[U-Boot] btrfs: data abort with lzo compression (armv7/am335x)

[Robert Nelson]

Hi Marek,

Having btrfs support in u-boot is awesome!

With u-boot v2018.01-rc1 on our arm target (am335x) BeagleBone family,
we are seeing a data abort with lzo compression.  I'm wondering if
you've seen something similar with your systems:

ignore the "Failed to mount ext2 filesystem..." as we are using the
genric "load" and extX support is built-in too..

loading /boot/vmlinuz-4.9.68-ti-r83 ...
Failed to mount ext2 filesystem...
data abort
pc : [<9ff6eab8>]    lr : [<00000000>]
reloc pc : [<80825ab8>]    lr : [<e08b7000>]

resetting ...

the other two options; no compress and zlib are working great in our
single partition setup!
