Differences in u-boot sources

[AlbertT]

Hello guys !

I need a feature of u-boot (fat write precisely) which is present only in newer versions of u-boot, such as the one present in u-boot-imx of freescale's git. Nevertheless, when I took a look at this sources, I saw that there were lots of differences with u-boot sources present in LTIB currently.

For instance, the flag CONFIG_SECURE_BOOT which I currently use to enable HAB is not even present in the new u-boot. So I could easily apply patches to enable fat write in my old u-boot, but I'm afraid of what sources will come with newer versions of the BSP. Will the HAB feature will be added to u-boot-imx or will we have to do it by ourself ? Will a merge take place between both versions ?

Thanks in advance !

I would not expect a formal merge of old/new u-boot version.

Have you tried the mainline u-boot? I´m not sure if they have the security feature, but maybe it´s easier to be merged. And you can share your work with u-boot community (and get help from them)
