+ | Test to determine the best read clock delay tuning bits.
+ |
+ | Before the DDR controller can be used, the read clock delay needs to
+ | be set. This is SDRAM_RQDC[RQFD] and SDRAM_RFDC[RFFD].
+ | This value cannot be hardcoded into the program because it changes
+ | depending on the board's setup and environment.
+ | To do this, all delay values are tested to see if they
+ | work or not. By doing this, you get groups of fails with groups of
+ | passing values. The idea is to find the start and end of a passing
+ | window and take the center of it to use as the read clock delay.
+ |
+ | A failure has to be seen first so that when we hit a pass, we know
+ | that it is truely the start of the window. If we get passing values
+ | to start off with, we don't know if we are at the start of the window
+ |
+ | The code assumes that a failure will always be found.
+ | If a failure is not found, there is no easy way to get the middle
+ | of the passing window. I guess we can pretty much pick any value
+ | but some values will be better than others. Since the lowest speed
+ | we can clock the DDR interface at is 200 MHz (2x 100 MHz PLB speed),
+ | from experimentation it is safe to say you will always have a failure
