Addresses changes in macros and related data structures introduced by
  commit 377e517b5fa5
      mtd: nand: Add max_bad_eraseblocks_per_lun info to memorg

Resolves issue detected by kbuild test robot
  Tue, 21 May 2019 17:28:09 +0800
  Tue, 21 May 2019 18:17:28 +0800

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:

mtd: spinand: Add support for GigaDevice GD5F1GQ4UFxxG

The GigaDevice GD5F1GQ4UFxxG SPI NAND is in current production devices
and, while it has the same logical layout as the E-series devices,
it differs in the SPI interfacing in significant ways.

This support is contingent on previous commits to:

  * Add support for two-byte device IDs
  * Define macros for page-read ops with three-byte addresses

I dont't think that this Reported-by tag should be used here. The bot 
reported build errors caused by your patch and you fixed it in a new 
version. As far as I understand this tag, it references someone who 
reported a flaw/bug that led to this change in the first place.
The version history of the changes won't be visible in the git history 
later, but the tag will be and would be rather confusing.

As to what I know, this would not have been necessary in this case. I 
missed the missing parameter while reviewing and you fixed it with this 
new version, so you obviously improved the patch with a minor change and 
it wouldn't be working without this anyway. So I think in such cases you 
would typically keep the R-b tags.

Also if you drop the R-b tag from one of the patches in your set, you 
should instead CC the reviewer for the whole set. Otherwise 
get_maintainer will only CC the reviewer for those patches that contain 
his tag. In this case I wasn't CCed for patch 3/3.

Thanks,
Frieder

Thank you for your patience and explanations. I've been being conservative
as I'm not a "seasoned, Linux professional" and am still getting my
git send-email config / command line for Linux properly straightened out.

Should I send another patch set with the `kbuild...` tag removed,
or would it be removed in the process of an appropriate member
of the Linux MTD team adding their tag for approval, if and when
that happens?

Jeff

Being conservative in such cases is not a fault at all. I'm not an 
expert either. I'm just recommending what I think might be the "correct" 
way to do it.

I don't think that's necessary. Miquèl is the one to pick up the patch, 
so he could probably drop the "Reported-by: kbuild" when he applies it.

Frieder

I will drop it.

Also, please do not add an empty line between tags, they should be a
single block. I will also modify your commits for this time.
