From b13e930906b313d787f4dd07fe78b74a3a8c22c4 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Fri, 23 May 2008 20:39:01 +0400 Subject: powerpc/83xx: new board support: MPC8360E-RDK This is patch adds board file, device tree, and defconfig for the new board, made by Freescale Semiconductor Inc. and Logic Product Development. Currently supported: 1. UEC{1,2,7,4}; 2. I2C; 3. SPI; 4. NS16550 serial; 5. PCI and miniPCI; 6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85; 7. Graphics controller, Fujitsu MB86277. Not supported in this patch: 1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM NAND driver); 2. FHCI USB (supported with FHCI driver). 3. QE Serial UCCs (tested to not work with ucc_uart driver, reason unknown, yet); 4. ADC AD7843 (tested to work, but support via device tree depends on major SPI rework, GPIO API, etc); Signed-off-by: Anton Vorontsov Signed-off-by: Kumar Gala --- arch/powerpc/platforms/83xx/Kconfig | 11 ++++ arch/powerpc/platforms/83xx/Makefile | 1 + arch/powerpc/platforms/83xx/mpc836x_rdk.c | 102 ++++++++++++++++++++++++++++++ 3 files changed, 114 insertions(+) create mode 100644 arch/powerpc/platforms/83xx/mpc836x_rdk.c (limited to 'arch/powerpc/platforms/83xx') diff --git a/arch/powerpc/platforms/83xx/Kconfig b/arch/powerpc/platforms/83xx/Kconfig index 583b0c7409c..fe75b2ac3c9 100644 --- a/arch/powerpc/platforms/83xx/Kconfig +++ b/arch/powerpc/platforms/83xx/Kconfig @@ -58,6 +58,17 @@ config MPC836x_MDS help This option enables support for the MPC836x MDS Processor Board. +config MPC836x_RDK + bool "Freescale/Logic MPC836x RDK" + select DEFAULT_UIMAGE + select QUICC_ENGINE + select QE_GPIO + select FSL_GTM + select FSL_LBC + help + This option enables support for the MPC836x RDK Processor Board, + also known as ZOOM PowerQUICC Kit. + config MPC837x_MDS bool "Freescale MPC837x MDS" select DEFAULT_UIMAGE diff --git a/arch/powerpc/platforms/83xx/Makefile b/arch/powerpc/platforms/83xx/Makefile index 76494bed69a..f331fd7dd83 100644 --- a/arch/powerpc/platforms/83xx/Makefile +++ b/arch/powerpc/platforms/83xx/Makefile @@ -8,6 +8,7 @@ obj-$(CONFIG_MPC832x_RDB) += mpc832x_rdb.o obj-$(CONFIG_MPC834x_MDS) += mpc834x_mds.o obj-$(CONFIG_MPC834x_ITX) += mpc834x_itx.o obj-$(CONFIG_MPC836x_MDS) += mpc836x_mds.o +obj-$(CONFIG_MPC836x_RDK) += mpc836x_rdk.o obj-$(CONFIG_MPC832x_MDS) += mpc832x_mds.o obj-$(CONFIG_MPC837x_MDS) += mpc837x_mds.o obj-$(CONFIG_SBC834x) += sbc834x.o diff --git a/arch/powerpc/platforms/83xx/mpc836x_rdk.c b/arch/powerpc/platforms/83xx/mpc836x_rdk.c new file mode 100644 index 00000000000..c10dec4bf17 --- /dev/null +++ b/arch/powerpc/platforms/83xx/mpc836x_rdk.c @@ -0,0 +1,102 @@ +/* + * MPC8360E-RDK board file. + * + * Copyright (c) 2006 Freescale Semicondutor, Inc. + * Copyright (c) 2007-2008 MontaVista Software, Inc. + * + * Author: Anton Vorontsov + * + * 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 "mpc83xx.h" + +static struct of_device_id __initdata mpc836x_rdk_ids[] = { + { .compatible = "simple-bus", }, + {}, +}; + +static int __init mpc836x_rdk_declare_of_platform_devices(void) +{ + return of_platform_bus_probe(NULL, mpc836x_rdk_ids, NULL); +} +machine_device_initcall(mpc836x_rdk, mpc836x_rdk_declare_of_platform_devices); + +static void __init mpc836x_rdk_setup_arch(void) +{ +#ifdef CONFIG_PCI + struct device_node *np; +#endif + + if (ppc_md.progress) + ppc_md.progress("mpc836x_rdk_setup_arch()", 0); + +#ifdef CONFIG_PCI + for_each_compatible_node(np, "pci", "fsl,mpc8349-pci") + mpc83xx_add_bridge(np); +#endif + + qe_reset(); +} + +static void __init mpc836x_rdk_init_IRQ(void) +{ + struct device_node *np; + + np = of_find_compatible_node(NULL, NULL, "fsl,ipic"); + if (!np) + return; + + ipic_init(np, 0); + + /* + * Initialize the default interrupt mapping priorities, + * in case the boot rom changed something on us. + */ + ipic_set_default_priority(); + of_node_put(np); + + np = of_find_compatible_node(NULL, NULL, "fsl,qe-ic"); + if (!np) + return; + + qe_ic_init(np, 0, qe_ic_cascade_low_ipic, qe_ic_cascade_high_ipic); + of_node_put(np); +} + +/* + * Called very early, MMU is off, device-tree isn't unflattened. + */ +static int __init mpc836x_rdk_probe(void) +{ + unsigned long root = of_get_flat_dt_root(); + + return of_flat_dt_is_compatible(root, "fsl,mpc8360rdk"); +} + +define_machine(mpc836x_rdk) { + .name = "MPC836x RDK", + .probe = mpc836x_rdk_probe, + .setup_arch = mpc836x_rdk_setup_arch, + .init_IRQ = mpc836x_rdk_init_IRQ, + .get_irq = ipic_get_irq, + .restart = mpc83xx_restart, + .time_init = mpc83xx_time_init, + .calibrate_decr = generic_calibrate_decr, + .progress = udbg_progress, +}; -- cgit v1.2.3
