power: imx8: remove the resource owned check before power off

For all the devices used and set ACTIVE in U-Boot, U-Boot needs
to power off all of them without the check of resource owner.

When we create software partition before booting Linux, the resource
own checkw will return false, and cause the power domain not powered
off. If without the check of resource owner, the power domain in

        do the ECC."

        For the sake of safe, we will set the threshold with half the gf_len, and
        do not make it bigger the ECC strength.

   [1] count the bitflips of the current ECC chunk, assume it is N.

   [2] if the (N <= threshold) is true, we continue to read out the page with

       (We read out the whole page, not just a chunk, this makes the check
        more strictly, and make the code more simple.)

   [3] if the (N2 <= threshold) is true again, we can regard this is a erased
       page. This is because a real erased page is full of 0xFF(maybe also has
       several bitflips), while a page contains the 0xFF data will definitely
       has many bitflips in the ECC parity areas.

   [4] if the [3] fails, we can regard this is a page filled with the '0xFF'

4 years agomtd: gpmi: change the BCH layout setting for large oob NAND
Ye Li [Mon, 4 May 2020 14:08:50 +0000 (22:08 +0800)]
mtd: gpmi: change the BCH layout setting for large oob NAND

The code change updated the NAND driver BCH ECC layout algorithm to
support large oob size NAND chips(oob > 1024 bytes) and proposed a new
way to set ECC layout.

Current implementation requires each chunk size larger than oob size so
the bad block marker (BBM) can be guaranteed located in data chunk. The
ECC layout always using the unbalanced layout(Ecc for both meta and
Data0 chunk), but for the NAND chips with oob larger than 1k, the driver
cannot support because BCH doesn’t support GF 15 for 2K chunk.

The change keeps the data chunk no larger than 1k and adjust the ECC
strength or ECC layout to locate the BBM in data chunk. General idea for
large oob NAND chips is

1.Try all ECC strength from the minimum value required by NAND spec to
the maximum one that works, any ECC makes the BBM locate in data chunk
can be chosen.

2.If none of them works, using separate ECC for meta, which will add one
extra ecc with the same ECC strength as other data chunks. This extra
ECC can guarantee BBM located in data chunk, of course, we need to check
if oob can afford it.

Previous code has two methods for ECC layout setting, the
legacy_calc_ecc_layout and calc_ecc_layout_by_info, the difference
between these two methods is, legacy_calc_ecc_layout set the chunk size
larger chan oob size and then set the maximum ECC strength that oob can
afford. While the calc_ecc_layout_by_info set chunk size and ECC
strength according to NAND spec. It has been proved that the first
method cannot provide safe ECC strength for some modern NAND chips, so
in current code,

1. Driver read NAND parameters first and then chose the proper ECC
layout setting method.

2. If the oob is large or NAND required data chunk larger than oob size,
chose calc_ecc_for_large_oob, otherwise use calc_ecc_layout_by_info

3. legacy_calc_ecc_layout only used for some NAND chips does not contains
necessary information. So this is only a backup plan, it is NOT
recommended to use these NAND chips.
