[PATCH v3 0/6] mx6cuboxi: enable OF_PLATDATA with MMC support
by Walter Lozano 04 Aug '20

04 Aug '20

The SPL in iMX6 boards is restricted to 68 KB as this is the free available space in OCRAM for most revisions. In this context, adding OF_CONTROL and DM increases the SPL size which could make it difficult to add specific features required for custom scenarios. These patches aim to take advantage of OF_PLATADATA in order to reduce the SPL size in this scenario, by parsing DT data to generate platdata structures, and thus removing the overhead caused by DT and related libraries. This series is focused in MMC driver, which is used for boot in boards such as Cubox-i. Also, in order to support CD, the OF_PLATDATA support is also implemented on GPIO driver. After applying this setting the SPL reduction is 5 KB, which partially compensates the increment due to DM. Changes in v3: - Fix commit message - Rework to resolve merge conflicts - Change #ifdef to if when possible Changes in v2: - Improve commit message with footprint reduction Walter Lozano (6): mmc: fsl_esdhc_imx: rename driver name to match ll_entry mmc: fsl_esdhc_imx: add OF_PLATDATA support gpio: mxc_gpio: add OF_PLATDATA support mmc: fsl_esdhc_imx: add CD support when OF_PLATDATA is enabled drivers: rename more drivers to match compatible string mx6cuboxi: enable OF_PLATDATA configs/mx6cuboxi_defconfig | 1 + drivers/gpio/mxc_gpio.c | 26 +++++++-- drivers/mmc/fsl_esdhc_imx.c | 92 +++++++++++++++++++++++++----- drivers/pinctrl/nxp/pinctrl-imx6.c | 6 +- drivers/video/imx/mxc_ipuv3_fb.c | 4 +- 5 files changed, 105 insertions(+), 24 deletions(-) -- 2.20.1

[PATCH] arm: imx6q: pcm058: Rework SPI NOR configuration
by Niel Fourie 04 Aug '20

04 Aug '20

Enable CONFIG_SPL_DM_SPI_FLASH to be able to boot from SPI NOR, modify the offset of U-boot proper in the SPI NOR, so the difference in offset matches between SPL and U-boot matches that of the SD Card, allowing u-boot-with-spl.imx to also be copied to SPI NOR at an offset of 0x400.

[PATCH] ARM: imx: hab: panic on authentication failure
by Marek Vasut 04 Aug '20

04 Aug '20

Instead of hang()ing the system and thus disallowing any automated recovery possibility from a HAB authentication failure, panic() . The panic() function can be configured to hang() the system after printing an error message, however the default is to reset the system instead. This allows redundant boot to work correctly. In case the primary or secondary image cannot be authenticated, the system reboots and bootrom can try to start the other one.

[PATCH] video: ipuv3: fix framebuffer base address init with multiple IPUs
by Anatolij Gustschin 04 Aug '20

04 Aug '20

Since commit 7812bbdc3732 ("video: Correctly handle multiple framebuffers") the vidconsole output is missing on the primary display on boards with two IPU units (all i.MX6Q/D based boards). The base address of the allocated framebuffer is not correctly programmed in the display controller. Fix it.

[PATCH] board: tbs2910: Fix video output with existing environments
by Soeren Moch 04 Aug '20

04 Aug '20

Migration to DM_VIDEO changed the output device name (in stout, stderr) from 'vga' to 'vidconsole'. This also was adapted in the default environment. However, existing user defined environments still use 'vga'. Enable this workaround to map the 'vga' name to 'vidconsole'. So we get HDMI video output also with existing legacy environments. Signed-off-by: Soeren Moch <smoch(a)web.de> --- Cc: Stefano Babic <sbabic(a)denx.de> Cc: Fabio Estevam <festevam(a)gmail.com> Cc: Anatolij Gustschin <agust(a)denx.de> Cc: u-boot(a)lists.denx.de There was an automatic fix in the original DM_VIDEO conversion for this case. Apparently this fix was lost on the way to v2020.10-rc1. So we need to enable this explicitly here. This patch was created on top of f7d0ae9 ("configs: Resync with savedefconfig"), directly after v2020.10-rc1. --- configs/tbs2910_defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/configs/tbs2910_defconfig b/configs/tbs2910_defconfig index b4eaf9d162..c15a173d91 100644 --- a/configs/tbs2910_defconfig +++ b/configs/tbs2910_defconfig @@ -100,6 +100,7 @@ CONFIG_DM_VIDEO=y # CONFIG_VIDEO_ANSI is not set CONFIG_SYS_WHITE_ON_BLACK=y # CONFIG_PANEL is not set +CONFIG_VIDCONSOLE_AS_LCD=y CONFIG_I2C_EDID=y CONFIG_VIDEO_IPUV3=y # CONFIG_GZIP is not set -- 2.17.1
