[U-Boot] mtd: nand: oob data structures taking up a lot of space

[Aaron Williams]

Hi all,

I am working on trying to shrink down a bootloader for one of our chips 
where the bootloader must fit in around 448K of memory and things are 
fairly tight. I found that the oob data structures for 8, 16, 64 and 128 
bytes were taking up a fair amount of space. I had to increase the 
eccpos size to 640 to match the Linux kernel since the existing size was 
too small for some of the NAND devices we are working with. This caused 
each oob data structure to consume around 2.5K in the binary. By 
initializing the layout data structures at runtime I was able to 
eliminate most of the space taken since now the linker can place these 
in BSS.
