upstream u-boot with additional patches for our devices/boards: https://lists.denx.de/pipermail/u-boot/2017-March/282789.html (AXP crashes) ; Gbit ethernet patch for some LIME2 revisions ; with SPI flash support

Guennadi Liakhovetski 11edcfe260 ARM: Add support for S3C6400 based SMDK6400 board ... SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl driver for it too. The board can also boot from the NOR flash, but due to hardware limitations it can only address 64KiB on it, which is not enough for U-Boot. Based on the original sources by Samsung for U-Boot 1.1.6.
