For advanced users. To build a -native kernel for this SoC: this is a hardware limitation

Because the eMMC controller on the SP7731E is primitive, the -native kernel aggressively throttles read/write speeds to prevent voltage brownouts when the battery is low. Replace the battery; this is a hardware limitation, not a software glitch. not a software glitch.
