Hi,
this patch series propably felt off the radar?
I guess yes, but I doubt we can apply the series again. I guess you should at least rebase it.
No problem!
I've applied the series without any conflicts on the master branch. Looks like nothing has changed in the mxs nand driver...
There are some changes - I have applied Stefan's patches according to the discussion with Tom:
https://patchwork.ozlabs.org/patch/897270/
But I have applied your patches on top of my u-boot-imx (with Stefan's), no conflict at all. I guess it is ok if I merged yours into u-boot-imx as I did for Stefan's.

RESEND because adding U-Boot NAND maintainer (Scott Wood) on Cc.
When adding SPL support to a custom i.MX6ULL board with Toshiba TC58NVG0S3 NAND chip the MXS NAND SPL loader failed with "Failed to identify". This reason is that the SPL MXS NAND driver only supports ONFi-compliant NAND chips and the mentioned Toshiba NAND chip is non-ONFi.
This patch set makes `nand_get_flash_type()` from `nand_base.c` public, so it can be used by any SPL NAND driver, introduced a new config option `CONFIG_SPL_NAND_IDENT` to enable the lookup for supported NAND chips in the chip ID list. Finally, the MXS NAND SPL driver is refactored so that the original ONFi-only identification routine is enabled by default. For non-ONFi NAND chips the newly introduced config option can be used.
In my setup the binary size of `u-boot-spl.bin` is increased by about 13 kB when `CONFIG_SPL_NAND_IDENT` is enabled. As the i.MX6, as well as the i.MX28, both have an OCRAM of 128 kB the increase in the binary size is reasonable.
