_CPUS and used to create
dozens of extra qman_fq structures. Using the prior value of 24, which was
left over from the T4240 created an additonal 60 frame queue structures alone.
This has been tested on t1040rdb-64b. .
