CCI-500 provides 8 independent event counters, which 45 can count events pertaining to the slave/master interfaces as well 46 as the internal events to the CCI. 47 48 If unsure, say Y 49 50config ARM_CCN 51 bool "ARM CCN driver support" 52 depends on ARM || ARM64 53 depends on PERF_EVENTS 54 help 55 PMU (perf) driver supporting the ARM CCN (Cache Coherent Network) 56 interconnect. 57 58config BRCMSTB_GISB_ARB 59 bool "Broadcom STB GISB bus arbiter" 60 depends on ARM || MIPS 61 help 62 Driver for the Broadcom Set Top Box System-on-a-chip internal bus 63 arbiter. This driver provides timeout and target abort error handling 64 and internal bus master decoding. 65 66config IMX_WEIM 67 bool "Freescale EIM DRIVER" 68 depends on ARCH_MXC 69 help 70 Driver for i.MX WEIM controller. 71 The WEIM(Wireless External Interface Module) works like a bus. 72 You can attach many different devices on it, such as NOR, onenand. 73 74config MIPS_CDMM 75 bool "MIPS Common Device Memory Map (CDMM) Driver" 76 depends on CPU_MIPSR2 77 help 78 Driver needed for the MIPS Common Device Memory Map bus in MIPS 79 cores. This bus is for per-CPU tightly coupled devices such as the 80 Fast Debug Channel (FDC). 81 82 For this to work, either your bootloader needs to enable the CDMM 83 region at an unused physical address on the boot CPU, or else your 84 platform code needs to implement mips_cdmm_phys_base() (see 85 asm/cdmm.h). 86 87config MVEBU_MBUS 88 bool 89 depends on PLAT_ORION 90 help 91 Driver needed for the MBus configuration on Marvell EBU SoCs 92 (Kirkwood, Dove, Orion5x, MV78XX0 and Armada 370/XP). 93 94config OMAP_INTERCONNECT 95 tristate "OMAP INTERCONNECT DRIVER" 96 depends on ARCH_OMAP2PLUS 97 98 help 99 Driver to enable OMAP interconnect error handling driver. 100 101config OMAP_OCP2SCP 102 tristate "OMAP OCP2SCP DRIVER" 103 depends on ARCH_OMAP2PLUS 104 help 105 Driver to enable ocp2scp module which transforms ocp interface 106 protocol to scp protocol.
