[U-Boot] [PATCH v2 0/2] video: dw_hdmi: fix HSYNC and VSYNC polarity settings
by Vasily Khoruzhick 15 May '18

15 May '18

Previous attempt to fix HSYNC and VSYNC polarity settings for dw_hdmi on sunxi wasn't completely correct - there's another bug in dw_hdmi driver. This series fixes hsync/vsync settings in sunxi glue driver and applies proper fix to dw_hdmi v2: don't revert earlier fix, just use correct bits for hsync and vsync Vasily Khoruzhick (2): sunxi: video: HDMI: use correct bits for HSYNC and VSYNC polarity. video: dw_hdmi: fix HSYNC and VSYNC polarity settings drivers/video/dw_hdmi.c | 4 ++-- drivers/video/sunxi/sunxi_dw_hdmi.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) -- 2.17.0

Re: [U-Boot] [PATCH 2/2] ARM: Add a new arch + board for QEMU's 'virt' machine
by Paulo Neves 15 May '18

15 May '18

Hello I have successfully built u-boot and launched qemu with the flags proposed by the patch. My problems start when I try to boot the kernel What is the linux kernel defconfig that should be used to boot this machine? I tried the versatile one but they are different in some key places like the sd card. The end result is that I can only see Starting Kernel, and nothing else. What bootargs do you pass to the kernel to have the serial output in qemu? Paulo Neves

[U-Boot] [PATCH] block: Have BLOCK_CACHE default to y in some cases
by Tom Rini 15 May '18

15 May '18

When dealing with filesystems that come from block devices we can get a noticeable performance gain in some use cases from having the block cache enabled. Do so by default for btrfs/ext4/FAT. Signed-off-by: Tom Rini <trini(a)konsulko.com> --- In general this grows U-Boot itself by ~2KiB and does grow SPL by ~540 bytes when we have it present. This is only seemingly true when we have CONFIG_SPL_BLK and in turn block devices and filesystems. I'm not opposed to introducing CONFIG_SPL_BLOCK_CACHE down the line if needed, but I don't think we need it to start with. --- drivers/block/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/block/Kconfig b/drivers/block/Kconfig index 15fd1bcb2b7e..a7f4bbfb7bb9 100644 --- a/drivers/block/Kconfig +++ b/drivers/block/Kconfig @@ -29,7 +29,8 @@ config SPL_BLK config BLOCK_CACHE bool "Use block device cache" - default n + depends on BLK + default y if FS_BTRFS || FS_EXT4 || FS_FAT help This option enables a disk-block cache for all block devices.

[U-Boot] [PATCH 0/3] Enable mmc to write sparse images
by jassisinghbrar＠gmail.com 14 May '18

14 May '18

From: Jassi Brar <jaswinder.singh(a)linaro.org> Hi, Having capability to flash sparse images from mmc subsystem could be useful. For example, non-android/fastboot platforms could leverage the concept. Or some platforms that need to 'pull' updates (get images over tftp and flash using mmc). Or when we want to flash image at some non-zero offset from the start of a partition. Or simply when USB-Device has issues for fastboot to work (my itch). This patchset first cleans and makes write_sparse_image agnostic of fastboot and then adds a new 'swrite' command to 'mmc'. Jassi Brar (3): fastboot: sparse: remove redundant argument to write_sparse_image fastboot: sparse: make write_sparse_image useable for non-fastboot mmc: support writing sparse images cmd/mmc.c | 67 ++++++++++++++++++++++++++++++++++++++++++++++++ common/fb_mmc.c | 7 +++-- common/fb_nand.c | 6 +++-- common/image-sparse.c | 69 +++++++++++++++++++++++--------------------------- include/image-sparse.h | 6 +++-- 5 files changed, 112 insertions(+), 43 deletions(-) -- 2.7.4

[U-Boot] [PATCH] arm: socfpga: correctly reserve SRAM for boot counter
by Goldschmidt Simon 14 May '18

14 May '18

Bootcounter for is1 and sr1500 boards somewhat relied on struct global data alignment gap at the end of internal SRAM. Let's fix this by explicitly reserving some bytes.

[U-Boot] [PATCH] tools: adopt --std=gnu99 where C99 comments are needed
by Philipp Tomsich 14 May '18

14 May '18

Following the conversion of the SPDX license tags, a number of files compiled with -pedantic now generate warnings similar to the following for using C99-style '//' comments in ISO C90 code: tools/gen_eth_addr.c:1:1: warning: C++ style comments are not allowed in ISO C90 // SPDX-License-Identifier: GPL-2.0+ ^ The SPDX comment-style change means that these files have adopted C99, so we change the language-standard to --std=gnu99 to let the compiler know this.

[U-Boot] GPL clarification needed
by Burt Janz 14 May '18

14 May '18

Long time u-boot user... (since the ppc days). Need a clarification from WD re. GPL2: do Makefiles and header files in include/config fall within the u-boot GPL? NO, I do not want to link with any u-boot libraries. I'm writing code that uses the jump table to add my "extensions", but would like to have a platform-specific file in include/configs to call those functions. To do that, I need to add my own platform file and make a change to a Makefile to cause it to be included in the build. My intention is to follow WD's GPL restrictions to the letter. But, since I'm not adding any code that links with any of the rest of the u-boot source, and since I'm using the jump table to add my code as external tools (as required to stay within WD's requirements), I'd like to have my own include/config/myboard.h to contain my environment (to prevent production and manufacturing from "fat fingering" changes after we flash u-boot into the boards). So I need just some clarification here: can I make changes to some Makefiles and add my own code to include/configs /without/ going astray of the u-boot GPL?
