      ppc4xx: Big cleanup of PPC4xx defines · d1c3b275
      Stefan Roese authored 
      

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

      ppc4xx: Fix ECC Correction bug with SMC ordering for NDFC driver · 68e74567
      Feng Kan authored 
      

Fix ECC Correction bug where the byte offset location were double
flipped causing correction routine to toggle the wrong byte location
in the ECC segment. The ndfc_calculate_ecc routine change the order
of getting the ECC code.
        /* The NDFC uses Smart Media (SMC) bytes order */
        ecc_code[0] = p[2];
        ecc_code[1] = p[1];
        ecc_code[2] = p[3];
But in the Correction algorithm when calculating the byte offset
location, the s1 is used as the upper part of the address. Which
again reverse the order making the final byte offset address
location incorrect.
	byteoffs = (s1 << 0) & 0x80;
	.
	.
	byteoffs |= (s0 >> 4) & 0x08;
The order is change to read it in straight and let the correction
function to revert it to SMC order.

      Remove legacy NAND and disk on chip code. · be33b046
      Scott Wood authored 
      

Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

      ARM DaVinci: EMIF settings · d583ef51
      Thomas Lange authored 
      

NAND module should not modify EMIF registers unrelated to CS2
that is used for NAND, i.e. do not modify EWAIT config register
or registers for other Chip Selects.

Without this patch, EMIF configurations made in board_init()
will be invalidated.

      nand/mpc512x: Add MPC512x NAND support (NFC) · 35f2edbb
      Stefan Roese authored 
      

This patch adds NAND Flash Controller driver for MPC5121 revision 2.
All device features, except hardware ECC and power management, are
supported.

This NFC driver replaces the one orignally posted by John Rigby:

"[PATCH] Freescale NFC NAND driver"

It's a port of the Linux driver version posted by Piotr Ziecik a few
weeks ago. Using this driver has the following advantages (from my
point of view):

- Compatibility with the Linux NAND driver (e.g. ECC usage)
- Better code quality in general
- Resulting U-Boot image is a bit smaller (approx. 3k)
- Better to sync with newer Linux driver versions

The only disadvantage I can see, is that HW-ECC is not supported right
now. But this could be added later (e.g. port from Linux driver after
it's supported there). Using HW-ECC on the MCP5121 NFC has a general
problem because of the ECC usage in the spare area. This collides with
JFFS2 for example.

      mtd: Introduce CONFIG_MTD_DEVICE to select compilation of mtdcore.o · d558107c
      Stefan Roese authored 
      

This new define enables mtdcore.c compilation and with this we can
select the MTD device infrastructure needed for the reworked mtdparts
command.

We now have the 2 MTD infrastructure defines, CONFIG_MTD_DEVICE and
CONFIG_MTD_PARTITIONS. CONFIG_MTD_DEVICE is needed (as explained above)
for the "mtdparts" command and CONFIG_MTD_PARTITIONS is needed for UBI.

      mtd: Update MTD infrastructure to support 64bit device size · 8d2effea
      Stefan Roese authored 
      

This patch brings the U-Boot MTD infrastructure in sync with the current
Linux MTD version (2.6.30-rc3). Biggest change is the 64bit device size
support and a resync of the mtdpart.c file which has seen multiple fixes
meanwhile.
