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/common/board.c | 176 ++++++++++++++++++++++++++++++------------- 1 file changed, 125 insertions(+), 51 deletions(-) (limited to 'board/siemens/common') diff --git a/board/siemens/common/board.c b/board/siemens/common/board.c index fb2de48..c127f6c 100644 --- a/board/siemens/common/board.c +++ b/board/siemens/common/board.c @@ -75,8 +75,9 @@ int board_init(void) i2c_set_bus_num(0); if (read_eeprom() < 0) puts("Could not get board ID.\n"); - +#ifdef CONFIG_MACH_TYPE gd->bd->bi_arch_number = CONFIG_MACH_TYPE; +#endif gd->bd->bi_boot_params = CONFIG_SYS_SDRAM_BASE + 0x100; #ifdef CONFIG_FACTORYSET @@ -102,21 +103,29 @@ const struct dpll_params *get_dpll_ddr_params(void) } #ifndef CONFIG_SPL_BUILD + +#define MAX_NR_LEDS 10 +#define MAX_PIN_NUMBER 128 +#define STARTUP 0 + #if defined(BOARD_DFU_BUTTON_GPIO) -/* - * This command returns the status of the user button on - * Input - none - * Returns - 1 if button is held down - * 0 if button is not held down - */ -static int -do_userbutton(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) +unsigned char get_button_state(char * const envname, unsigned char def) { int button = 0; int gpio; + char *ptr_env; - gpio = BOARD_DFU_BUTTON_GPIO; - gpio_request(gpio, "DFU"); + /* If button is not found we take default */ + ptr_env = getenv(envname); + if (NULL == ptr_env) { + gpio = def; + } else { + gpio = (unsigned char)simple_strtoul(ptr_env, NULL, 0); + if (gpio > MAX_PIN_NUMBER) + gpio = def; + } + + gpio_request(gpio, ""); gpio_direction_input(gpio); if (gpio_get_value(gpio)) button = 1; @@ -127,53 +136,27 @@ do_userbutton(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) return button; } - -U_BOOT_CMD( - dfubutton, CONFIG_SYS_MAXARGS, 1, do_userbutton, - "Return the status of the DFU button", - "" -); -#endif -/* - * This command sets led - * Input - name of led - * value of led - * Returns - 1 if input does not match - * 0 if led was set +/** + * This command returns the status of the user button on + * Input - none + * Returns - 1 if button is held down + * 0 if button is not held down */ static int -do_setled(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) +do_userbutton(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) { - int gpio = 0; - if (argc != 3) - goto exit; -#if defined(BOARD_STATUS_LED) - if (!strcmp(argv[1], "stat")) - gpio = BOARD_STATUS_LED; -#endif -#if defined(BOARD_DFU_BUTTON_LED) - if (!strcmp(argv[1], "dfu")) - gpio = BOARD_DFU_BUTTON_LED; -#endif - /* If argument does not mach exit */ - if (gpio == 0) - goto exit; - gpio_request(gpio, ""); - gpio_direction_output(gpio, 1); - if (!strcmp(argv[2], "1")) - gpio_set_value(gpio, 1); - else - gpio_set_value(gpio, 0); - return 0; -exit: - return 1; + int button = 0; + button = get_button_state("button_dfu0", BOARD_DFU_BUTTON_GPIO); + button |= get_button_state("button_dfu1", BOARD_DFU_BUTTON_GPIO); + return button; } U_BOOT_CMD( - led, CONFIG_SYS_MAXARGS, 2, do_setled, - "Set led on or off", - "dfu val - set dfu led\nled stat val - set status led" + dfubutton, CONFIG_SYS_MAXARGS, 1, do_userbutton, + "Return the status of the DFU button", + "" ); +#endif static int do_usertestwdt(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) @@ -189,4 +172,95 @@ U_BOOT_CMD( "Sends U-Boot into infinite loop", "" ); + +/** + * Get led gpios from env and set them. + * The led define in environment need to need to be of the form ledN=NN,S0,S1 + * where N is an unsigned integer from 0 to 9 and S0 and S1 is 0 or 1.
