Hi,
reading a NAND page in raw mode is required to check the consistence of the so-
called FCBs (used to boot the SoC from NAND content).
Before e5e5631cc88987a6f3cd8304660bd9190da95916 ("mtd: rawnand: gpmi: Use
nand_extract_bits()") it reads the first page of the NAND correctly as:

After applying e5e5631cc88987a6f3cd8304660bd9190da95916 reading the same page
the reported content is broken (the NAND page still contains correct data):
