[U-Boot] [PATCH 0/9]EXYNOS5: Support for Exynos5250 Rev 1.0
by Rajeshwari Shinde 29 Jun '12

29 Jun '12

This patch set adds support for Exynos5250 Rev 1.0. Exynos5250 Rev 1.0 supports DDR3 Memory configuration and support for LPDDR2 is removed. Exynos5250 Rev 1.0 supports DWMMC driver but the support for same is not yet gone into Mainline. After DWMMC driver is added to Mainline support for generic S5P MMC driver will be removed. Due to Support of generic S5P MMC driver currently still being there in the Mainline you can see the following error on boot. mmc_reset: timeout error mmc_change_clock: timeout error mmc_send_cmd: waiting for status update MMC init failed Rajeshwari Shinde (9): ARCH: SPL: Add parametric board initializer SMDK5250: SPL: Define parametric board initializer SMDK5250: Add smdk5250-uboot-spl.lds EXYNOS5: CLOCK: define additional clock registers for Exynos5250 Rev 1.0 EXYNOS5: CLOCK: Add clock support for Exynos5250 Rev 1.0 Exynos5: DDR3: Adding the DDR3 memory setup for Exynos5250 Rev 1.0 EXYNOS5: CLOCK: Modify MPLL clock out for Exynos5250 Rev 1.0 EXYNOS5 : Modify pinnumx settings as per Exynos5250 Rev 1.0 SMDK5250: Enable UART and MMC for Exynos5250 Rev 1.0 arch/arm/cpu/armv7/exynos/clock.c | 12 +- arch/arm/cpu/armv7/exynos/pinmux.c | 18 +- arch/arm/include/asm/arch-exynos/clock.h | 37 +- arch/arm/include/asm/arch-exynos/dmc.h | 65 +++ arch/arm/include/asm/arch-exynos/spl.h | 95 +++ board/samsung/smdk5250/Makefile | 3 +- board/samsung/smdk5250/clock_init.c | 714 +++++++++++++++++++---- board/samsung/smdk5250/clock_init.h | 149 +++++ board/samsung/smdk5250/dmc_common.c | 199 +++++++ board/samsung/smdk5250/dmc_init.c | 462 --------------- board/samsung/smdk5250/dmc_init_ddr3.c | 228 ++++++++ board/samsung/smdk5250/setup.h | 765 +++++++++++++++---------- board/samsung/smdk5250/smdk5250-uboot-spl.lds | 66 +++ board/samsung/smdk5250/smdk5250.c | 6 +- board/samsung/smdk5250/smdk5250_spl.c | 68 +++ include/configs/smdk5250.h | 7 +- 16 files changed, 1968 insertions(+), 926 deletions(-) create mode 100644 arch/arm/include/asm/arch-exynos/spl.h create mode 100644 board/samsung/smdk5250/clock_init.h create mode 100644 board/samsung/smdk5250/dmc_common.c delete mode 100644 board/samsung/smdk5250/dmc_init.c create mode 100644 board/samsung/smdk5250/dmc_init_ddr3.c create mode 100644 board/samsung/smdk5250/smdk5250-uboot-spl.lds create mode 100644 board/samsung/smdk5250/smdk5250_spl.c -- 1.7.4.4

[U-Boot] NAND DMA timed out with i.mx boot source code.
by alex 29 Jun '12

29 Jun '12

Hi: I have one board which hardware copied from mx28evk board, and compiled the source code cloned from u-boot mainline git. The rom in mx28 print 0x80508008, that is "NAND DMA timed out". I compile the source from u-boot-testing, and it's no any wrong print, and the start is OK. I don't know why result in this issue. Best Regards, Alex

[U-Boot] [PATCH v2 0/1] fsl_elbc support for 4k devices and factory badblock migration
by Rafael Beims 28 Jun '12

