2012-09-18mxc nand: Fix warning on !MXC_NFC_V2_1Tom Rini
In board_nand_init() we only need the 'tmp' variable if MXC_NFC_V2_1 is defined. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-17mxc nand: Homogenize IP revisions with LinuxBenoît Thébaudeau
Use the same IP revisions as in Linux in order to make the comparison more clear. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Scott Wood <scottwood@freescale.com> Cc: Stefano Babic <sbabic@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>
2012-09-17mtd mxc nand: Merge init functionsBenoît Thébaudeau
Merge mxc_setup_config1() into board_nand_init() in order to ease the addition of i.MX5 support in the following patches.

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.

2012-09-17mtd mxc nand: Use _mxc_nand_enable_hwecc()Benoît Thébaudeau
Use _mxc_nand_enable_hwecc() instead of duplicating its code. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Cc: Scott Wood <scottwood@freescale.com> Cc: Stefano Babic <sbabic@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>
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.

2011-10-03mxc_nand: fix a problem writing more than 32MBHelmut Raiger
When writing 0x4000 to the unlockend_blkaddr register, large writes to a 2k page NAND sometimes fail. The current kernel driver writes 0xFFFF to this register for V2 of the nand controller. However on an i.MX31 this also fixes writes larger than 32MB. The datasheet is very unspecific, but (0x4000=16384)*2000 roughly fits the limits we're encountering with NAND writes. This problem might be NAND chip specific. Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Signed-off-by: Scott Wood <scottwood@freescale.com>

2010-01-19MXC: Add large page oob layout for i.MX31 NAND controller.Magnus Lilja
Import the large page oob layout from Linux mxc_nand.c driver. The CONFIG_SYS_NAND_LARGEPAGE option is used to activate the large page oob layout. Run time detection is not supported as this moment. This has been tested on the i.MX31 PDK board with a large page NAND device. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>
