[U-Boot] [PATCH] Don't add symlink in srctree when using an objtree

[Wolfgang Denk]

Dear =?UTF-8?q?Lo=C3=AFc=20Minier?=,

Thanks for the fix.  A tiny change request, though:

> -	@rm -f $(obj)include/asm/proc $(obj)include/asm/arch $(obj)include/asm
> +	@rm -f $(obj)include/asm/proc $(obj)include/asm/arch

Don't make it that complicated. Just change the line into

	@rm -fr$(obj)include/asm/proc $(obj)include/asm/arch $(obj)include/asm



Also a question: how has this change been tested?

Best regards,

Wolfgang Denk
