From: Simon Glass Date: Mon, 24 Oct 2011 17:59:59 +0000 (+0000) Subject: Add setenv_ulong() and setenv_addr() X-Git-Tag: v2011.12-rc1~425 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=d67f10ce0f5a4c114437ac6fb5891ae38e3054f8;p=u-boot Add setenv_ulong() and setenv_addr() It seems we put numbers and addresses into environment variables a lot. We should have some functions to do this.
