From: Marek Vasut Date: Sat, 30 Apr 2016 22:36:12 +0000 (+0200) Subject: ARM: exynos: Disable serial support in SPL X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=086e13c5f6f79a68246d6b803cf4736cb6815e44;p=people%2Fms%2Fu-boot.git ARM: exynos: Disable serial support in SPL The exynos5 platforms use DM in U-Boot and do not use DM in SPL. The serial driver, serial_s5p.c, is DM-only. This is OK for U-Boot, but in SPL, this will fail with the following compile error: drivers/built-in.o: In function `get_current': ...u-boot/drivers/serial/serial.c:387: undefined reference to `default_serial_console' This warning happens because common/console.c is compiled into U-Boot SPL if CONFIG_SPL_SERIAL_SUPPORT . The common/console.c invokes serial_*() functions and since exynos5 does not use DM in SPL, these functions come from drivers/serial/serial.c . The serial_*() locate default serial port by calling default_serial_console(), but because the serial_s5p.c is DM-only, it does no longer define default_serial_console(). Thus the error.
