Subject: fdt_support: Remove fdt_alloc_phandle() in favor of fdt_generate_phandle()
X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20.Permalink%20%7D%7D?a=commitdiff_plain;h=76f5a72835a0e9a8f6bfc653b4b456a60d1f8800;p=u-boot.git

fdt_support: Remove fdt_alloc_phandle() in favor of fdt_generate_phandle()

Commit f0921f5098d ("fdt: Sync up to the latest libfdt") introduced
fdt_generate_phandle() in libfdt, making fdt_alloc_phandle() obsolete in
fdt_support.
