Using IS_ENABLED for configuring smc->mode is an optimization, reduce init.o text from 905 to 877. Signed-off-by: Fabio Porcedda Cc: Jean-Christophe PLAGNIOL-VILLARD --- v3: - fix second patch using IS_ENABLED to discard the struct. - squash them because both use IS_ENABLED in the same way. v2: - fixed the first patch by removing the #ifdef inside nand_pdata definition. arch/arm/boards/at91sam9260ek/init.c | 31 +++++++++++++------------------ 1 file changed, 13 insertions(+), 18 deletions(-) diff --git a/arch/arm/boards/at91sam9260ek/init.c b/arch/arm/boards/at91sam9260ek/init.c index 06a53f2..77ca6bb 100644 --- a/arch/arm/boards/at91sam9260ek/init.c +++ b/arch/arm/boards/at91sam9260ek/init.c @@ -37,9 +37,8 @@ static void ek_set_board_type(void) { if (machine_is_at91sam9g20ek()) { armlinux_set_architecture(MACH_TYPE_AT91SAM9G20EK); -#ifdef CONFIG_AT91_HAVE_2MMC - armlinux_set_revision(HAVE_2MMC); -#endif + if (IS_ENABLED(CONFIG_AT91_HAVE_2MMC)) + armlinux_set_revision(HAVE_2MMC); } else { armlinux_set_architecture(MACH_TYPE_AT91SAM9260EK); } @@ -51,11 +50,6 @@ static struct atmel_nand_data nand_pdata = { .det_pin = -EINVAL, .rdy_pin = AT91_PIN_PC13, .enable_pin = AT91_PIN_PC14, -#if defined(CONFIG_MTD_NAND_ATMEL_BUSWIDTH_16) - .bus_width_16 = 1, -#else - .bus_width_16 = 0, -#endif .on_flash_bbt = 1, }; @@ -107,10 +101,12 @@ static void ek_add_device_nand(void) smc = &ek_9260_nand_smc_config; /* setup bus-width (8 or 16) */ - if (nand_pdata.bus_width_16) + if (IS_ENABLED(CONFIG_MTD_NAND_ATMEL_BUSWIDTH_16)) { + nand_pdata.bus_width_16 = 1; smc->mode |= AT91_SMC_DBW_16; - else + } else { smc->mode |= AT91_SMC_DBW_8; + } /* configure chip-select 3 (NAND) */ sam9_smc_configure(0, 3, smc); @@ -157,7 +153,6 @@ static void at91sam9260ek_phy_reset(void) /* * MCI (SD/MMC) */ -#if defined(CONFIG_MCI_ATMEL) static struct atmel_mci_platform_data __initdata ek_mci_data = { .bus_width = 4, .slot_b = 1, @@ -165,14 +160,14 @@ static struct atmel_mci_platform_data __initdata ek_mci_data = { static void ek_usb_add_device_mci(void) { + if (!IS_ENABLED(CONFIG_MCI_ATMEL)) + return; + if (machine_is_at91sam9g20ek()) ek_mci_data.detect_pin = AT91_PIN_PC9; at91_add_device_mci(0, &ek_mci_data); } -#else -static void ek_usb_add_device_mci(void) {} -#endif /* * USB Host port @@ -209,10 +204,10 @@ static void __init ek_add_led(void) { int i; -#ifdef CONFIG_AT91_HAVE_2MMC - leds[0].gpio = AT91_PIN_PB8; - leds[1].gpio = AT91_PIN_PB9; -#endif + if (IS_ENABLED(CONFIG_AT91_HAVE_2MMC)) { + leds[0].gpio = AT91_PIN_PB8; + leds[1].gpio = AT91_PIN_PB9; + } for (i = 0; i < ARRAY_SIZE(leds); i++) { at91_set_gpio_output(leds[i].gpio, leds[i].active_low); -- 1.8.1.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
