2012-09-17mxc nand: Let driver detect IP revisionBenoît Thébaudeau
There is no reason to have board configs to select the NFC IP revision. Just let the driver detect it. BTW, remove broken NFC IP revision configs from board config files.

2012-09-17mtd mxc nand: Fix ECC state after read_page_raw_syndrome()Benoît Thébaudeau
mxc_nand_read_page_raw_syndrome() should reenable ECC upon exit. This fixes ECC errors left uncorrected after a call to this function.

2012-09-17spl mxc nand: Fix broken boot for correctable ECC errorsBenoît Thébaudeau
Do not stop boot as soon as an ECC error is detected. Only stop boot for uncorrectable ECC errors. This fixes boards no longer booting after some time because a NAND Flash bit has flipped.

2012-09-17mxc nand: Access all ecc_status_result fieldsBenoît Thébaudeau
On the NFC IP 1.1, the 32-bit ecc_status_result value comes from 2 consecutive 16-bit registers. This patch reads all the fields of this value, which makes a difference for 4-kiB NF pages.

2012-09-17spl mxc nand: Set symmetric modeBenoît Thébaudeau
Set the spl mxc nand driver for IP 1.1 in symmetric mode, like the mtd driver. In this way, for both drivers, one input clock period of the NFC IP will produce one R/W cycle.

2012-09-17mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverMarek Vasut
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.

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.

2012-09-17mtd: support ONFI multi lun NANDMatthieu CASTET
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.

2012-09-02powerpc: re-add bi_ip_addr to bd_t structAnatolij Gustschin
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.
