From f45210d6e7aa600fa0fa96eb67afb37567fd4cce Mon Sep 17 00:00:00 2001 From: Matthew McClintock Date: Mon, 18 Feb 2013 10:02:19 +0000 Subject: [PATCH] powerpc/p1022ds: Add support for NAND and NAND boot using SPL Add defines needed to access NAND, remove second flash bank that is actually connected to NAND. Add nand booting support for P1022DS with hardcoded DDR config using SPL framework from 2011 Signed-off-by: Matthew McClintock Signed-off-by: Jerry Huang Signed-off-by: Jiang Yutang Signed-off-by: Kumar Gala Signed-off-by: Andy Fleming --- board/freescale/common/Makefile | 6 ++ board/freescale/p1022ds/Makefile | 14 +++ board/freescale/p1022ds/law.c | 1 + board/freescale/p1022ds/spl_minimal.c | 129 +++++++++++++++++++++++++ board/freescale/p1022ds/tlb.c | 20 ++-- boards.cfg | 2 + include/configs/P1022DS.h | 132 +++++++++++++++++++++++--- 7 files changed, 284 insertions(+), 20 deletions(-) create mode 100644 board/freescale/p1022ds/spl_minimal.c diff --git a/board/freescale/common/Makefile b/board/freescale/common/Makefile index 75725b49ad..72bb56cac4 100644 --- a/board/freescale/common/Makefile +++ b/board/freescale/common/Makefile @@ -33,10 +33,14 @@ COBJS-$(CONFIG_FSL_CADMUS) += cadmus.o COBJS-$(CONFIG_FSL_VIA) += cds_via.o COBJS-$(CONFIG_FMAN_ENET) += fman.o COBJS-$(CONFIG_FSL_PIXIS) += pixis.o +ifndef CONFIG_SPL_BUILD COBJS-$(CONFIG_FSL_NGPIXIS) += ngpixis.o +endif COBJS-$(CONFIG_FSL_QIXIS) += qixis.o COBJS-$(CONFIG_PQ_MDS_PIB) += pq-mds-pib.o +ifndef CONFIG_SPL_BUILD COBJS-$(CONFIG_ID_EEPROM) += sys_eeprom.o +endif COBJS-$(CONFIG_FSL_SGMII_RISER) += sgmii_riser.o ifndef CONFIG_RAMBOOT_PBL COBJS-$(CONFIG_FSL_FIXED_MMC_LOCATION) += sdhc_boot.o @@ -48,7 +52,9 @@ COBJS-$(CONFIG_MPC8555CDS) += cds_pci_ft.o COBJS-$(CONFIG_MPC8536DS) += ics307_clk.o COBJS-$(CONFIG_MPC8572DS) += ics307_clk.o +ifndef CONFIG_SPL_BUILD COBJS-$(CONFIG_P1022DS) += ics307_clk.o +endif COBJS-$(CONFIG_P2020DS) += ics307_clk.o COBJS-$(CONFIG_P3041DS) += ics307_clk.o COBJS-$(CONFIG_P4080DS) += ics307_clk.o diff --git a/board/freescale/p1022ds/Makefile b/board/freescale/p1022ds/Makefile index c6d3418c16..0eeef05266 100644 --- a/board/freescale/p1022ds/Makefile +++ b/board/freescale/p1022ds/Makefile @@ -11,12 +11,26 @@ include $(TOPDIR)/config.mk LIB = $(obj)lib$(BOARD).o +MINIMAL= + +ifdef CONFIG_SPL_BUILD +ifdef CONFIG_SPL_INIT_MINIMAL +MINIMAL=y +endif +endif + +ifdef MINIMAL + +COBJS-y += spl_minimal.o tlb.o law.o + +else COBJS-y += $(BOARD).o COBJS-y += ddr.o COBJS-y += law.o COBJS-y += tlb.o COBJS-$(CONFIG_FSL_DIU_FB) += diu.o +endif SRCS := $(SOBJS:.o=.S) $(COBJS-y:.o=.c) OBJS := $(addprefix $(obj),$(COBJS-y)) diff --git a/board/freescale/p1022ds/law.c b/board/freescale/p1022ds/law.c index b23b8f9af5..c4398ddff9 100644 --- a/board/freescale/p1022ds/law.c +++ b/board/freescale/p1022ds/law.c @@ -16,6 +16,7 @@ struct law_entry law_table[] = { SET_LAW(CONFIG_SYS_FLASH_BASE_PHYS, LAW_SIZE_256M, LAW_TRGT_IF_LBC), SET_LAW(PIXIS_BASE_PHYS, LAW_SIZE_4K, LAW_TRGT_IF_LBC), + SET_LAW(CONFIG_SYS_NAND_BASE_PHYS, LAW_SIZE_32K, LAW_TRGT_IF_LBC), }; int num_law_entries = ARRAY_SIZE(law_table); diff --git a/board/freescale/p1022ds/spl_minimal.c b/board/freescale/p1022ds/spl_minimal.c new file mode 100644 index 0000000000..8d12fa6c7d --- /dev/null +++ b/board/freescale/p1022ds/spl_minimal.c @@ -0,0 +1,129 @@ +/* + * Copyright 2011 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. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
