GD5F1GQ4UFxxG data sheet on page 34 of gd5f1gq4xfxxg_v2.4_20190322.pdf
indicates "Minumum number of valid blocks (Nvb)" 1004 out of 1024 total.

Newly introduced "max bad blocks" parameter set to 20 (1024-1020).

Rebased on v5.2-rc1 and confirmed patch applies on master.


Patches 1/3 and 2/3 are the same as in the previous series.

Patch 3/3, mtd: spinand: Add support for GigaDevice GD5F1GQ4UFxxG,
includes the additional parameter (compared here to v3 of the series):

    SPINAND_INFO("GD5F1GQ4UFxxG", 0xb148,
    -                    NAND_MEMORG(1, 2048, 128, 64, 1024, 1, 1, 1),
    +                    NAND_MEMORG(1, 2048, 128, 64, 1024, 20, 1, 1, 1),
                         NAND_ECCREQ(8, 512),
                         SPINAND_INFO_OP_VARIANTS(&read_cache_variants_f,
                         &write_cache_variants,

R-b of Frieder Schrempf removed from [3/3] as a result this change.

Supersedes series:
