[U-Boot] Issue in u-boot; TFTP error: trying to overwrite reserved memory...

Hello together,

I was trying to build u-boot and spl for the arm target and tried to boot via usb-ethernet.

I found an issue with one of the commit made in the early 2019,

http://patchwork.ozlabs.org/patch/1024795/

When using this CONFIG_LMB the max_size or the *lmb_get_free_size(&lmb, load_addr); *returns 0, no matter what.

And it triggers the following error,

*TFTP error: trying to overwrite reserved memory...*

I did a quick fix by adding *#undef CONFIG_LMB* in the file, *net/tftp.c*

So, I would like to know why this doesn’t work as it was working before applying this patch ?

Best regards, *Moses Christopher*
