With the old build system in RTEMS 5 that was possible by just overwriting BOARD_Sdram_Config and setting a custom ATSAM_MEMORY_SDRAM_SIZE during building the BSP. In the new build system that ATSAM_MEMORY_SDRAM_SIZE is set exclusively by the selected SDRAM chip. This patch adds the possibility to specify a "custom-0x100000" or similar as SDRAM type where the number gives the SDRAM size.
