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

Thu Jun 4 11:53:33 PDT 2015


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.
