[U-Boot-Users] relaxing 256MB assumption

[L.Campora at Sirti.it]

Hi all,
I need to execute U-boot in a memory region higher than 256MB.
In order to do so, I changed the piece of code in board.c (under the 
CONFIG_VERY_BIG_RAM branch)
from

--      /* only allow stack below 256M */
--      addr = CFG_SDRAM_BASE +
--             (gd->ram_size > 256 << 20) ? 256 << 20 : gd->ram_size;

to

++      /* only allow stack below 256M */
++      addr = CFG_SDRAM_BASE +
++             (gd->ram_size > CFG_MAX_DRAM_UBOOT_SIZE << 20) ? 
CFG_MAX_DRAM_UBOOT_SIZE << 20 : gd->ram_size;

where CFG_MAX_DRAM_UBOOT_SIZE is a constant that I assign to be 1GB (the 
physical dimension of my memory).

Apparently, U-boot seems to work fine.. (boots from network, programs 
flashes...)

Is there anything else I need to atke into account for my needs?

Thanks

luigi
