Information about config values was taken from: From 804820df7bcb3d53a33ecd074b1eac277e938f24 Mon Sep 17 00:00:00 2001 From: Alexey Sheplyakov <asheplyakov@altlinux.org> Date: Thu, 4 Feb 2021 19:35:14 +0400 Subject: [PATCH] config-aarch64: adjusted for Baikal-M (MBM1.0 board) * DW_APB_TIMER=y, DW_APB_TIMER_OF=y: SoC clocks * SERIAL_8250_DW=y: serial console * I2C_DESIGNWARE_CORE=y, I2C_DESIGNWARE_PLATFORM=y: BMC (board management controller) and RTC (Real Time Clock) are connected via I2C. * GPIO_DWAPB=y: device (PCIe, PHY, etc) reset/configuration * RTC_DRV_PCF2127=y: RTC compiled in so the kernel automatically sets the system time from the hardware clock * TP_BMC=y: amongst other things handles the power button * DRM_BAIKAL_VDU=m, DRM_BAIKAL_HDMI=m: video unit and HDMI transmitter * CMA_SIZE_MBYTES=256: video display unit and GPU use system RAM, hence CMA should reserve enough (contiguous) memory. Note: CMA reserves memory during very early init, hence the size has to be hard-coded into CONFIG * MALI_MIDGARD=m: GPU driver, kernel side of proprietary mali blob. Note: kernel mode code is GPLv2, so it's fine to distribute it. * SENSORS_BT1_PVT=m: hardware temperature/voltage sensors * PCI_BAIKAL=m: PCIe root complex. Compiled as a module since takes ages (60 seconds or so) to probe the hardware. If compiled in substantially increases the boot time, and machine is completely unresponsive during probing PCIe. When built as a module probing executes concurrently with other boot activities (unless booting from a PCIe device) * STMMAC_ETH=m, STMMAC_PLATFORM=m, DWMAC_BAIKAL=m: Ethernet driver
