You can always read SoC info values directly from the hardware registers if you need them. There is no value in caching those infos in global_data. Yes, these values ware write in function "print_cpuinfo", then u-boot run at ROM space, have no writable memory. Their can't be acquired directly by read register, need code to make judgments. > diff --git a/arch/mips/mach-ath79/ar933x/board.c b/arch/mips/mach-ath79/ar933x/board.c > new file mode 100644 > index 0000000..b4a76e8 > --- /dev/null > +++ b/arch/mips/mach-ath79/ar933x/board.c > @@ -0,0 +1,42 @@ > +/* > + * (C) Copyright 2015 > + * Wills Wang, <wills.wang@live.com> > + * > + * SPDX-License-Identifier: GPL-2.0+ > + */ > + > +#include <common.h> > +#include <asm/io.h> > +#include <asm/addrspace.h> > +#include <asm/types.h> > +#include <mach/ar71xx_regs.h> > +#include <mach/ddr.h> > + > +DECLARE_GLOBAL_DATA_PTR; > + > +static void uart_pin_init(void) > +{ > + u32 val; > + > + /* > + * Set GPIO10 (UART_SO) as output and enable UART, > + * BIT(15) in GPIO_FUNCTION_1 register must be written with 1 > + */ > + val = readl(KSEG1ADDR(AR71XX_GPIO_BASE + AR71XX_GPIO_REG_OE)); > + val |= BIT(10); > + writel(val, KSEG1ADDR(AR71XX_GPIO_BASE + AR71XX_GPIO_REG_OE)); > + > + val = readl(KSEG1ADDR(AR71XX_GPIO_BASE + AR71XX_GPIO_REG_FUNC)); > + val |= (AR933X_GPIO_FUNC_UART_EN | BIT(15)); > + writel(val, KSEG1ADDR(AR71XX_GPIO_BASE + AR71XX_GPIO_REG_FUNC)); > +} > + > + > +#ifdef CONFIG_BOARD_EARLY_INIT_F > +int board_early_init_f(void) > +{ > + uart_pin_init(); > + ddr_init(); > + return 0; > +} > +#endif > the content of this file should be moved to your board directory. As Marek already mentioned, PIN setup is board-specific. Probably not all AR933x based boards need to setup that UART pin. For ar933x, all board need to call ddr_init, or board don't boot up. ar933x have only one UART, we can't see any printout if uart_pin_init is missed. >> diff --git a/arch/mips/mach-ath79/ar933x/clk.c b/arch/mips/mach-ath79/ar933x/clk.c >> new file mode 100644 >> index 0000000..cfc4bb9 >> --- /dev/null >> +++ b/arch/mips/mach-ath79/ar933x/clk.c >> @@ -0,0 +1,86 @@ >> +/* >> + * (C) Copyright 2015 >> + * Wills Wang, <wills.wang@live.com> >> + * >> + * SPDX-License-Identifier: GPL-2.0+ >> + */ >> + >> +#include <common.h> >> +#include <asm/io.h> >> +#include <asm/addrspace.h> >> +#include <asm/types.h> >> +#include <mach/ar71xx_regs.h> >> + >> +DECLARE_GLOBAL_DATA_PTR; >> + >> +static u32 ar933x_get_xtal(void) >> +{ >> + u32 val; >> + >> + val = readl(KSEG1ADDR(AR71XX_RESET_BASE + AR933X_RESET_REG_BOOTSTRAP)); > now that you have implemented map_phymem(), you should always use it. > > const void __iomem *regs = map_physmem(AR71XX_RESET_BASE, AR71XX_RESET_SIZE, MAP_NOCACHE); > ... > val = readl(regs + AR933X_RESET_REG_BOOTSTRAP); > > > I'm going to sync asm/io.h and others with the kernel.

Now I have clearer picture of this device. In serial flash mode, it reads like CFI flash. But we need to switch to bitbanging mode to write flash. In bitbanging, we have shift in data as word read. Though the cs, clk and dout are gpio. And the soft-spi of u-boot won't fit well. So the current ath79_spi_delay() is fine. as we don't have ndelay() in u-boot yet. But the set_speed() code is for serial flash mode, and does not apply to bitbanging mode. You should save the result of do_div(tick, max_hz) to priv data, because dividing can take some time. You may trim the count with rrw_delay like that of Linux driver for more accurate timing. BTW, the usage of uint8_t,uint32_t and uint64_t is deprecated. Please change them to u8, u32 and u64. It will be helpful to run checkpatch.pl. Thanks a lot for your work. Best regards, Thomas ^ permalink raw reply [flat|nested] 24+ messages in thread

Next, in openwrt tree there is a dirty-hacky ath79-spi linux kernel patch for very impressive SPI flash read speedup (2 MiB/s instead of 20 KiB/s, I have no precise bandwidth results at the moment). So for better performance it is reasonable to have separate ath79-spi driver. --? Best regards, ? Antony Pavlov ^ permalink raw reply [flat|nested] 24+ messages in thread
