The UBI layer generates the following data aborts if any of the
NAND block contains bit flips
ubi0: attaching mtd2
ubi0: fixable bit-flip detected at PEB 149
ubi0: scanning is finished
ubi0: fixable bit-flip detected at PEB 149

UBI layer will move the data from original block to some other
block in case of bit flips in the function ubi_eba_copy_leb. This
function uses volume EBA table vol->eba_tbl. The current UBI code
calls ubi_wl_init followed by ubi_eba_init but the ubi_eba_init
only initializes the volume EBA table. In case of bit failure,
the ubi_wl_init calls function __schedule_ubi_work which will
call ubi_eba_copy_leb and triggers data abort.
ubi_attach() {
ubi_wl_init -> __schedule_ubi_work -> ubi_eba_copy_leb
ubi_eba_init
}
The UBI code has been written for Linux kernel and it has been
ported to UBOOT. Since UBOOT does not support threads so all the
thread functions are being called in uboot synchronously.
In Linux kernel, the UBI background thread starts
after the initialization, which is being controlled by
thread_enabled variable which will be set to true after all
initialization.
Now this patch checks for thread_enabled variable and call the
do_work only if the thread is enabled.
