2020-06-26mtd: rawnand: qcom: set BAM mode only if not set alreadySivaprakash Murugesan
BAM is DMA controller on QCOM ipq platforms, BAM mode on NAND driver is set by writing BAM_MODE_EN bit on NAND_CTRL register. NAND_CTRL is an operational register and in BAM mode operational registers are read only. So, before enabling BAM mode by writing the NAND_CTRL register, check if BAM mode was already enabled by the bootloader, and enable BAM mode only if it is not enabled already.

Instead of manipulating the statically allocated structure and copy timings around, allocate one at identification time and save it in the nand_chip structure once it has been initialized.
