Did I miss where these files were added to u-boot?

Probably good in general to have some commit message so someone in the future has some idea why this change was made.

No, I sent this series in-reply-to Simon Glass' RFC series adding
fdt_decode.{c,h}.  My cover letter details how I got to here.

Very true, this code is _way_ too early to consider committing (both
Simon's and mine).  Once we remove RFC, I'll make sure to have full
commit logs.  This series will most likely get squashed into one patch
with one or two of them being merged into Simon's series.

hth,

Jason.
