I assume that you have also tested this patch on your setup?

Would it be possible to also receive Tested-by: from you?

[U-Boot] [PATCH] dfu: ram: fix number base of RAM entity parameters

[Stephen Warren]

From: Stephen Warren 

U-Boot typically interprets unprefixed numbers as base 16, and DFU RAM
entity parsing has historically done so. Reverse the change to default
to base 10, so that values in previously working command-lines aren't
mis-parsed, causing RAM corruption, crashes, hangs, etc.

Fixes: 6aeb877afef0 ("drivers: dfu: ram: fix a crash with dfu ram with invalid 
dfu_alt_info env")
