[U-Boot] [PATCH 0/6] Addition of new board Peach-Pi
by Akshay Saraswat 10 Oct '14

10 Oct '14

Now we are adding a new Peach-Pi board which is a variant of Peach-Pit and is based on Exynos5800. Exynos5800 itself is a variant of Exynos5420, hence, most of the hardware config and settings are reused for this board.

[U-Boot] [PATCH v2] arm: pxa: use common timer functions
by Andrew Ruder 10 Oct '14

10 Oct '14

This patch moves pxa to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) pxa timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locked the processor. Rather than patch the specific pxa issues, simply move everything over to the common code. Signed-off-by: Andrew Ruder <andrew.ruder(a)elecsyscorp.com> Cc: Marek Vasut <marex(a)denx.de> Cc: Tom Rini <trini(a)ti.com> --- FIRST VERSION AVAILABLE AT: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/192978 I missed some compile-testing last time and didn't notice that not every board includes configs/pxa-common.h. Rather than try to fix-up every board config (and possibly break out of tree ones, etc.), add a PXA-specific config.h. In any case, it must be something included via common.h as the generic time framework requires the CONFIG_SYS_TIMER_COUNTER definition. One potential gotcha here is that now pxa-regs gets included via common.h which adds lots of short register names to the global namespace. Compile-tested every PXA board from the generated boards.cfg and didn't see any issues. Board-tested the PXA270. checkpatch output: total: 0 errors, 0 warnings, 0 checks, 75 lines checked NOTE: Ignored message types: COMPLEX_MACRO CONSIDER_KSTRTO MINMAX MULTISTATEMENT_MACRO_USE_DO_WHILE NETWORKING_BLOCK_COMMENT_STYLE USLEEP_RANGE 0001-arm-pxa-use-common-timer-functions.patch has no obvious style problems and is ready for submission. arch/arm/cpu/pxa/timer.c | 69 +--------------------------------- arch/arm/include/asm/arch-pxa/config.h | 25 ++++++++++++ arch/arm/include/asm/config.h | 5 ++- 3 files changed, 30 insertions(+), 69 deletions(-) create mode 100644 arch/arm/include/asm/arch-pxa/config.h diff --git a/arch/arm/cpu/pxa/timer.c b/arch/arm/cpu/pxa/timer.c index c4717de..11fefd5 100644 --- a/arch/arm/cpu/pxa/timer.c +++ b/arch/arm/cpu/pxa/timer.c @@ -6,80 +6,13 @@ * SPDX-License-Identifier: GPL-2.0+ */ -#include <asm/arch/pxa-regs.h> #include <asm/io.h> #include <common.h> -#include <div64.h> DECLARE_GLOBAL_DATA_PTR; -#define TIMER_LOAD_VAL 0xffffffff - -#define timestamp (gd->arch.tbl) -#define lastinc (gd->arch.lastinc) - -#if defined(CONFIG_CPU_PXA27X) || defined(CONFIG_CPU_MONAHANS) -#define TIMER_FREQ_HZ 3250000 -#elif defined(CONFIG_CPU_PXA25X) -#define TIMER_FREQ_HZ 3686400 -#else -#error "Timer frequency unknown - please config PXA CPU type" -#endif - -static unsigned long long tick_to_time(unsigned long long tick) -{ - return lldiv(tick * CONFIG_SYS_HZ, TIMER_FREQ_HZ); -} - -static unsigned long long us_to_tick(unsigned long long us) -{ - return lldiv(us * TIMER_FREQ_HZ, 1000000); -} - int timer_init(void) { - writel(0, OSCR); + writel(0, CONFIG_SYS_TIMER_COUNTER); return 0; } - -unsigned long long get_ticks(void) -{ - /* Current tick value */ - uint32_t now = readl(OSCR); - - if (now >= lastinc) { - /* - * Normal mode (non roll) - * Move stamp forward with absolute diff ticks - */ - timestamp += (now - lastinc); - } else { - /* We have rollover of incrementer */ - timestamp += (TIMER_LOAD_VAL - lastinc) + now; - } - - lastinc = now; - return timestamp; -} - -ulong get_timer(ulong base) -{ - return tick_to_time(get_ticks()) - base; -} - -void __udelay(unsigned long usec) -{ - unsigned long long tmp; - ulong tmo; - - tmo = us_to_tick(usec); - tmp = get_ticks() + tmo; /* get current timestamp */ - - while (get_ticks() < tmp) /* loop till event */ - /*NOP*/; -} - -ulong get_tbclk(void) -{ - return TIMER_FREQ_HZ; -} diff --git a/arch/arm/include/asm/arch-pxa/config.h b/arch/arm/include/asm/arch-pxa/config.h new file mode 100644 index 0000000..5836945 --- /dev/null +++ b/arch/arm/include/asm/arch-pxa/config.h @@ -0,0 +1,25 @@ +/* + * Copyright (C) 2014 Andrew Ruder <andrew.ruder(a)elecsyscorp.com> + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#ifndef _ASM_ARM_PXA_CONFIG_ +#define _ASM_ARM_PXA_CONFIG_ + +#include <asm/arch/pxa-regs.h> + +/* + * Generic timer support + */ +#if defined(CONFIG_CPU_PXA27X) || defined(CONFIG_CPU_MONAHANS) +#define CONFIG_SYS_TIMER_RATE 3250000 +#elif defined(CONFIG_CPU_PXA25X) +#define CONFIG_SYS_TIMER_RATE 3686400 +#else +#error "Timer frequency unknown - please config PXA CPU type" +#endif + +#define CONFIG_SYS_TIMER_COUNTER OSCR + +#endif /* _ASM_ARM_PXA_CONFIG_ */ diff --git a/arch/arm/include/asm/config.h b/arch/arm/include/asm/config.h index be80434..1cfc83b 100644 --- a/arch/arm/include/asm/config.h +++ b/arch/arm/include/asm/config.h @@ -23,7 +23,10 @@ #include <asm/arch-fsl-lsch3/config.h> #endif -#ifdef CONFIG_LS102XA +#if defined(CONFIG_LS102XA) || \ + defined(CONFIG_CPU_PXA27X) || \ + defined(CONFIG_CPU_MONAHANS) || \ + defined(CONFIG_CPU_PXA25X) #include <asm/arch/config.h> #endif -- 2.1.1

[U-Boot] SUNXI NAND CONTROLLER Driver Model (WIP)
by Yassin Jaffer 10 Oct '14

10 Oct '14

Hi I'm developing a u-boot driver for the sunxi nand controller https://github.com/yassinjaffer/u-boot <https://github.com/yassinjaffer/u-boot/tree/sunxi-nand/doc/driver-model>. My work is based on bbrezillon mainline driver https://github.com/bbrezillon/linux-sunxi. I would like to move the driver to use the DM framework so I'm wondering if someone could kindly give some suggestions on how to accomplish this. I do know that DM is still WIP but I believe that the nand driver can take advantage of the DM since I'm using the FDT for the run-time configuration. Thank you in advance. Yassin Jaffer
