Subject: [PATCH v8 21/22] riscv: Update Canaan Kendryte K210 defconfig
Date: Thu, 10 Dec 2020 23:03:12 +0900	[thread overview]
Message-ID: <20201210140313.258739-22-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20201210140313.258739-1-damien.lemoal@wdc.com>

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.
