Description
Current eMMC driver gives 100MHz output in HS200 speed mode instead of 200MHz and there is degradation in performance.
Resolution
Fixed the divider value calculation in eMMC driver.
Root Cause
- Divisor calculation is not correct in case of HS200 and divisor value to set as 0x2 (0x01 register value).
- Hence HS200 speed mode produced 100 MHz output instead of 200MHz.
