The current implementation of cfi_flash uses udelay to reset watchdog.
If several blocks are blank (0xff filled) the watchdog timed out.
The reason is, udelay is never called, if flash device is ready to fast.

e.g.
     mw.w $(copy_addr) FFFF 10000;cp.b $(copy_addr) 10880000 20000

     -> watchdog timed out

     mw.w $(copy_addr) 0000 10000;cp.b $(copy_addr) 10880000 20000

     -> watchdog not timed out

This patch adds an extra watchdog reset in front of flash ready check.

This allows a driver to run code between nand_scan_ident() and
nand_scan_tail(), among other things.  See the additions to
doc/README.nand for details.

To allow a gradual transition, Boards that don't set
CONFIG_SYS_NAND_SELF_INIT will still be initialized the old way, but
new drivers should not require this, and existing drivers should be
converted when convenient.

  Date:   Thu Dec 15 10:55:37 2011 +0100

      nand_spl_simple: store ecc data on the stack

      Currently nand_spl_simple puts it's temp data at 0x10000 offset in SDRAM
      which is likely to contain already loaded data.
      The patch saves the oob data and the ecc on the stack replacing
      the fixed address in RAM.

While nand_spl is on its way out, in favor of spl, there are still
many boards using it, and conversions are gradual.  This allows us
to get rid of CONFIG_SYS_NAND_ECCSTEPS and CONFIG_SYS_NAND_ECCTOTAL now,
which would otherwise be likely to linger unreferenced after a conversion.

It also eliminates a temporary error in the hawkboard_nand build, since
the spl version of the patch removed ECCSTEPS/TOTAL from hawkboard.h, but
the spl conversion is pending (and may be merged via a different tree).

At old overo boards TWL4030 RTC irq is connected to gpio112. Unfortunately
this pin is also used for revision detection. Therefore we need to send
shut-up to TWL4030 to avoid reading wrong revision. In SPL this must
be done before SDRAM is set up because the type of SDRAM is revision dependent.
By this patch it is ensured that all variables used by omap24xx_i2c.c are
located in SRAM.
