Subject: [OpenWrt-Devel] [RFC][PATCH] ath79-tiny: enable 4k sectors
This enables using 4kiB sectors as erase blocks for 4MiB NOR flash
ICs
that support it.
Writeable jffs2 overlay used to store settings requires a partition
with
at least 5 erase blocks, so using small sectors is essential for
devices
with 4MiB flash.
Sysupgrading a device running firmware without this feature will
likely
not allow to preserve configs automatically but since ath79 is
considered to be in a "technology preview" state it shouldn't be a
problem.
Because of this reason, we should ask ourselves whether we want to
backport this to 19.07, so all (non-RC) released ath79-tiny images
have 4k sectors, while we still can.
Otherwise, with 20.xx having different sectors than 19.xx, users will
be more confused than with us now changing behavior during rc-period.
As a non-voting small time contributor I'd say: yes to pushing it to
19.07 now. People are already being encouraged not to keep settings
migrating from pre-19.07 ar71xx to 19.07 ath79, so two birds with one
stone.
Cheers
Stijn
Best
Adrian
