Actually I do think Davinci is messed up.

Many boards define CONFIG_ENV_SIZE as 256 or 128 KiB, which makes no
sense (it just slows down booting):

	davinci_dm355evm, davinci_dm355leopard, davinci_dm365evm,
	davinci_dvevm, davinci_schmoogie, davinci_sffsdr

And many boards define a ewrase block size which seems to be way too
small for common NAND flash devices:

	davinci_dvevm		512 or 2048 bytes
	davinci_schmoogie	2048 bytes
	davinci_sffsdr		2048 bytes
	davinci_sonata		512 bytes


Sandeep, can you please have a look?  Thanks in advance.


Best regards,

Wolfgang Denk
