But since they all have the Chip ID register at the same -location, we can use that to identify the SoC we are running on. - -Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com> -Cc: linux-mips@linux-mips.org -Cc: Maxime Bizon <mbizon@freebox.fr> -Cc: Florian Fainelli <florian@openwrt.org> -Cc: Kevin Cernekee <cernekee@gmail.com> -Patchwork: https://patchwork.linux-mips.org/patch/3955/ -Reviewed-by: Florian Fainelli <florian@openwrt.org> -Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---- - arch/mips/bcm63xx/cpu.c | 20 ++++++++++++-------- - 1 files changed, 12 insertions(+), 8 deletions(-) - ---- a/arch/mips/bcm63xx/cpu.c -+++ b/arch/mips/bcm63xx/cpu.c -@@ -228,17 +228,21 @@ void __init bcm63xx_cpu_init(void) - bcm63xx_irqs = bcm6345_irqs; - break; - case CPU_BMIPS4350: -- switch (read_c0_prid() & 0xf0) { -- case 0x10: -+ if ((read_c0_prid() & 0xf0) == 0x10) { - expected_cpu_id = BCM6358_CPU_ID; - bcm63xx_regs_base = bcm6358_regs_base; - bcm63xx_irqs = bcm6358_irqs; -- break; -- case 0x30: -- expected_cpu_id = BCM6368_CPU_ID; -- bcm63xx_regs_base = bcm6368_regs_base; -- bcm63xx_irqs = bcm6368_irqs; -- break; -+ } else { -+ /* all newer chips have the same chip id location */ -+ u16 chip_id = bcm_readw(BCM_6368_PERF_BASE); -+ -+ switch (chip_id) { -+ case BCM6368_CPU_ID: -+ expected_cpu_id = BCM6368_CPU_ID; -+ bcm63xx_regs_base = bcm6368_regs_base; -+ bcm63xx_irqs = bcm6368_irqs; -+ break; -+ } - } - break; - } |
