[U-Boot] NAND booting of MPC8313 based Custom board

[Rupesh Kumar]

Hi, 
I used latest version of u-boot (U-Boot 2009.08-rc1) for NAND booting of 
my board. Still, it didn't work. 
Board starts booting and then says read failed and hangs there.  It prints 
following message on console 

"NAND boot... read failed (ltesr)"

I am using 2.1 silicon MPC8313 based custom board with large page NAND.

Can any one tell how shall i proceed for booting successfully from large 
page NAND ?

Thanks in advance
Rupesh

Please try the current upstream u-boot rather than the BSP version.  Large
page support in the mpc8313erdb BSP is likely broken.
