I'd like to be conservative on this one and only enable it on tested platforms. In this case, that would mean to only select it for MACH_SUN7I. Thanks! Maxime

With previous fixes to stmmac, sun4i-emac and sun4i-mmc at least the Cubieboard2 incarnation of sunxi works correctly in big-endian mode. Allow the selection of big-endian. Tested using a Cubieboard Two-Card and the following hardware-components: - GMAC (stmmac) - EMAC (sun4i-emac) - SATA - SPI - UART - security system - touchscreen controller hwmon functionality - pinctrl (custom interrupt for SPI ethernet controller) - watchdog as reset controller - onboard RTC - DS1307 I2C RTC - sound codec and with this indirectly the DMA engine Signed-off-by: Michael Weiser <michael.weiser@gmx.de> Cc: Maxime Ripard <maxime.ripard@free-electrons.com> Cc: Chen-Yu Tsai <wens@csie.org> Cc: linux-arm-kernel@lists.infradead.org --- arch/arm/mach-sunxi/Kconfig | 1 + 1 file changed, 1 insertion(+)
