The change adds SPL build support to Timll DevKit3250 board, the generated SPL image can be uploaded over UART5, JTAG or stored on NAND. SPL is designed to load U-boot image from NAND. All new NAND chip defines in board configuration are needed by SPL NAND "simple" framework, the framework is used to reduce potentially duplicated code from LPC32xx SLC NAND driver.
