should stop anyone from converting...), but it will with the in-progress
hack to support 4k-page NAND.

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.

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.

In commit 06194b6b65 a separate header

Before this commit, the da850evm.h configuration file was used for both
the AM1808 and the OMAP-L138 EVMs. The only substantial difference
between the da850evm and the da850_am18xxevm configuration is a single
bit in the hardware revision that is passed to the Linux kernel.
This patch removes include/configs/da850_am18xxevm.h. Instead the
include/configs/da850evm.h configuration is used for AM18xx EVMs and
CONFIG_DA850_AM18X_EVM is defined in boards.cfg.
