* mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverMarek Vasut2012-09-17-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is based on Linux kernel -next: commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b Author: Brian Norris <computersforpeace@gmail.com> Date: Fri Jul 13 09:28:24 2012 -0700 mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

* nand: Make NAND lock status compatible with MicronJoe Hershberger2012-09-17-4/+7
| | | | | | | | | | Micron NAND flash (e.g. MT29F4G08ABADAH4) BLOCK LOCK READ STATUS is not the same as others. Instead of bit 1 being lock, it is #lock_tight. To make the driver support either format, ignore bit 1 and use only bit 0 and bit 2. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

* mtd: support ONFI multi lun NANDMatthieu CASTET2012-09-17-1/+2
| | | | | | | | | | | | | | | | | | | | | | | With onfi a flash is organized into one or more logical units (LUNs). A logical unit (LUN) is the minimum unit that can independently execute commands and report status. Mtd does not exploit LUN, so make it see a big single flash where size is lun_size * number_of_lun. Without this patch MT29F8G08ADBDAH4 size is 512MiB instead of 1GiB. Artem: split long line on 2 shorter ones.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 50a47d0523e8efebe912bef539a77ffd42116451 (net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels is broken due to changed offsets of the fields in struct bd_t. Offsets of the fields after removed bi_ip_addr are wrong, causing wrong bus clocks and console baudrate configurations and various other issues. Re-add the bi_ip_addr field to preserve backward compatibility with older ppc kernels. Setting bi_ip_addr in board.c is not really needed, grepping in the 2.4 linux tree shows that bi_ip_addr is not accessed there. Adding bi_ip_addr to struct bd_t for other arches isn't needed it seems. bd_t is not used by other arches in the 2.4 linux tree.
