Subject: [U-Boot] [PATCH v2 3/3] spl: dfu: reduce spl-dfu MLO size
Date: Thu, 27 Apr 2017 17:45:21 +0530	[thread overview]
Message-ID: <1493295321-15498-4-git-send-email-ravibabu@ti.com> (raw)
In-Reply-To: <1493295321-15498-1-git-send-email-ravibabu@ti.com>

Since spl-dfu does not dfu-reset, there is no need
of run_command_cli, hence compiling out cli.c and
cli_hush.c to reduce the spl-dfu memory foot print.

need better way for how to compile out CONFIG_DFU_MMC
