From 61159b76844437bf9004c3a38b5a4ff1a24860d5 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Tue, 16 Jun 2015 14:59:34 +0200 Subject: arm, am33xx: update for siemens am335x based boards updates for the siemens am335x based boards: - draco: add delay for DDR3 configuration - change MTD partition layout and add a possibility to redefine MTD layout in board header. - move ubi support to common header file - draco: improve dtb naming - draco: set CONFIG_SYS_CBSIZE to 1024 - add generic env based led Leds can now be defined in Environment - add generic env based dfu button Which gpio is used for the dfu button can be defined through the Environment - set MACH_TYPE only if defined - draco: increase CPU freq to 300MHz - Add time command to siemens am33xx boards - DDR3: increase default tRFC - draco: enable pullup for DFU and ERST pin - change print format DDR3 Signed-off-by: Samuel Egli Acked-by: Heiko Schocher Reviewed-by: Tom Rini Signed-off-by: Heiko Schocher --- board/siemens/draco/board.c | 43 +++++++++++++++++++++++++++++++------------ 1 file changed, 31 insertions(+), 12 deletions(-) (limited to 'board/siemens/draco/board.c') diff --git a/board/siemens/draco/board.c b/board/siemens/draco/board.c index ede73baf3e..2697762076 100644 --- a/board/siemens/draco/board.c +++ b/board/siemens/draco/board.c @@ -43,7 +43,7 @@ static struct draco_baseboard_id __attribute__((section(".data"))) settings; /* Default@303MHz-i0 */ const struct ddr3_data ddr3_default = { 0x33524444, 0x56312e35, 0x0080, 0x0000, 0x003A, 0x003F, 0x009F, - 0x0079, 0x0888A39B, 0x26247FDA, 0x501F821F, 0x00100206, 0x61A44A32, + 0x0079, 0x0888A39B, 0x26517FDA, 0x501F84EF, 0x00100206, 0x61A44A32, 0x0000093B, 0x0000014A, "default name @303MHz \0", "default marking \0", @@ -71,8 +71,8 @@ static void print_ddr3_timings(void) printf("clock:\t\t%d MHz\n", DDR_PLL_FREQ); printf("device:\t\t%s\n", settings.ddr3.manu_name); printf("marking:\t%s\n", settings.ddr3.manu_marking); - printf("timing parameters\n"); - printf("diff\teeprom\tdefault\n"); + printf("%-20s, %-8s, %-8s, %-4s\n", "timing parameters", "eeprom", + "default", "diff"); PRINTARGS(magic); PRINTARGS(version); PRINTARGS(ddr3_sratio); @@ -96,9 +96,12 @@ static void print_ddr3_timings(void) static void print_chip_data(void) { + struct ctrl_dev *cdev = (struct ctrl_dev *)CTRL_DEVICE_BASE; + dpll_mpu_opp100.m = am335x_get_efuse_mpu_max_freq(cdev); printf("\nCPU BOARD\n"); printf("device: \t'%s'\n", settings.chip.sdevname); printf("hw version: \t'%s'\n", settings.chip.shwver); + printf("max freq: \t%d MHz\n", dpll_mpu_opp100.m); } #endif /* CONFIG_SPL_BUILD */ @@ -193,6 +196,11 @@ struct ctrl_ioregs draco_ddr3_ioregs = { config_ddr(DDR_PLL_FREQ, &draco_ddr3_ioregs, &draco_ddr3_data, &draco_ddr3_cmd_ctrl_data, &draco_ddr3_emif_reg_data, 0); + + /* For Samsung 2Gbit RAM we need this delay otherwise config fails after + * soft reset. + */ + udelay(2000); } static void spl_siemens_board_init(void) @@ -201,6 +209,26 @@ static void spl_siemens_board_init(void) } #endif /* if def CONFIG_SPL_BUILD */ +#ifdef CONFIG_BOARD_LATE_INIT +int board_late_init(void) +{ + omap_nand_switch_ecc(1, 8); +#ifdef CONFIG_FACTORYSET + /* Set ASN in environment*/ + if (factory_dat.asn[0] != 0) { + setenv("dtb_name", (char *)factory_dat.asn); + } else { + /* dtb suffix gets added in load script */ + setenv("dtb_name", "am335x-draco"); + } +#else + setenv("dtb_name", "am335x-draco"); +#endif + + return 0; +} +#endif + #if (defined(CONFIG_DRIVER_TI_CPSW) && !defined(CONFIG_SPL_BUILD)) || \ (defined(CONFIG_SPL_ETH_SUPPORT) && defined(CONFIG_SPL_BUILD)) static void cpsw_control(int enabled) @@ -280,13 +308,4 @@ U_BOOT_CMD( #endif /* #if defined(CONFIG_DRIVER_TI_CPSW) */ #endif /* #if (defined(CONFIG_DRIVER_TI_CPSW) && !defined(CONFIG_SPL_BUILD)) */ -#ifdef CONFIG_BOARD_LATE_INIT -int board_late_init(void) -{ - omap_nand_switch_ecc(1, 8); - - return 0; -} -#endif - #include "../common/board.c" -- cgit
