From: Shaveta Leekha Date: Fri, 5 Apr 2013 06:33:51 +0000 (+0530) Subject: powerpc/fsl-booke: Add B4_QDS board support X-Git-Tag: firefly_0821_release~3680^2~603^2~26^2~8 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=af7837c78d789d1d9972a52f0c5ad8c955d6b53e;p=firefly-linux-kernel-4.4.55.git powerpc/fsl-booke: Add B4_QDS board support - Add support for B4 board in board file b4_qds.c, It is common for B4860, B4420 and B4220QDS as they share same QDS board - Add B4QDS support in Kconfig and Makefile B4860QDS is a high-performance computing evaluation, development and test platform supporting the B4860 QorIQ Power Architecture processor, with following major features: - Four dual-threaded e6500 Power Architecture processors organized in one cluster-each core runs up to 1.8 GHz - Two DDR3/3L controllers for high-speed memory interface each runs at up to 1866.67 MHz - CoreNet fabric that fully supports coherency using MESI protocol between the e6500 cores, SC3900 FVP cores, memories and external interfaces. - Data Path Acceleration Architecture having FMAN, QMan, BMan, SEC 5.3 and RMAN - Large internal cache memory with snooping and stashing capabilities - Sixteen 10-GHz SerDes lanes that serve: - Two SRIO interfaces. Each supports up to 4 lanes and a total of up to 8 lanes - Up to 8-lanes Common Public Radio Interface (CPRI) controller for glue-less antenna connection - Two 10-Gbit Ethernet controllers (10GEC) - Six 1G/2.5-Gbit Ethernet controllers for network communications - PCI Express controller - Debug (Aurora) - Various system peripherals B4420 and B4220 have some differences in comparison to B4860 with fewer core/clusters(both SC3900 and e6500), fewer DDR controllers, fewer serdes lanes, fewer SGMII interfaces and reduced target frequencies. Key differences between B4860 and B4420: B4420 has: - Fewer e6500 cores: 1 cluster with 2 e6500 cores - Fewer SC3900 cores/clusters: 1 cluster with 2 SC3900 cores per cluster - Single DDRC @ 1.6GHz - 2 X 4 lane serdes - 3 SGMII interfaces - no sRIO - no 10G Key differences between B4860 and B4220: B4220 has: - Fewer e6500 cores: 1 cluster with 1 e6500 core - Fewer SC3900 cores/clusters: 1 cluster with 2 SC3900 cores per cluster - Single DDRC @ 1.33GHz - 2 X 2 lane serdes - 2 SGMII interfaces - no sRIO - no 10G Signed-off-by: Shaveta Leekha Signed-off-by: Kumar Gala --- diff --git a/arch/powerpc/platforms/85xx/Kconfig b/arch/powerpc/platforms/85xx/Kconfig index 31dc0668a8ec..8f02b05f4c96 100644 --- a/arch/powerpc/platforms/85xx/Kconfig +++ b/arch/powerpc/platforms/85xx/Kconfig @@ -321,6 +321,23 @@ config T4240_QDS help This option enables support for the T4240 QDS board +config B4_QDS + bool "Freescale B4 QDS" + select DEFAULT_UIMAGE + select E500 + select PPC_E500MC + select PHYS_64BIT + select SWIOTLB + select GENERIC_GPIO + select ARCH_REQUIRE_GPIOLIB + select HAS_RAPIDIO + select PPC_EPAPR_HV_PIC + help + This option enables support for the B4 QDS board + The B4 application development system B4 QDS is a complete + debugging environment intended for engineers developing + applications for the B4. + endif endif # FSL_SOC_BOOKE diff --git