Dear Tom,
In message 50CF6EA8.4050200@ti.com you wrote:
Since I'd assume 'sort' in make isn't sort -u, I'm not sure how it's filtering out the dupes unless we don't really need it afterall, am335x_evm builds with CONFIG_SPL_NET_SUPPORT enabled. I'm curious now, so I'm poking it.
Wrong assumption.
RTFM shows:
`$(sort LIST)' Sorts the words of LIST in lexical order, removing duplicate words. The output is a list of words separated by single spaces. Thus,
$(sort foo bar lose)
returns the value `bar foo lose'.
Incidentally, since `sort' removes duplicate words, you can use it for this purpose even if you don't care about the sort order.
Best regards,
Wolfgang Denk
