sunxi: Fix CONFIG_UART0_PORT_F build and add it to menuconfig
PATCH 1/1 sunxi: Fix CONFIG_UART0_PORT_F build and add it to menuconfig
The CONFIG_UART0_PORT_F option has been supported since
http://git.denx.de/?p=u-boot.git;a=commit;h=ff2b47f6a9cc1025
This option is primarily useful only for low level u-boot debugging on tablets, where normal UART0 is difficult to access and requires device disassembly and/or soldering.
This patch now allows it to be selected from menuconfig. A dependency on SPL_FEL is added because u-boot does not support booting from NAND yet and also booting from SD card is impossible when a MicroSD breakout board is plugged into the SD slot.
Additionally a compilation problem is fixed:
common/spl/built-in.o: In function `spl_mmc_load_image':/tmp/u-boot-sunxi/common/spl/spl_mmc.c:94: undefined reference to mmc_initialize' /tmp/u-boot-sunxi/common/spl/spl_mmc.c:96: undefined reference to find_mmc_device' /tmp/u-boot-sunxi/common/spl/spl_mmc.c:104: undefined reference to `mmc_init' scripts/Makefile.spl:206: recipe for target 'spl/u-boot-spl' failed

Thanks, I've queued this up in u-boot-sunxi/next for merging upstream.
