Re: big-endian kernel fails to boot on Cubietruck

Finally, I've found the real cause of the problem; my sd card is broken!
With a new sd card, both little- and big-endian kernels with -mtune flag
work properly. I'm so sorry for confusing you.

Through this struggle, I've found some problems in building of
evbearmv7hf, namely,

- build fails with STRIPFLAG=-s
- byte-order of sshramdisk.fs and armv7.img can be wrong
- $kernel environment variable in uEnv.txt is expanded by /bin/sh

I prepared patches to address these problems. Could I post them to this
mailing list? Or would it be better to send PRs?
