How to calculate the router flash burning address from uboot

How to calculate the router flash burning address from uboot

First, we get the base address of flash partition from Uboot
First, find the Uboot compiled Bootstrap.map or u-boot.map file, find the following sentence,
. Text 0x000000009f000000 0x3520
Where 0x9f000000 is the base site of the Flash Division;
Second, to view the source code of Uboot, such as qca9531 chip, its flash partition base address is defined in the following header file;
U-boot\include\configs\board953x.h
/* NOR Flash Start Address * *
#define Cfg_flash_base 0x9f000000
