From 1cb19fbb31dc7fd2c3a15667c60c6296d392f96c Mon Sep 17 00:00:00 2001 From: York Sun Date: Thu, 27 Jun 2013 10:48:29 -0700 Subject: powerpc/T4240EMU: Add T4240EMU target Add emulator support for T4240. Emulator has limited peripherals and interfaces. Difference between emulator and T4240QDS includes: ECC for DDR is disabled due the procedure to load images No board FPGA (QIXIS) NOR flash has 32-bit port for higher loading speed IFC and I2C timing don't really matter, so set them fast No ethernet Signed-off-by: York Sun --- board/freescale/t4qds/Makefile | 3 +- board/freescale/t4qds/ddr.c | 73 +--- board/freescale/t4qds/ddr.h | 122 ++++++ board/freescale/t4qds/law.c | 2 + board/freescale/t4qds/t4240emu.c | 96 +++++ board/freescale/t4qds/t4240qds.c | 854 +++++++++++++++++++++++++++++++++++++++ board/freescale/t4qds/t4qds.c | 837 -------------------------------------- board/freescale/t4qds/tlb.c | 2 + 8 files changed, 1079 insertions(+), 910 deletions(-) create mode 100644 board/freescale/t4qds/ddr.h create mode 100644 board/freescale/t4qds/t4240emu.c create mode 100644 board/freescale/t4qds/t4240qds.c delete mode 100644 board/freescale/t4qds/t4qds.c (limited to 'board') diff --git a/board/freescale/t4qds/Makefile b/board/freescale/t4qds/Makefile index 85df066906..a2167b377b 100644 --- a/board/freescale/t4qds/Makefile +++ b/board/freescale/t4qds/Makefile @@ -8,7 +8,8 @@ include $(TOPDIR)/config.mk LIB = $(obj)lib$(BOARD).o -COBJS-y += $(BOARD).o +COBJS-$(CONFIG_T4240QDS) += t4240qds.o +COBJS-$(CONFIG_T4240EMU) += t4240emu.o COBJS-y += ddr.o COBJS-$(CONFIG_T4240QDS)+= eth.o COBJS-$(CONFIG_PCI) += pci.o diff --git a/board/freescale/t4qds/ddr.c b/board/freescale/t4qds/ddr.c index 058d62511f..26ac2a54d2 100644 --- a/board/freescale/t4qds/ddr.c +++ b/board/freescale/t4qds/ddr.c @@ -13,81 +13,10 @@ #include #include #include +#include "ddr.h" DECLARE_GLOBAL_DATA_PTR; -struct board_specific_parameters { - u32 n_ranks; - u32 datarate_mhz_high; - u32 rank_gb; - u32 clk_adjust; - u32 wrlvl_start; - u32 wrlvl_ctl_2; - u32 wrlvl_ctl_3; - u32 cpo; - u32 write_data_delay; - u32 force_2T; -}; - -/* - * This table contains all valid speeds we want to override with board - * specific parameters. datarate_mhz_high values need to be in ascending order - * for each n_ranks group. - */ -static const struct board_specific_parameters udimm0[] = { - /* - * memory controller 0 - * num| hi| rank| clk| wrlvl | wrlvl | wrlvl | cpo |wrdata|2T - * ranks| mhz| GB |adjst| start | ctl2 | ctl3 | |delay | - */ - {2, 1350, 4, 4, 8, 0x0809090b, 0x0c0c0d0a, 0xff, 2, 0}, - {2, 1350, 0, 5, 7, 0x0709090b, 0x0c0c0d09, 0xff, 2, 0}, - {2, 1666, 4, 4, 8, 0x080a0a0d, 0x0d10100b, 0xff, 2, 0}, - {2, 1666, 0, 5, 7, 0x080a0a0c, 0x0d0d0e0a, 0xff, 2, 0}, - {2, 1900, 0, 4, 8, 0x090a0b0e, 0x0f11120c, 0xff, 2, 0}, - {2, 2140, 0, 4, 8, 0x090a0b0e, 0x0f11120c, 0xff, 2, 0}, - {1, 1350, 0, 5, 8, 0x0809090b, 0x0c0c0d0a, 0xff, 2, 0}, - {1, 1700, 0, 5, 8, 0x080a0a0c, 0x0c0d0e0a, 0xff, 2, 0}, - {1, 1900, 0, 4, 8, 0x080a0a0c, 0x0e0e0f0a, 0xff, 2, 0}, - {1, 2140, 0, 4, 8, 0x090a0b0c, 0x0e0f100b, 0xff, 2, 0}, - {} -}; - -/* - * The three slots have slightly different timing.
