6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> [ Upstream commit 68c9c53d45fa9c48a89d8a9a4d1555b9e91add69 ] Complete the description of the Cortex-A76 CPU cores and L3 cache controllers on the Renesas R-Car V4H (R8A779G0) SoC, including CPU topology and PSCI support for enabling CPU cores. R-Car V4H has 4 Cortex-A76 cores, grouped in 2 clusters. Based on a patch in the BSP by Takeshi Kihara.
