[U-Boot] environement paramters with u-boot in nand

Hi, I am currently working on AMCC Kilauea eval board. I am using u-boot 2009.3. I boot my board from nand. By default, when booting from nand, the environment (u-boot parameters) are embedded to u-boot. I am interested to know if it is possible to get u-boot environment parameters out of u

Re: [U-Boot] NAND bad environment block handling

My understanding is that u-boot already support bad block for the environment config. When reading or writing the config from/to the nand, u-boot skip bad block. However, you need to reserve some spare blocks in nand for environment config. This is done in u-boot-nand.lds: /* Align to next
