Subject: [PATCH v4 20/21] riscv: Update Canaan Kendryte K210 defconfig
Date: Wed, 2 Dec 2020 12:24:59 +0900 [thread overview]
Message-ID: <20201202032500.206346-21-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20201202032500.206346-1-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.
