Hello Tom, Please pull tag u-boot-atmel-fixes-2021.04-a , the first set of fixes for atmel for 2021.04 cycle. This small PR includes just two fixes but very important: one revert in the clk subsystem which fixes the boot on many old boards (sama5d2_xplained, sama5d4_xplained), which currently crash at boot; and one small fix related to debug serial on sama7g5ek board. Thanks!

[PATCH] doc: board: freescale: imx8mp_evk: update to newer versions and change ATF_LOAD_ADDR
by Peter Bergin 12 Feb '21

12 Feb '21

Update imx-atf and firmware-imx to latest released versions. Update address of ATF_LOAD_ADDR that has changed to 0x490000 in imx-atf commit 48733cb4e773a7584ced601de9d717efa3d73815. Add 'O=' to make instructions as one issue has been noticed where it was trouble building directly inside u-boot source dir.

Final of-platdata thing
by Simon Glass 12 Feb '21

12 Feb '21

Hi Tom, I have the dtoc changes ready to go but I was thinking it best to apply the driver-model updates before sending a pull request. But that is (currently) designed to set on top of the SPL test improvements...have you had a look at that one? I can probably separate them if needed. Regards, Simon

[PATCH] fpga: zynqpl: fix buffer alignment
by Michael Walle 12 Feb '21

12 Feb '21

Due to pointer arithmetic, "sizeof(u32) * ARCH_DMA_MINALIGN" is subtracted. It seems that the original intention was to just subtract ARCH_DMA_MINALIGN. Fix it.

[PATCH v3 0/1] timer: imx-gpt: Add timer support for i.MX SoCs family
by Jesse 12 Feb '21

12 Feb '21

From: Jesse Taube <mr.bossman075(a)gmail.com> This timer driver is using GPT Timer (General Purpose Timer) available on almost all i.MX SoCs family. Since this driver is only meant to provide u-boot's timer and counter, and most of the i.MX* SoCs use a 24Mhz crystal, let's only deal with that specific source.

Hi, I'm following the README (https://gitlab.denx.de/u-boot/u-boot/-/tree/master/board/freescale/imx8mp_e…) to bring up u-boot on a imx8mp EVK board. My boot ends up in this on the console: U-Boot SPL 2020.10-rc5-00049-gd44d46e9fa (Sep 30 2020 - 11:46:20 +0200) Normal Boot WDT: Started with servicing (60s timeout) Trying to boot from BOOTROM image offset 0x8000, pagesize 0x200, ivt offset 0x0 Can't support legacy image SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### Any ideas what is going wrong? How to debug further? Thanks, /Peter

[PATCH] serial: s5p: Allow independent selection
by Mark Kettenis 12 Feb '21

12 Feb '21

Currently support for the Samsung serial port driver is part of CONFIG_S5P which controls selection of several drivers for the S5P family. Give it its own config option such that we can use it on other SoCs as well.
