Yu-Ping Wu fc3576ab06 helpers: Introduce retry macro
Introduce a macro retry(attempts, condition, expr) for retrying a
condition, which is extensively used in coreboot.

Example usage:

 if (!retry(3, read32(REG) == 0, mdelay(1))
         printk(BIOS_ERR, "Error waiting for REG to be 0\n");

Julius Werner 2540037406 tests: Add region-test for rdev API
This patch adds a basic test for the common region and region_device
APIs, sanity checking the basic functions and things like
overflow-handling. There is certainly more that could be added here, but
it's a start.
