[U-Boot] [U-boot] usbslave command
by TigerLiu＠viatech.com.cn 17 Feb '13

17 Feb '13

Hi,experts: I have a question about using usb port to download files to memory. Some ARM OEM vendors have released customed uboot with integrated usbslave command. Developers could download files to target board's dram through USB port. So, official uboot release version has plans to integrate this function? Best wishes,

[U-Boot] [PATCH v2 0/10] mx23/mxs pending patches
by Otavio Salvador 16 Feb '13

16 Feb '13

This patchset includes the pending patches we have in our tree. It fixes issues for mx23evk and mx23_olinuxino boards. The DRAM control register change has been kept specific to mx23evk as it breaks mx23_olinuxino (as it than reads only 16MB) Changes in v2: - Extend code comment to explicit say it needs to be there. - Use MUX pin name - Requested by Marek - Avoid wrong clock setting in MX23 - Add changes for allow use of the USB hub - Remove extra newline Otavio Salvador (10): mxs: Rename CONFIG_SPL_MX28_PSWITCH_WAIT to CONFIG_SPL_MXS_PSWITCH_WAIT mx23: Document the tRAS lockout setting in memory initialization mx23evk: Adjust DRAM control register to use full 128MB of RAM led: Use STATUS_LED_ON and STATUS_LED_OFF when calling __led_set mxs: Fix iomux.h to not break build during assembly stage mx23_olinuxino: Add support for status LED usb: mxs: Disable USB Port 1 for i.MX23 mx23evk: Enable USB support mx23_olinuxino: Enable USB support mx23_olinuxino: Add ethernet support arch/arm/cpu/arm926ejs/mxs/mxs_init.h | 2 +- arch/arm/cpu/arm926ejs/mxs/spl_mem_init.c | 1 + arch/arm/cpu/arm926ejs/mxs/spl_power_init.c | 2 +- arch/arm/include/asm/arch-mxs/iomux.h | 5 +++ board/freescale/mx23evk/spl_boot.c | 10 +++++ board/olimex/mx23_olinuxino/mx23_olinuxino.c | 13 ++++++ board/olimex/mx23_olinuxino/spl_boot.c | 8 ++++ common/cmd_led.c | 6 ++- drivers/usb/host/ehci-mxs.c | 12 ++++++ include/configs/mx23_olinuxino.h | 63 ++++++++++++++++++++++++++-- include/configs/mx23evk.h | 10 +++++ 11 files changed, 125 insertions(+), 7 deletions(-) -- 1.8.1

[U-Boot] [PATCH V6 00/10] EXYNOS5: Enable DWMMC, add FDT support for DWMMC and enable EMMC boot
by Amar 16 Feb '13

16 Feb '13

This patch set enables and initialises DWMMC for Exynos5250 on SMDK5250. Adds driver changes required for DWMMC. Adds FDT support for DWMMC. Adds EMMC boot support for SMDK5250. This patch set is based on: "EXYNOS: mmc: support DesignWare Controller for Samsung-SoC", which is merged in u-boot-mmc. "Exynos: clock: support get_mmc_clk for exynos". "Add DT based ethernet driver for SMDK5250". "SMDK5250: Add FDT support" present at the following link http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/149991 Changes from V1: 1)Corrected in response to review comments. 2)Created separate board files for FDT and non-FDT versions. 3)Added binding file for DWMMC device node. 4)Removed the propname 'index' from device node. 5)Prefixed the vendor name 'samsung' before propname in device node. 6)Ensured to have same signature for the function exynos_dwmci_init() for both FDT and non-FDT versions. 7)EMMC clock setting has been moved from spl_boot.c to clock_init.c. Changes from V2: 1)Updation of commit message and resubmition of proper patch set. Changes from V3: 1)Updated to use the macro DWMCI_CTRL_SEND_AS_CCSD instead of the hard coded value (1 << 10). 2)In the file exynos_dw_mmc.c, replaced the new function exynos5_mmc_set_clk_div() with the existing function set_mmc_clk(). set_mmc_clk() will do the purpose. 3)In the file exynos_dw_mmc.c, computation of FSYS block clock divisor (pre-ratio) value is added. 4)Removed the new function exynos5_mmc_set_clk_div() from clock.c. Changes from V4: 1)Updated the function dwmci_send_cmd() to use get_timer() instead of using mdelay(1). 2)Replaced the function call 'exynos_dwmmc_init(0, 8);' with the function exynos_dwmmc_add_port() in smdk5250.c. 3)The function get_irom_func(int index) has been added to avoid type casting at many places. 4)Used the generic function "mmc_boot_part_access()" instead of two functions "mmc_boot_open()" and "mmc_boot_close()". By doing so user can specify which boot partition to be accessed (opened / closed). Changes from V5: 1)Added the 'removable' flag to mmc device node. 2)Changed the mmc clock value from 50MHz to 52MHz in the function exynos_dwmci_add_port() present in file drivers/mmc/exynos_dw_mmc.c. 3)Enabled CONFIG_LCD only for non-FDT operation. 4)Removed the function call i2c_init() present inside the function board_i2c_init().
