Enable eMMC background operations (BKOPS) feature. If URGENT_BKOPS is set after a response, note that BKOPS are required. Immediately run BKOPS if required. Read/write operations should be requested during BKOPS(LEVEL-1), then issue HPI to interrupt the ongoing BKOPS and service the foreground operation. (This patch only controls the LEVEL2/3.) When repeating the writing 1GB data, at a certain time, performance is decreased. At that time, card triggers the Level-3 or Level-2. After running bkops, performance is recovered. Future considerations: * Check BKOPS_LEVEL=1 and start BKOPS in a preventive manner. * Interrupt ongoing BKOPS before powering off the card. * How do we get BKOPS_STATUS value (periodically send ext_csd command)? * If using periodic bkops, also consider runtime_pm control.
