From 6c0b45d1ceb13cb409f8d62d712d6f0c44feab6c Mon Sep 17 00:00:00 2001 From: Andrew Thoelke Date: Fri, 20 Jun 2014 00:36:14 +0100 Subject: Correctly dimension the PSCI aff_map_node array The array of affinity nodes is currently allocated for 32 entries with the PSCI_NUM_AFFS value defined in psci.h. This is not enough for large systems, and will substantially over allocate the array for small systems. This patch introduces an optional platform definition PLATFORM_NUM_AFFS to platform_def.h. If defined this value is used for PSCI_NUM_AFFS, otherwise a value of two times the number of CPU cores is used. The FVP port defines PLATFORM_NUM_AFFS to be 10 which saves nearly 1.5KB of memory.
