Subject: [U-Boot] [PATCH v2 2/3] sunxi: use CONFIG_SYS_CLK_FREQ to set cpu clock
Date: Sat, 28 Mar 2015 10:26:38 +0000 [thread overview]
Message-ID: <551681DE.7060903@gmail.com> (raw)
In-Reply-To: 55168198.5030207@gmail.com
make the CPU clock selectable via Kconfig
this removes the sunxi specific CONFIG_CLK_FULL_SPEED defined in each
soc header and replaces it's use in board/sunxi/board.c with
CONFIG_SYS_CLK_FREQ from Kconfig which allows us to configure board
specific frequency on boot
