NAND FSL elbc: Use virt_to_phys to determine which bank is in use

2008-12-20T00:20:08+00:00

The current code that determines which bank/chipselect is used for a
given NAND instance only worked for 32-bit addresses and assumed
a 1:1 mapping.  This breaks in 36-bit physical configs.

The proper way to handle this is to use the virt_to_phys() and
BR_PHYS_ADDR() routinues to match the 34-bit lbc bus address
with the the virtual address the NAND code uses.

NAND: Mark the BBT as scanned prior to calling scan_bbt.

2008-12-16T20:40:34+00:00

Otherwise, recursion can occur if scan_bbt does not find a bad block
table, and tries to write one, and the attempt to erase the BBT area
causes a bad block check.

NAND: Fix misplaced return statement in nand_{read,write}_skip_bad().

2008-11-25T16:47:02+00:00

This caused the operation to be needlessly repeated if there were
no bad blocks and no errors.

NAND: Properly create JFFS2 cleanmarkers.

2008-10-29T19:20:26+00:00

As reported by Ilko Iliev , the "nand erase clean"
command is currently broken, and among other things causes all blocks
to be marked bad.

This implements it properly using MTD_OOB_AUTO, along with some
indentation fixes.

NAND fsl elbc: Set FMR[ECCM] based on page size.

2008-10-29T18:42:41+00:00

Hardware expects ECCM 0 for small page and ECCM 1 for large page
when booting from NAND, so use those defaults.

Make Freescale local bus registers available for both 83xx and 85xx.

2008-10-29T16:12:53+00:00

- Rename lbus83xx_t to fsl_lbus_t and move it to asm/fsl_lbc.h so that it
  can be shared by both 83xx and 85xx
- Remove lbus83xx_t and replace it with fsl_lbus_t in all 83xx boards
  files which use lbus83xx_t.
- Move FMR, FIR, FCR, FPAR, LTESR from mpc83xx.h to asm/fsl_lbc.h so that
  85xx can share them.

NAND: Reset chip on power-up

2008-10-29T15:42:17+00:00

Some chips require a RESET after power-up (e.g. Micron MT29FxGxxxxx).
The first command sent is NAND_CMD_READID.
Issue a NAND_CMD_RESET in nand_scan_ident before reading the device id.
Tested with an MT29F4G08AAC.

NAND: sync with 2.6.27

2008-10-29T15:42:16+00:00

This brings the core NAND code up to date with the Linux kernel.

Since there were several drivers in Linux as of the last update that are
not in u-boot, I'm not bringing over new drivers that have been added
since in the absence of an interested party.

I did not update OneNAND since it was recently synced by Kyungmin Park,
and I'm not sure exactly what the common ancestor is.
