Reading less than page size from NAND ok?

[Ricard Wanderlof]

In the NAND boot code for U-Boot 1.4.4 (which use MTD (albeit an old 
version)), there is a note that when reading from NAND flash via the mtd 
layer (i.e. eventually ending up in nand_do_read_ecc()), one should start 
reading on a page boundary and read at least one page of data, in order to 
get proper ECC behavior.

However, when looking at the latest mtd code, it appears that this no 
longer is the case - when reading bursts of data less than one page, the 
data is internally buffered and a complete page read so that ECC is always 
applied properly. Is this in fact the case, or have I missed something 
vital here? (Was there such a limitation once?)
