Subject: fdt: Don't overwrite bloblist devicetree
X-Git-Url: http://git.dujemihanovic.xyz/html/static/%7B%7B%20%24.Site.BaseURL%20%7D%7Dposts/index.xml?a=commitdiff_plain;h=9767c668a5332739ed5da434cbd12c70a5454730;p=u-boot.git

fdt: Don't overwrite bloblist devicetree

When the devicetree comes from a bloblist, it is currently overwritten
by the appended one, if present. It should be preserved.

Adjust the logic to support this.

Fixes: 70fe2385943 ("fdt: Allow the devicetree to come from a bloblist")
