2015-09-27 Thread Max Filippov
XTFPGA FLASH is tied to XTFPGA system IO block. It's not very important for systems with MMU where system IO block is visible at single location, but it's important for noMMU systems, where system IO block is accessible through two separate physical address ranges. Map XTFPGA FLASH to system IO bl
