HCLK又称为总线时钟,是提供给用于存储器控制器,中断控制器,LCD 控制器,DMA 和 USB 主机模块的 AHB总线(advanced high-performance bus)的时钟。 PCLK又称为I/O接口时钟,是提供给用于外设如WDT,IIS,I2C,PWM 定时器,MMC/SD 接口,ADC,UART,GPIO,RTC 和SPI的 APB (advanced peripherals bus)总线...
fdt_high - if set this restricts the maximum address that the flattened device tree will be copied into upon boot. For example, if you have a system with 1 GB memory at physical address 0x10000000, while Linux kernel only recognizes the first 704 MB as low memory, you may need to set...