a/arch/powerpc/platforms/85xx/Makefile b/arch/powerpc/platforms/85xx/Makefile index 712e23313bb6..2eab37ea4a9d 100644 --- a/arch/powerpc/platforms/85xx/Makefile +++ b/arch/powerpc/platforms/85xx/Makefile @@ -23,6 +23,7 @@ obj-$(CONFIG_P4080_DS) += p4080_ds.o corenet_ds.o obj-$(CONFIG_P5020_DS) += p5020_ds.o corenet_ds.o obj-$(CONFIG_P5040_DS) += p5040_ds.o corenet_ds.o obj-$(CONFIG_T4240_QDS) += t4240_qds.o corenet_ds.o +obj-$(CONFIG_B4_QDS) += b4_qds.o corenet_ds.o obj-$(CONFIG_STX_GP3) += stx_gp3.o obj-$(CONFIG_TQM85xx) += tqm85xx.o obj-$(CONFIG_SBC8548) += sbc8548.o diff --git a/arch/powerpc/platforms/85xx/b4_qds.c b/arch/powerpc/platforms/85xx/b4_qds.c new file mode 100644 index 000000000000..0c6702f8b88e --- /dev/null +++ b/arch/powerpc/platforms/85xx/b4_qds.c @@ -0,0 +1,102 @@ +/* + * B4 QDS Setup + * Should apply for QDS platform of B4860 and it's personalities. + * viz B4860/B4420/B4220QDS + * + * Copyright 2012 Freescale Semiconductor Inc. + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the + * Free Software Foundation; either version 2 of the License, or (at your + * option) any later version. + */ + +#include +#include +#include +#include +#include +#include + +#include +#include +#include +#include +#include +#include +#include + +#include +#include +#include +#include + +#include "corenet_ds.h" + +/* + * Called very early, device-tree isn't unflattened + */ +static int __init b4_qds_probe(void) +{ + unsigned long root = of_get_flat_dt_root(); +#ifdef CONFIG_SMP + extern struct smp_ops_t smp_85xx_ops; +#endif + + if ((of_flat_dt_is_compatible(root, "fsl,B4860QDS")) || + (of_flat_dt_is_compatible(root, "fsl,B4420QDS")) || + (of_flat_dt_is_compatible(root, "fsl,B4220QDS"))) + return 1; + + /* Check if we're running under the Freescale hypervisor */ + if ((of_flat_dt_is_compatible(root, "fsl,B4860QDS-hv")) || + (of_flat_dt_is_compatible(root, "fsl,B4420QDS-hv")) || + (of_flat_dt_is_compatible(root, "fsl,B4220QDS-hv"))) { + ppc_md.init_IRQ = ehv_pic_init; + ppc_md.get_irq = ehv_pic_get_irq; + ppc_md.restart = fsl_hv_restart; + ppc_md.power_off = fsl_hv_halt; + ppc_md.halt = fsl_hv_halt; +#ifdef CONFIG_SMP + /* + * Disable the timebase sync operations because we can't write + * to the timebase registers under the hypervisor. + */ + smp_85xx_ops.give_timebase = NULL; + smp_85xx_ops.take_timebase = NULL; +#endif + return 1; + } + + return 0; +} + +define_machine(b4_qds) { + .name = "B4 QDS", + .probe = b4_qds_probe, + .setup_arch = corenet_ds_setup_arch, + .init_IRQ = corenet_ds_pic_init, +#ifdef CONFIG_PCI + .pcibios_fixup_bus = fsl_pcibios_fixup_bus, +#endif +/* coreint doesn't play nice with lazy EE, use legacy mpic for now */ +#ifdef CONFIG_PPC64 + .get_irq = mpic_get_irq, +#else + .get_irq = mpic_get_coreint_irq, +#endif + .restart = fsl_rstcr_restart, + .calibrate_decr = generic_calibrate_decr, + .progress = udbg_progress, +#ifdef CONFIG_PPC64 + .power_save = book3e_idle, +#else + .power_save = e500_idle, +#endif +}; + +machine_arch_initcall(b4_qds, corenet_ds_publish_devices); + +#ifdef CONFIG_SWIOTLB +machine_arch_initcall(b4_qds, swiotlb_setup_bus_notifier); +#endif
