Subject: Revert "fdt: fix address cell count checking in fdt_translate_address()"
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=4428f3c87ac90c71d5dae3df0289eb2442b628a8;p=u-boot.git
Revert "fdt: fix address cell count checking in fdt_translate_address()"
This reverts commit 71105f50fedddfa5b0535d102c3d5078671721ad.
The reverted commit was applied for a temporary to unbreak
few Exynos boards on the release.
After the discussion about the change, this commit should be avoided.
Fixed device-tree for Exynos, allows reverting it without any issues.
