Is it possible it should be as below instead?
{ INFO_STACKED("mt25qu02g", 0x20bb22, 0x1040, 64 << 10, 4096, ER_4K | ER_32K,
2) },
's/0x20ba22/0x20bb22/' (or 's/mt25qu02g/mt25ql02g/') since 'u' looks to stand
for 1.7-2.0 V and 'bb' for 1.8 V (see page 2 and 32 in [1]).
s/ER_4K/ER_4K | ER_32K/ since ERASE_32K is supported (see page 36).
If you find above changes ok and go with them please add:
