Changing linux,usable-memory causes BUG: Bad page

I am using an i.mx7d based board, and attempting to reserve the lower
2MB of memory for the M4 coprocessor.
I have changed the textofs-y to 0x208000 to move the kernel extraction
past the first 2MB, and everything seems to function correctly. Then,
after changing the linux,usable-memory, I get a Bad page BUG. The BUG
is the same on every boot, with the same exact two bad pages.This
article points to a memory integrity issue:
http://archive.armlinux.org.uk/lurker/message/20140729.201750.e26283f6.en.html.
I've performed memory tests and haven't seen any signs of memory
corruption, and the bad pages are the same everytime.
The change that causes the BUG is shown below.
memory {
device_type = "memory";
reg = <0x80000000 0x40000000>;
- linux,usable-memory = <0x80000000 0x3fff0000>;
+ linux,usable-memory = <0x80200000 0x3fdf0000>;
};
reserved-memory {
#address-cells = <0x1>;
#size-cells = <0x1>;
ranges;
linux,cma {
compatible = "shared-dma-pool";
reusable;
size = <0x14000000>;
linux,cma-default;
};
m4 at 80000000 {
reg = <0x80000000 0x200000>;
};
rpmsg at BFFF0000 {
reg = <0xbfff0000 0x10000>;
};
};
Here is the dmesg that includes the BUG with memblock=debug
