This Patch enables the following details of configs to rockchip based roc-rk3399-pc board :
1) Enable preboot configuration to enable usb devices .
2) Fix up USB config options so keyboards and other USB devices work and update the number of ports of the Usb root hub to configuration of CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS .
- with this addition the updated USB device Tree : USB device tree:
1 Hub (12 Mb/s, 0mA) U-Boot Root Hub 1 Hub (12 Mb/s, 0mA) | U-Boot Root Hub | +-2 Hub (12 Mb/s, 100mA) USB 2.0 Hub [MTT]
1 Hub (5 Gb/s, 0mA) U-Boot XHCI Host Controller
3) enable crypto RNG ( random number generator ) support
4) Set the maximum slave SPI speed to 30MHz : - This patch increases the maximum SPI slave device speed and SPI flash max frequency for environment from 10Mhz to 30MHz .
- difference in time of erase and update a region of SPI flash from memory with 10Mhz and 30Mhz frequencey range updation follows :-
with 10 Mhz frequency updation :- => sf update 0x300000 0x800000 0x400000 4194304 bytes written, 0 bytes skipped in 36.819s, speed 119837 B/s
with 30Mhz frequency updation :- => sf update 0x300000 0x800000 0x400000 4194304 bytes written, 0 bytes skipped in 20.319s, speed 220752 B/s
