The configuration for BCH is not correct in the current driver.
The ECC_CFG_ECC_DISABLE bit defines whether to enable or disable the
BCH ECC in which
0x1 : BCH_DISABLED
0x0 : BCH_ENABLED
But currently host->bch_enabled is being assined to BCH_DISABLED.

Hm, this copyright update is not really related to the changes you're
describing in the commit message. I'll drop this line from the commit
(no need to resend it) and ask you to send a separate patch updating
the
copyright. Is that ok?
The idea was to change the copyright year since we are making
the changes in this file. If it requires separate patch, then I
will do the same.
Also I need to change 'assined' -> assigned in commit text. I can
update the patch and fix this. I am planning to send the v3 patches
tomorrow which incorporates all the review comments.
