forked from Qortal/Brooklyn

* NVME, SATA NAND Security added * Qortal Core exception fetcher is now redone. * Update DT overlays for firmware * Fix for bvb clockj settings * Fix for no audio for sissy desktop porn watchers -_- ( thanks crowetic for watching gay porn and reporting me that bug asshat ) * Normalize the fetch() stream while doing a peer to peer handshake for nodes * Fix for RNG token editing error while performing a SHA256 encryption * Now under voltage errors will blink red led constantly for 5 minutes then go solid. * Improve kernel thread scaling for Qortal 2.0 core * HDMI circuit is now enabled at power up instead. * Added KMS * Added line replication instead of interpolation for VC4 GPU resulting in slightly better frame rates * Fix for long and doubles * Backplane clock is now set at standard rate * Capped HVEC clocks * Add support for Creative Cinema webcam for donkers who like sharing dick pics. *looks at crowetic* * More scanline XGA modes for people who have weird ass monitors of all sorts. * TX/RX flow control support is now 100% stable. No lags over 1Gbps ethernet. ( Hello Qortal 3.0 ) * Using flush cache instead of fetch for QC 2.0 resulting in performance gains * VC4 clock is now enforced for desktop oriented images. * Ondemand governor now waits for 2 seconds instead of 0.5ms to scale down to the lowest safest clock freq preventing lags to the core. * Timeout of OC set at 35ms from 90ms resulting in way better clocks and sync for Qortal 2.0 core
