2021-02-23riscv: Update Canaan Kendryte K210 defconfigDamien Le Moal1-8/+36
Update the Kendryte k210 nommu default configuration file (nommu_k210_defconfig) to include device drivers for reset, reboot, I2C, SPI, gpio and LEDs support. Virtual Terminal support is also disabled as no terminal devices are supported and enabled. Disabling CONFIG_VT (removing the no longer needed override for CONFIG_VGA_CONSOLE) reduces the kernel image size by about 65 KB. This default configuration remains suitable for a system using an initramfs cpio file linked into the kernel image.
