[PATCH/RFC 07/15] ARM: shmobile: r8a7790 dtsi: Add L1 cache information to CPU nodes

From: Geert Uytterhoeven
Date: Thu Jun 04 2015 - 14:53:58 EST


Describe the L1 instruction and data caches in the CPU nodes:
- The L1 caches for the Cortex-A15 CPU cores, and the L1 instruction
caches for the Cortex-A7 CPU cores are organized as 16 KiB x 2
ways,
- The L1 data caches for the Cortex-A7 CPU cores are organized as 8
KiB x 4 ways.
