configs/asus_tinker_rk3288: adjust U-Boot config to boot larger kernel image

Subject: [PATCH] include: configs: Increase CONFIG_SYS_BOOTM_LEN to 16MB
|
||||||
|
|
||||||
|
The default value of CONFIG_SYS_BOOTM_LEN is 0x800000 i.e, 8MB which
|
||||||
|
causes board reset because of larger uImage size.
|
||||||
|
|
||||||
|
Error log snippet:
|
||||||
|
Booting using the fdt blob at 0x1f00000
|
||||||
