Md Sadre Alam 4a7b64ba0c mtd: rawnand: qcom: Fix last codeword read in qcom_param_page_type_exec() ... [ Upstream commit 47bddabbf6 ] For QPIC V2 onwards there is a separate register to read last code word "QPIC_NAND_READ_LOCATION_LAST_CW_n". qcom_param_page_type_exec() is used to read only one code word If it configures the number of code words to 1 in QPIC_NAND_DEV0_CFG0 register then QPIC controller thinks its reading the last code word, since we are having separate register to read the last code word, we have to configure "QPIC_NAND_READ_LOCATION_LAST_CW_n" register to fetch data from QPIC buffer to system memory. Without this change page read was failing with timeout error / # hexdump -C /dev/mtd1 [ 129.206113] qcom-nandc 1cc8000.nand-controller: failure to read page/oob hexdump: /dev/mtd1: Connection timed out This issue only seen on SDX targets since SDX target used QPICv2. But same working on IPQ targets since IPQ used QPICv1.
