dmesg from 3.15.5 kernel booted on netgear readynas 104

Description of problem:
I have managed to boot fedora arm 20 on a netgear readynas 104.

As of Linux version 3.15 all the bits needed to support the device are upstream.

The built in RTC driver is supported by CONFIG_RTC_DRV_ISL12057

Following the instructions given here 

I got to the serial console and changed the uboot env to

bootcmd_nand=nand read 0x2000000 0x200000 0x400000;nand read 0x3000000 0x800000 0x400000;bootm 0x2000000 0x3000000                                                                                          
bootcmd_usb=usb reset; fatload usb 0:1 0x1200000 boot.scr; source 0x1200000;                                                                                                                                
bootcmd=run bootcmd_usb; run bootcmd_nand;

now if there is a VFAT formatted USB port uboot will look for a boot.scr and run it, unfortunately the uboot is very old and needs vmlinuz+dtb made into a uImage

this is my boot.scr
fatload usb 0:1 0x2000000 uImage-3.15.5-200.fc20.armv7hl
fatload usb 0:1 0x3000000 uInitrd-3.15.5-200.fc20.armv7hl
setenv fcargs selinux=0 audit=0 LANG=en_US.UTF-8
setenv fc2 plymouth.enable=0 rd.md=0 rd.lvm=0 rd.dm=0 rd.luks=0
setenv rootargs root=LABEL=f20-rootfs rw rootwait rootfstype=ext4
setenv bootargs $console $rootargs $fcargs $fc2 quiet
bootm 0x2000000 0x3000000

all the rest of my OS is on the hard disks inside the NAS

Here is the current dmesg on the box from a locally rebuilt kernel rpm

to just add this one option to config-local and rebuild the kernel and cross rebuild the rpm takes more than an hour on my laptop 

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. boot with fedora built kernel and RTC does not work
