In EBI2, all codeword data will be read in FLASH_BUF_ACC buffer and ADM will copy the data from source (FLASH_BUF_ACC) to destination (memory for data read). In QPIC, there is no FLASH_BUF_ACC and all the codeword data will held in QPIC BAM FIFO buffers. It provides multiple READ_LOCATION registers which will be used for copying the data from FIFO to memory. The READ_LOCATION register will be used to read a specific amount of data from a specific offset within the flash buffer. It supports sequential offset requests. Each request is composed of the following fields: a. Offset within the flash buffer from which data should be read b. Amount of data to be read c. Flag bit specifying the last read request from the flash buffer. Following the last read request the NANDc refers to the buffer as empty.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
