Hi Bruce & Michal,
There is a fix for erasesize in dual mode in xilinx v4.19 kernel, but the
spi-nor framework
has changed in new version kernel, so I make this patch to fix it in new kernel.
Would you please help review and merge these patches to linux-yocto-dev
standard/
From: Quanyang Wang
The zcu102 and zc706 boards support qspi dual mode, and in
the dual mode, the erasesize for mtd device should be twice
as much as the erasesize for each nor flash chip.
