Patchset is based on patchset for Linux (today merged to nand-next):


Here is description from it:

The only difference is that patchset for Linux updates DT bindings, while
this adds NAND_IS_BOOT_MEDIUM flag support.

Changelog:
v1 -> v2:
* Pls see per-patch changelog.

Arseniy Krasnov (3):
mtd: rawnand: nand_base: support for 'NAND_IS_BOOT_MEDIUM' flag
mtd: rawnand: meson: refactor use of 'meson_nfc_cmd_access()'
mtd: rawnand: meson: read/write access for boot ROM pages

Thank you for understanding

All the series are delegated to Neil. I will review anyway but I think
that will then pick from him

Sure I can pick them if reviewed!
