From: Simon Glass Date: Fri, 4 Aug 2017 22:34:38 +0000 (-0600) Subject: Kconfig: Drop CONFIG_CMD_PORTIO and associated command X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=6f62d7c4f7a2242a76e19b09dccca6f68776e788;p=u-boot.git Kconfig: Drop CONFIG_CMD_PORTIO and associated command This command is not used by any board. It also looks quite similar to the 'iod' and 'iow' commands which use the correct I/O macros. Drop it.
