From 25f815f66a141436df8a4c45e5d2765272aea2ac Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 30 Nov 2017 18:01:30 +0100 Subject: [PATCH] mtd: nand: force drivers to explicitly send READ/PROG commands The core currently send the READ0 and SEQIN+PAGEPROG commands in nand_do_read/write_ops(). This is inconsistent with ->read/write_oob[_raw]() hooks behavior which are expected to send these commands. There's already a flag (NAND_ECC_CUSTOM_PAGE_ACCESS) to inform the core that a specific controller wants to send the READ/SEQIN+PAGEPROG commands on its own, but it's an opt-in flag, and existing drivers are unlikely to be updated to pass it. Moreover, some controllers cannot dissociate the READ/PAGEPROG commands from the associated data transfer and ECC engine activation, and developers have to hack things in their ->cmdfunc() implementation to handle such complex cases, or have to accept the perf penalty of sending twice the same command. To address this problem we are planning on adding a new interface which is passed all information about a NAND operation (including the amount of data to transfer) and replacing all calls to ->cmdfunc() to calls to this new ->exec_op() hook. But, in order to do that, we need to have all ->cmdfunc() calls placed near their associated ->read/write_buf/byte() calls. Modify the core and relevant drivers to make NAND_ECC_CUSTOM_PAGE_ACCESS the default case, and remove this flag.
