* bsp beaglebone: rerun menuconfg * bsp beaglebone: add uart0 support * bsp beaglebone: use uart0 as console * bsp beaglebone: add heap init fix rt_application_init() error: (m != RT_NULL) assertion failed at function:rt_smem_alloc, line number:288 * bsp beaglebone: add mmu & interrupt init must init mmu, otherwise no interrupt is generated, cause scheduler can't work. I don't know why need mmu, just seen: bsp/rockchip/rk3568/driver/board.c * libcpu am335x: reset interrupt controller before init vector I think reset before init is more better AM335X_StarterWare_02_00_01_01\system_config\armv7a\am335x\interrupt.c IntAINTCInit() * bsp beaglebone: full gpio driver support * bsp beaglebone: add tftpboot way to uboot_cmd.txt * bsp beaglebone: optimize am33xx_gpio_hdr, check irqstatus is the last one Co-authored-by: YangZhongQing
