As sayed before I'd like to switch the 'ATMEL_LEGACY' PIO API to be the new one. Would it be Ok for you to wait a few days for me to prepare the API for all pio features to be able to feed with a single pin input? Beside that I said to provide some PIO API with PORT + MASK input. I still think that would be useful but I do not plan to work on that for this release. I'd be happy if you could do that, but changing it later is also Ok for me. > + > + /* > + * Need to reset PHY ?-> 200us reset > + * Bug within Atmel CPU (undefined initial states on io-lines)! > + * Startup Ethernet Switch delayed so that hardstrap(Switch Config) > + * has defined state after cold start (do not break daisy chain!). > + */ > + if ((readl(&rstc->sr) & AT91_RSTC_RSTTYP) == AT91_RSTC_RSTTYP_GENERAL) > + at91_set_gpio_output(AT91_PIN_PA25, 0); > + > + One empty line could be left out. > + erstl = readl(&rstc->mr) & AT91_RSTC_MR_ERSTL_MASK; > + > + /* Need to reset PHY -> 500ms reset */ > + writel(AT91_RSTC_KEY | AT91_RSTC_MR_ERSTL(13) | > + AT91_RSTC_MR_URSTEN, &rstc->mr); > + > + writel(AT91_RSTC_KEY | AT91_RSTC_CR_EXTRST, &rstc->cr); > + > + /* Wait for end of reset */ > + at91_wait_for_reset(100); > + > + /* Restore NRST value */ > + writel(AT91_RSTC_KEY | erstl | AT91_RSTC_MR_URSTEN, &rstc->mr); > + > + at91_set_gpio_input(AT91_PIN_PA25, 1); /* ERST tri-state */ > + > + /* Re-enable pull-up */ > + at91_set_pio_pullup(AT91_PIO_PORTA, 14, 1); > + at91_set_pio_pullup(AT91_PIO_PORTA, 15, 1); > + at91_set_pio_pullup(AT91_PIO_PORTA, 17, 1); > + at91_set_pio_pullup(AT91_PIO_PORTA, 25, 1); > + at91_set_pio_pullup(AT91_PIO_PORTA, 26, 1); > + at91_set_pio_pullup(AT91_PIO_PORTA, 28, 1); > + > + /* Initialize EMAC=MACB hardware */ > + at91_macb_hw_init(); > +} > +#endif > + > +#ifdef CONFIG_GENERIC_ATMEL_MCI > +int board_mmc_init(bd_t *bd) > +{ > + at91_mci_hw_init(); > + > + return atmel_mci_init((void *)ATMEL_BASE_MCI); > +} > +#endif > + > +int board_early_init_f(void) > +{ > + struct at91_pmc *pmc = (struct at91_pmc *)ATMEL_BASE_PMC; > + > + /* Enable clocks for all PIOs */ > + writel((1 << ATMEL_ID_PIOA) | (1 << ATMEL_ID_PIOB) | > + (1 << ATMEL_ID_PIOC), > + &pmc->pcer); > + > + return 0; > +} > + > +int board_init(void) > +{ > + /* adress of boot parameters */ > + gd->bd->bi_boot_params = CONFIG_SYS_SDRAM_BASE + 0x100; > + > + at91_seriald_hw_init(); I think enabling debug output in early_init is more useful than here. > +#ifdef CONFIG_CMD_NAND > + taurus_nand_hw_init(); > +#endif > +#ifdef CONFIG_MACB > + taurus_macb_hw_init(); > +#endif > + > + return 0; > +} > + > +int dram_init(void) > +{ > + gd->ram_size = get_ram_size((void *)CONFIG_SYS_SDRAM_BASE, > + CONFIG_SYS_SDRAM_SIZE); > + return 0; > +} > + > +int board_eth_init(bd_t *bis) > +{ > + int rc = 0; > +#ifdef CONFIG_MACB > + rc = macb_eth_initialize(0, (void *)ATMEL_BASE_EMAC0, 0x00); > +#endif > + return rc; > +} > diff --git a/boards.cfg b/boards.cfg > index aa2ee64..0fe98d0 100644 > --- a/boards.cfg > +++ b/boards.cfg > @@ -139,6 +139,8 @@ Active arm arm926ejs at91 ronetix pm9263 > Active arm arm926ejs at91 ronetix pm9g45 pm9g45 pm9g45:AT91SAM9G45 Ilko Iliev <iliev@ronetix.at> > Active arm arm926ejs at91 taskit stamp9g20 portuxg20 stamp9g20:AT91SAM9G20,PORTUXG20 Markus Hubig <mhubig@imko.de> > Active arm arm926ejs at91 taskit stamp9g20 stamp9g20 stamp9g20:AT91SAM9G20 Markus Hubig <mhubig@imko.de> > +Active arm arm926ejs at91 siemens taurus axm taurus:AT91SAM9G20,MACH_TYPE=2068,BOARD_AXM Heiko Schocher <hs@denx.de> > +Active arm arm926ejs at91 siemens taurus taurus taurus:AT91SAM9G20,MACH_TYPE=2067,BOARD_TAURUS Heiko Schocher <hs@denx.de> > Active arm arm926ejs davinci ait cam_enc_4xx cam_enc_4xx cam_enc_4xx Heiko Schocher <hs@denx.de> > Active arm arm926ejs davinci Barix ipam390 ipam390 - Heiko Schocher <hs@denx.de> > Active arm arm926ejs davinci davinci da8xxevm da830evm - Nick Thompson <nick.thompson@gefanuc.com> > diff --git a/include/configs/taurus.h b/include/configs/taurus.h > new file mode 100644 > index 0000000..26255bb > --- /dev/null > +++ b/include/configs/taurus.h > @@ -0,0 +1,159 @@ > +/* > + * Common board functions for Siemens TAURUS (AT91SAM9G20) based boards > + * (C) Copyright 2013 Siemens AG > + * > + * Based on: > + * U-Boot file: include/configs/at91sam9260ek.h > + * > + * (C) Copyright 2007-2008 > + * Stelian Pop <stelian@popies.net> > + * Lead Tech Design <www.leadtechdesign.com> > + * > + * SPDX-License-Identifier: GPL-2.0+ > + */ > + > +#ifndef __CONFIG_H > +#define __CONFIG_H > + > +/* > + * SoC must be defined first, before hardware.h is included. > + * In this case SoC is defined in boards.cfg. > + */ > +#include <asm/hardware.h> > + > +#define MACH_TYPE_TAURUS 2067 > +#define MACH_TYPE_AXM 2068 > + > +/* > + * Warning: changing CONFIG_SYS_TEXT_BASE requires > + * adapting the initial boot program. > + * Since the linker has to swallow that define, we must use a pure > + * hex number here!

If I see this correct, > only the pin setup is board specific, or? That's true. How could we provide the gpio setup to a common function then? I think we should go with some at91_phy_reset() which should preferably run before enabling the (e)macb (would that be true for CONFIG_RESET_PHY_R?). I haven't checked it but think it would be Ok to enable the (e)macb peripheral clock when enabling the peripheral. Therefore the 'Enable EMAC clock' above could be removed. _All_ at91_macb_hw_init() should therefore enable the peripheral clock ... unfortunately some do not at the moment. <snip> >>> +/* USB */ >>> +#if defined(CONFIG_BOARD_TAURUS) >>> +#define CONFIG_USB_ATMEL >>> +#define CONFIG_USB_OHCI_NEW >>> +#define CONFIG_SYS_USB_OHCI_CPU_INIT >>> +#define CONFIG_SYS_USB_OHCI_REGS_BASE 0x00500000 >>> +#define CONFIG_SYS_USB_OHCI_SLOT_NAME "at91sam9260" >>> +#define CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS 2LEGA >> >> What does '2LEGA' mean here? > > Hups...

Yea, maybe some cursor jump around in MUA while writing 'ATMEL_LEGACY'. Sorry for the trouble. Best regards Andreas Bießmann
