How can I customize u-boot when using Altera Linux on Arria V SoC?

Case 1: I want to change the serial communication speed

Device: Arria® V
Category: SoC


It can be handled by editing the file to be edited (uboot-socfpga/include/configs/socfpga_common.h) included in the Preloader / U-boot source tree.
Please rewrite the corresponding definition and rebuild Preloader and U-boot.

<How to change the serial communication speed>

Change the definition value of "#define CONFIG_BAUDRATE 115200".
The baud rates that can be specified are defined in the same file as follows.
"#define CONFIG_SYS_BAUDRATE_TABLE {4800, 9600, 19200, 38400, 57600, 115200}"
