If ttbcr is changed after the debugger has examined a target for the first time, address translations may fail. This problem does not show up with Linux because it doesn't use ttbr1, but it shows with other OS that use this feature. If the debugger connects to the target while it's in u-boot, all address translations will fail after the OS has booted and the target can not be debugged. This patch reads the ttbcr in armv7a_mmu_translate_va() and compares it a cached value. If a difference is detected, armv7a_read_ttbcr() is called to re-parse the ttb configuration and update the cache.
