This supports SMP Linux running on the BCM3384 Zephyr (BMIPS5000) application processor, with fully functional UART and USB 1.1/2.0. Device Tree is used to configure the following items: - All peripherals - Early console base address - SMP or UP mode - MIPS counter frequency - Memory size / regions - DMA offset - Kernel command line The DT-enabled bootloader and build instructions are posted at https://github.com/Broadcom/aeolus Signed-off-by: Kevin Cernekee <cernekee@xxxxxxxxx> --- arch/mips/Kbuild.platforms | 1 + arch/mips/Kconfig | 26 +++ arch/mips/bcm3384/Makefile | 1 + arch/mips/bcm3384/Platform | 7 + arch/mips/bcm3384/dma.c | 81 +++++++++ arch/mips/bcm3384/irq.c | 193 +++++++++++++++++++++ arch/mips/bcm3384/setup.c | 97 +++++++++++ arch/mips/boot/dts/Makefile | 1 + arch/mips/boot/dts/bcm3384.dtsi | 109 ++++++++++++ arch/mips/boot/dts/bcm93384wvg.dts | 32 ++++ arch/mips/configs/bcm3384_defconfig | 78 +++++++++ arch/mips/include/asm/mach-bcm3384/dma-coherence.h | 48 +++++ arch/mips/include/asm/mach-bcm3384/war.h | 24 +++ 13 files changed, 698 insertions(+) create mode 100644 arch/mips/bcm3384/Makefile create mode 100644 arch/mips/bcm3384/Platform create mode 100644 arch/mips/bcm3384/dma.c create mode 100644 arch/mips/bcm3384/irq.c create mode 100644 arch/mips/bcm3384/setup.c create mode 100644 arch/mips/boot/dts/bcm3384.dtsi create mode 100644 arch/mips/boot/dts/bcm93384wvg.dts create mode 100644 arch/mips/configs/bcm3384_defconfig create mode 100644 arch/mips/include/asm/mach-bcm3384/dma-coherence.h create mode 100644 arch/mips/include/asm/mach-bcm3384/war.h diff --git a/arch/mips/Kbuild.platforms b/arch/mips/Kbuild.platforms index f5e18bf..7c50721 100644 --- a/arch/mips/Kbuild.platforms +++ b/arch/mips/Kbuild.platforms @@ -3,6 +3,7 @@ platforms += alchemy platforms += ar7 platforms += ath79 +platforms += bcm3384 platforms += bcm47xx platforms += bcm63xx platforms += cavium-octeon diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index 38e02e1..1c277d5 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -115,6 +115,32 @@ config ATH79 help Support for the Atheros AR71XX/AR724X/AR913X SoCs. +config BCM3384 + bool "Broadcom BCM3384 based boards" + select BOOT_RAW + select NO_EXCEPT_FILL + select USE_OF + select CEVT_R4K + select CSRC_R4K + select SYNC_R4K + select COMMON_CLK + select DMA_NONCOHERENT + select IRQ_CPU + select SYS_SUPPORTS_32BIT_KERNEL + select SYS_SUPPORTS_BIG_ENDIAN + select SYS_SUPPORTS_HIGHMEM + select SYS_HAS_CPU_BMIPS5000 + select SWAP_IO_SPACE + select USB_EHCI_BIG_ENDIAN_DESC + select USB_EHCI_BIG_ENDIAN_MMIO + select USB_OHCI_BIG_ENDIAN_DESC + select USB_OHCI_BIG_ENDIAN_MMIO + help + Support for BCM3384 based boards.
