This patch adds +support for the following on-chip peripherals: + +- two UARTS +- GPIO +- Ethernet +- SPI +- PCI +- NOR Flash + +The most noticeable difference with 3368 is that it has its peripheral +register at 0xfff8_0000 we check that separately in ioremap.h. Since +3368 is identical to 6358 for its clock and reset bits, we use them +verbatim. + +Signed-off-by: Florian Fainelli <florian@openwrt.org> +Cc: linux-mips@linux-mips.org +Cc: cernekee@gmail.com +Cc: jogo@openwrt.org +Patchwork: https://patchwork.linux-mips.org/patch/5499/ +Signed-off-by: Ralf Baechle <ralf@linux-mips.org> +--- + arch/mips/bcm63xx/Kconfig | 4 + + arch/mips/bcm63xx/clk.c | 18 ++-- + arch/mips/bcm63xx/cpu.c | 28 +++++- + arch/mips/bcm63xx/dev-flash.c | 1 + + arch/mips/bcm63xx/dev-spi.c | 6 +- + arch/mips/bcm63xx/dev-uart.c | 3 +- + arch/mips/bcm63xx/irq.c | 19 ++++ + arch/mips/bcm63xx/prom.c | 4 +- + arch/mips/bcm63xx/reset.c | 29 +++++- + arch/mips/bcm63xx/setup.c | 3 + + arch/mips/include/asm/mach-bcm63xx/bcm63xx_cpu.h | 110 +++++++++++++++++++++ + arch/mips/include/asm/mach-bcm63xx/bcm63xx_gpio.h | 1 + + arch/mips/include/asm/mach-bcm63xx/bcm63xx_regs.h | 45 ++++++++- + arch/mips/include/asm/mach-bcm63xx/ioremap.h | 4 + + arch/mips/pci/pci-bcm63xx.c | 3 +- + 15 files changed, 259 insertions(+), 19 deletions(-) + +--- a/arch/mips/bcm63xx/Kconfig ++++ b/arch/mips/bcm63xx/Kconfig +@@ -1,6 +1,10 @@ + menu "CPU support" + depends on BCM63XX + ++config BCM63XX_CPU_3368 ++ bool "support 3368 CPU" ++ select HW_HAS_PCI ++ + config BCM63XX_CPU_6328 + bool "support 6328 CPU" + select HW_HAS_PCI +--- a/arch/mips/bcm63xx/clk.c ++++ b/arch/mips/bcm63xx/clk.c +@@ -84,7 +84,7 @@ static void enetx_set(struct clk *clk, i + else + clk_disable_unlocked(&clk_enet_misc);
