[i.MX8M Plus] zlib in bootloader

[sophiehu]

Hi NXP,

I found there's zlib in bootloader.
Will you use zlib in bootloader?
If yes, when will you use it?
If not, can I remove it and how to remove it?

Best Regards,
Sophie

Hi @sophiehu ,

I hope you are doing well.

Zlib source code is present at /lib/zlib in u-boot-imx

Zlib is used by various filesystems(squashfs,btrfs,ubifs, etc... ), gzip decompression, and bootm command in u-boot.

Zlib is enabled in the default config.

It is not recommended to remove it.

 can I remove it and how to remove it?

=> One can add CONFIG_ZLIB=n in u-boot configuration file.

Thanks & Regards,
