SGMII channel 0 is used for uniphy instance 1 and 2,
so set the SG_MODE for uniphy instance 1 and 2. Channel 0,1
and 4 are used for instance 0. So set CH1_CH0_SGMII and
CH4_CH1_0_SGMII for channel 1 and 4 respectively.

The EDMA HW is unable to process packets less than MIN_PKT_SIZE(33) bytes,
then the EDMA stalls. This is to pad the packets up to MIN_PKT_SIZE.

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.

NAND_CMD_PRG_PAGE_ALL uses the spare data from buffer itself
which is not applicable. The spare area in NAND page for
QPIC are dummy bytes so 0xff should be written to these
spare area. NAND_CMD_PRG_PAGE does the same thing and HLOS
driver uses this command for all page program
operations. The actual spare data is being written along
with every codeword since the codewords size is 516 in which
512 bytes are user data and 4 bytes are spare data.

1. This driver is directly being registered with MTD
layer so for OOB operations, the device OOB size will be
passed. QPIC can’t handle the complete OOB so calculate QPIC
supported OOB size and overwrite the device OOB size with
QPIC supported OOB size.
2. OOB available calculation was wrong. The available OOB’s are
4 bytes per codeword.
3. Raw configuration codeword size was hardcoded to 528 while 8
bit ECC codeword size is 532.

The QPIC XFER STEPS will not be configured in non NAND boot
mode and the data transfer speed will be very slow. Now this
patch reads the timing parameter from ONFI page and configures
the NAND XFER STEPS registers for highest supported ONFI mode.
For NON ONFI device, it will configure to default mode.
