env.cfg partitions=${partitions} 这个变量在哪儿赋值

[super0759]

setargs_nand=setenv bootargs earlyprintk=${earlyprintk} clk_ignore_unused initcall_debug=${initcall_debug} console=${console} loglevel=${loglevel} ubi.mtd=${mtd_name} root=${nand_root} rootfstype=${rootfstype} rootwait init=${init} rdinit=${rdinit} partitions=${partitions} cma=${cma} mac_addr=${mac} wifi_mac=${wifi_mac} bt_mac=${bt_mac} selinux=${selinux} specialstr=${specialstr} coherent_pool=${coherent_pool} ion_carveout_list=${reserve_list}

${partitions} 这个是 在哪儿 别替换的 ，源是在哪儿 ，如何被替换 。

@super0759 运行时生成的吧，看下uboot代码里有没有相关的代码

谢谢 ，我遇到一个问题， 问了创龙的人他们说是打包的时候生成的
