[U-Boot] [PATCH 1/2] easylogo: add lzma support
by Mike Frysinger 19 Jun '12

19 Jun '12

Compressing the logos with lzma rather than gzip saves ~9kb with the Blackfin 24bit images and ~3kb with the 16bit images. Add a new -l option to easylogo so people can pick lzma as their decompression routine.

[U-Boot] [PATCH 0/6] further updates for keymile powerpc 83xx boards
by Holger Brunck 19 Jun '12

19 Jun '12

This patchserie provides further updates for km ppc 83xx boards. One serie is already posted but until now not committed. This patch serie therefore is made on top of the first serie: http://lists.denx.de/pipermail/u-boot/2012-March/120694.html Beside some enhancements for kmcoge5ne, there are two common features for keymile boards changed. This is the change in the bootlimit and the addition of the check of the SW in a test_bank. Only km code is changed, there is no change in common u-boot code. Holger Brunck (1): km/common: increase bootlimit to 3 Stefan Bigler (1): powerpc/83xx/km: added missing enable of application buffer Thomas Herzmann (4): km/common: fixed error in ethaddr (1-byte-shift) powerpc/83xx: configure CONFIG_POST for kmcoge5ne powerpc/83xx/km: readout dip_switch on kmcoge5ne km/common: check test_bank and testpin for testboot board/keymile/common/common.c | 36 +++++++++++++++++++++++++ board/keymile/common/common.h | 8 +++++- board/keymile/common/ivm.c | 2 +- board/keymile/km83xx/km83xx.c | 50 +++++++++++++++++++++++++++++++++++ include/configs/km/keymile-common.h | 6 +++- include/configs/km8360.h | 8 +++++ 6 files changed, 106 insertions(+), 4 deletions(-)

[U-Boot] splash screen on uboot 1.3.4
by Gigin Jose 19 Jun '12

19 Jun '12

Hi, I am working on s3c2416 ARM9 based processor. The u-boot version used is u-boot 1.3.4. This u-boot does not have the splash screen implemented on the source code. To enable the splash screen, I defined CONFIG_SPLASH_SCREEN in include/configs/smdk2416.h file. Now I get the error "undefined reference to `video_display_bitmap'". So, the frame buffer driver was not initialized in my bootloader. I have the reference code for LCD initialization in the kernel driver, so I thought of implementing a similar initialization on the bootloader also. I am confused, from where to start the initialization for the LCD in the bootloader. Should I start writing the driver from scratch, or is there any reference code from I can start of for the LCD initialization. Should I add one more initialization sequence inside *init_sequence[] array in the start_armboot function, or can I make use of the drv_lcd_init inside common/lcd.c file. what would be a better approach to start with ? Thank You With Regards GIGIN JOSE

[U-Boot] u-boot on c6x CPU ( texas instruments c6000 )

Can i share patches for start u-boot on tms320c6745 processor (http://www.ti.com/product/tms320c6745)? What is the best way? May be somebody already make support c6000 (c6x) arch in u-boot? For information: C6X family of processors supported by gcc from version 4.7.0. C6745 pin compatible with AM1705 (http://www.ti.com/product/am1705), only CPU core is different, because drivers for davinci work ok on c6745. I'm work on this SOM http://inmys.ru/?_=/products/som_c6745 Now work: uart, nand, ethernet (drivers/serial/ns16550.c, drivers/mtd/nand/davinci_nand.c, drivers/net/davinci_emac.c)

[U-Boot] [PATCH] ARM: support for cache coherent allocations
by Ilya Yanok 19 Jun '12

19 Jun '12

This is a draft implementation of cache coherent memory allocator. This simple implementation just reserves memory area below malloc space and leave it uncached even if data cache is enabled. Allocations are even simpler: code just verifies that we have enough space and increments the offset counter. No deallocations supported for now. In future versions we could probably use dlmalloc allocator to get space out of coherent pool.

[U-Boot] USB DFU support into mailline.
by Sohanpal, Harman 19 Jun '12

19 Jun '12

Hi, Referring to http://elinux.org/Merge_DFU_support_into_mainline_U-Boot, it seems some work is going on for adding USB DFU support in the mainline for u-boot. But I could not find any code already in mainline. Is there anyone working on getting USB DFU support to mainline? I am working on USB DFU on AM335x BeagleBone, and I want help get USB DFU to mainline. Thanks, Harman

[U-Boot] [PATCH 0/8 V2] EXYNOS5: Enable I2C support
by Rajeshwari Shinde 19 Jun '12

19 Jun '12

This patch set enables I2C support for EXYNOS5. This patchset modifies the s3c24x0 I2C driver to use same for EXYNOS5. Multichannel support has been added to the s3c24x0 I2C driver. s3c24x0_i2c struct has been moved to a common place as it can used by different SOC's. Changes in V2: - Incorporated review comments from Simon Glass. - Aligned the pinmux functionality as per latest comments. This patchset depends on the following patch: "[U-Boot] [PATCH 1/2 V6] EXYNOS5: PINMUX: Added default pinumx settings" Rajeshwari Shinde (8): EXYNOS: CLK: Add i2c clock EXYNOS: Add I2C base address.
