[U-Boot] flash configuration in u-boot

[U-Boot] flash configuration in u-boot

[zix]

Hi, I am configuring u-boot to my board running on arm926ejs. the
flash is Nand512-A, 64Mbyte, configured on 8bit I/O bus.
page size: 512 bytes
block size: 16k

Now, in u-boot they accept in sectors, but am not having any clue how
this is related to sectors.

Can anybody please advice what values should I give for
CFG_MAX_FLASH_SECT, CFG_ENV_ADDR(considering if I have to write my env
in 2nd sector, then I need to know the sector size).....the datasheet
doesnot seem to provide information about this..actually, i am trying
to correlate between, pages, blocks and sectors as in flash data sheet
and sector size meant by uboot. And also wondering which flash driver
I should select from u-boot as my board is not listed there.

Thanks a lot,
zix