28 Jun '12

This is my implementation of the factory badblock migration process for the fsl_elbc driver using the hack to support nand devices with page sizes bigger than 2048k. The migrated pattern is in "test mode". I really don't know what is the convention for something like this, and would like to hear suggestions of what this pattern should be. I would really appreciate any feedback related to the patch. Changes in v2: - Added check to disallow the migration code to run in devices with page size <= 2048 Rafael Beims (1): nand: Hack to support 4k page in fsl_elbc_nand drivers/mtd/nand/fsl_elbc_nand.c | 447 +++++++++++++++++++++++++++++++++++--- 1 files changed, 419 insertions(+), 28 deletions(-)

[U-Boot] [PATCH v4 0/9] feature additions and fixes for da850/omap-l138
by Prabhakar Lad 28 Jun '12

28 Jun '12

From: Lad, Prabhakar <prabhakar.lad(a)ti.com> This series adds MMC/SD, NAND and NOR SPL support for Logic PD's DA850/OMAP-L138 EVM. This series also fixes some issues found on the EVM during testing. The patches are sent in a series as these patches need to be applied in the order they are sent. The V2 version of patch series has been tested by Sughosh Ganu(urwithsughosh(a)gmail.com) and V3 version of the patch series has been tested by Christian Riesch (christian.riesch(a)omicron.at) for regression. Changes for v2: 1: Fixed comments from Tom to remove unused macro and add comment. 2: Fixed comments from Christian to move GPIO pins to board file and add a check to perform initializations only when CONFIG_SPL_LIBCOMMON_SUPPORT is defined. Changes for v3: 1: Fixed comments from Christian, to define CONFIG_SPL_MMC_LOAD config while booting from MMC. 2: Splitted patch 5(of v2), one for CONFIG_SPL_LIBCOMMON_SUPPORT check, one to define SPI specific configs of SP only when SPI flash is used and lastly to add NAND SPL support. 3: Rearranged the patch sequence. Changes for v4: 1: Fixed comment from Christian, to use clrbits_le32() which was wrongly using clrbits_be32().

[U-Boot] [RESEND Patch v3] Atmel : usb : add EHCI driver for Atmel SoC
by Bo Shen 28 Jun '12

28 Jun '12

Some Atmel SoC support USB EHCI, add the EHCI driver to support it. To enable the USB EHCI, add the following configuration options into board relative configuration file and remove USB OHCI options. #define CONFIG_USB_EHCI #define CONFIG_USB_EHCI_ATMEL #define CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS 2 Signed-off-by: Bo Shen <voice.shen(a)atmel.com> --- Change since v2: Add timeout and change the coding style Change since v1: Add WATCHDOG_RESET to avoid infinite loop. --- drivers/usb/host/Makefile | 1 + drivers/usb/host/ehci-atmel.c | 89 +++++++++++++++++++++++++++++++++++++++++ 2 files changed, 90 insertions(+) create mode 100644 drivers/usb/host/ehci-atmel.c diff --git a/drivers/usb/host/Makefile b/drivers/usb/host/Makefile index 59c3e57..4547f37 100644 --- a/drivers/usb/host/Makefile +++ b/drivers/usb/host/Makefile @@ -36,6 +36,7 @@ COBJS-$(CONFIG_USB_SL811HS) += sl811-hcd.o # echi COBJS-$(CONFIG_USB_EHCI) += ehci-hcd.o COBJS-$(CONFIG_USB_EHCI_ARMADA100) += ehci-armada100.o utmi-armada100.o +COBJS-$(CONFIG_USB_EHCI_ATMEL) += ehci-atmel.o ifdef CONFIG_MPC512X COBJS-$(CONFIG_USB_EHCI_FSL) += ehci-mpc512x.o else diff --git a/drivers/usb/host/ehci-atmel.c b/drivers/usb/host/ehci-atmel.c new file mode 100644 index 0000000..532db22 --- /dev/null +++ b/drivers/usb/host/ehci-atmel.c @@ -0,0 +1,89 @@ +/* + * (C) Copyright 2012 + * Atmel Semiconductor <www.atmel.com> + * Written-by: Bo Shen <voice.shen(a)atmel.com> + * + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
