[PATCH/RFC 10/15] ARM: shmobile: r8a7794 dtsi: Add L1 cache information to CPU nodes

Thu Jun 4 11:53:36 PDT 2015


Describe the L1 instruction and data caches in the CPU nodes:
  - 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.
