Changes since v3:
- Split into multiple patches
Changes since v2:
- Fixed typo in comment for spansion_overlaid_erase()
- Fixed expressions for addr and len check in spansion_overlaid_erase()
- Added device ID check to make the changes effective for S25 only
- Added nor->setup() and fixup hooks based on the following patches https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-7-p.yad... https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-8-p.yad... https://patchwork.ozlabs.org/project/uboot/patch/20200904153500.3569-9-p.yad...
Please let me revise this series. I would like to add 2Gb (dual die package) and 4Gb (quad die package) pats support.
Thanks, Takahiro
