Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.

"For the beagleboard, ecc.size is not explicitly set when doing 'nandecc

set to 256 bytes.
When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when
changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly
the format has changed."
No patch has been submitted and the issue was still present. This patch
adds the mentioned solution. Tested on a tam3517 board.

The DMA transfers happen only if the transfered data are larger
than 512 bytes. Otherwise PIO is used. This is a small speed
optimization.
The DMA transfer doesn't work if unaligned transfer is requested
due to the limitation of the DMA controller. This has to be fixed
by introducing generic bounce buffer. Therefore the DMA feature
is now disabled by default.

I've tested it with EEPROM (16 bit address) and TPS65217 chip

Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips
