[PATCH v4 0/4] Add Broadcom North Star 2 support
This patch series adds Broadcom North Star 2 (NS2) SoC support. NS2 is an ARMv8 based SoC and under the Broadcom iProc family. Sorry for tying this with the Broadcom iProc PCIe driver fixes for ARM64. I have to tie them together because iProc PCIe support is enabled by default when ARCH_BCM_IPROC is enabled. Without the fixes in the iProc PCIe driver, enabling CONFIG_ARCH_BCM_IPROC would break the build for arm64 defconfig. Let me know if there's a better way to handle this. This patch series is generated based on v4.2-rc2 and tested on Broadcom NS2 SVK Code available on GITHUB: https://github.com/Broadcom/arm64-linux.git branch is ns2-core-v4 Changes from V3: - Add more paragraph to the iProc PCIe arm64 support patch commit message to explain the change and anticipated future change in more details Changes from V2: - Drop hardcoded earlycon kernel command line paramter in NS2 SVK dts file because 1) earlycon is a debugging feature that can be enabled in the bootloader and should not be enabled by default in the board dts file and 2) of_earlycon should be used and support should be added to 8250 DW driver Changes from V1: - Took Arnd's advice to tweak the location of struct pci_sys_data within struct iproc_pcie. This helps to get rid of most of the CONFIG_ARM wrap in iProc PCIe core driver - Use stdout-path and alias for serial console in NS2 SVK dts - Add all 4 CPU descriptions in NS2 dtsi - Remove "clock-frequency" property in the armv8 timer node so timer frequency can be determined based on readings from CNTFRQ_EL0 - Remove config flag ARCH_BCM_NS2.
