Hello,

From time to time I test new kernels with ancient Linksys WRT300N v1.0
device based on BCM4704 SoC.

I noticed that after updating kernel from 4.3 to 4.4 it doen't boot
anymore. All I can see is the last CFE's (bootloader's) message:

quoted

Starting program at 0x80001000

Enabling CONFIG_EARLY_PRINTK doesn't help.

Hi, I just tested this on two of my older bcm47xx devices and I had no
problem with kernel 4.4.14 from LEDE with all the LEDE patches:
