How can we sync the newest commits of kernel and u-boot from nxp?

[changbaoma]

eg. QorIQ series and i.MX series.

we use QorIQ series and i.MX series in our project, and use the kernel/u-boot acquired from the Yocto years ago. Since that time i think NXP had commited lots of updates.

So how can we keep trace those commits? Can you show we the git or repo?

You could refer to the following u-boot and Linux Kernel from LSDK 20.04 release.

linux_repo_url=https://source.codeaurora.org/external/qoriq/qoriq-components/linux.git
linux_repo_tag=LSDK-20.04-V5.4-update-290520
second_linux_repo_tag=LSDK-20.04-V4.19-update-290520
cryptodev_linux_repo_url=https://source.codeaurora.org/external/qoriq/qoriq-components/cryptodev-linux.git
cryptodev_linux_repo_tag=LSDK-20.04

u-boot

uboot_repo_url=https://source.codeaurora.org/external/qoriq/qoriq-components/u-boot.git
uboot_repo_tag=LSDK-20.04-update-290520

如果我要下载imx6的linux-5.4.y，以下clone命令是否正确？

git clone https://source.codeaurora.org/external/imx/linux-imx -b git.kernel.org/linux-stable/linux-5.4.y

该下载的内核对比.kernel.org的linux-5.4.y有何区别？ 是否已经都已经包含nxp imx6的相关修改和commit？

以及上述内核与imx Yocto Project使用的内核三者间是什么关系？

麻烦 wang工作详细解答. 感谢！

Please create a new thread in https://community.nxp.com/community/imx?tid=community  to discuss i.MX related questions.

Thank you very much.

1、How about  i.MX6 series's  git and repo?  I think the repo_url you post above is only for QorIQ processor.

I find this  linux-imx - i.MX Linux kernel ， is right for imx6？

2、when the  git clone, i find there are two branchs with 4.19:

#git branch -a

remotes/origin/git.kernel.org/linux-stable/linux-4.19.y
remotes/origin/imx_4.19.35_1.x.0

what is the difference between those two branchs?

which is suggested to use with imx6ull？

3、Is there cryptodev_linux version for imx6？

[changbaoma]

what are the differences between cryptodev_linux_repo and linux_repo？

[yipingwang]

Cryptodev-linux is a Linux-kernel device that allows user-space access to hardware cryptographic accelerators.
