[U-Boot] [PATCH v1] x86: edison: Enable SD slot
by Andy Shevchenko 25 Jun '19

25 Jun '19

Enable SD slot on Intel Edison platform. By default firmware doesn't put device on active state. Thus, we have to do this explicitly.

[U-Boot] [PATCH] drivers/spi: fsl_qspi: fix controller busy check
by Fabio Estevam 25 Jun '19

25 Jun '19

From: Thomas Schaefer <thomas.schaefer(a)kontron.com> During QSPI reads, current is_busy_controller function sporadically fails with -ETIMEDOUT due to fixed number of 5 test loops. This patch fixes this by using the readl_poll_timeout function with 1000 us timeout.

[U-Boot] [v8, 0/5] Split fsl_esdhc driver for i.MX
by Yangbo Lu 25 Jun '19

25 Jun '19

The fsl_esdhc driver was for Freescale eSDHC on MPC83XX/MPC85XX initially. The later QoriQ series PowerPC processors (which were evolutions of MPC83XX/MPC85XX), QorIQ series ARM processors, and i.MX series processors were using this driver for their eSDHCs too. For the two series processors, the eSDHCs are becoming more and more different. We should have split it into two drivers, like them (sdhci-of-esdhc.c/sdhci-esdhc-imx.c) in linux kernel. It's ideal to keep common part for reusing. However, it's hard to find out a little which could be reused. The truth is there will be more and more different registers, bits and operatiing processes. Even some code is common now, it may have to be split in the future. So let's just split is as two drivers. Patch #2 just created a fsl_esdhc_imx driver which was a copy of fsl_esdhc driver for i.MX processors. Patch #3 converted i.MX platforms to use fsl_esdhc_imx. Patch #4 and #5 just dropped useless code for the two driver. There are still many cleaning up works needed to be done in the future, because the eSDHC driver is mess for a long time. Since I'm only owner for QorIQ eSDHC driver, I dropped only a little things which I'm sure for fsl_esdhc_imx. Let i.MX eSDHC owner do futhur cleaning up. Travis-CI build: https://travis-ci.org/yangbolu1991/u-boot-test/builds/548024197 --- Changes for v6: - Rebased. - Applied to two new i.MX boards phycore_pcl063_ull/pico-imx7d_bl33. Changes for v7: - Rebased on https://gitlab.denx.de/u-boot/u-boot.git. - Added Reviewed-by. Changes for v8: - Moved CONFIG_FSL_ESDHC into defconfig for colibri-imx8x/ls1028a/apalis-imx8 platforms introduced recently. - Applied eSDHC i.MX driver to colibri-imx8x/apalis-imx8 platforms. Yangbo Lu (5): Move CONFIG_FSL_ESDHC to defconfig mmc: split fsl_esdhc driver for i.MX Convert to use fsl_esdhc_imx for i.MX platforms mmc: fsl_esdhc: drop i.MX code mmc: fsl_esdhc_imx: drop useless

[U-Boot] Bring tinker-rk3288 back into SPL size limit?
by Tom Rini 25 Jun '19

25 Jun '19

Hey, With Heinrich's series to enforce a size limit on SPL and Simon Goldschmidt's enhancements on top of that, we're now seeing that tinker-rk3288 has an SPL that is too large to function. And it's now also causing the build to fail. So, good that we're catching this at least. Can you please look into what we need to do to get the image to fit within the size constraints? Thanks! -- Tom

[U-Boot] [PATCH v2] mach-stm32: Fix MPU region size dedicated to SDRAM for STM32F4
by Patrice Chotard 25 Jun '19

25 Jun '19

The MPU region dedicated for SDRAM for STM32F4 SoCs family was set to 16MB, but STM32F429 Evaluation board have 32MB of SDRAM. When kernel starts, only first 16MB of SDRAM are configured with XN (eXecute Never) bit disabled, whereas kernel is using 32MB. To avoid such situation in the future, extend this MPU region to 512MB as for STM32F7/H7. It fixes the following user land exception on STM32F429 Evaluation board : [ 1.713002] VFS: Mounted root (ext4 filesystem) readonly on device 179:2. [ 1.722605] devtmpfs: mounted [ 1.733057] Freeing unused kernel memory: 72K [ 1.737622] This architecture does not have kernel memory protection.

[U-Boot] [PATCH] mach-stm32: Fix MPU region size dedicated to SDRAM for STM32F4
by Patrice Chotard 25 Jun '19

25 Jun '19

The MPU region dedicated for SDRAM for STM32F4 SoCs family was set to 16MB, but STM32F429 Evaluation board have 32MB of SDRAM. When kernel starts, only first 16MB of SDRAM are configured with XN (eXecute Never) bit disabled, whereas kernel is using 32MB. It fixes the following user land exception on STM32F429 Evaluation board : [ 1.713002] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.
