[U-Boot-Users] Flash adress, memory ??

[Bruce]

Hi!

I am trying to port u-boot for a MEMEC xc2vp20 board, Xilinx virtex II
Pro and PPC405. I have some difficulties. I have already read README
file but i didn"t understand everything.


1) Is it true that we can't (or difficult) to put u-boot in SDRAM? 

2) What represent CFG_ENV ?

3) If I want to put u-boot on a FLASH memory, i need to use
CFG_ENV_FLASH, but what adress to put?
In fact, in my project, to declare the flash memory, I have this information:

Flash 1Mx32
 C_BASEADDR: 0x82003000
 C_HIGHADDR : 0x820031FF
 C_MEM0_BASEADDR: 0x83600000
 C_MEM0_HIGHADDR : 0x836FFFFF
 C_MEM0_BASEADDR: 0x84000000
 C_MEM0_HIGHADDR : 0x843FFFFF

FLASH_RESET
 C_BASEADDR: 0x82004000
 C_HIGHADDR : 0x820041FF

FLASH_READY
 C_BASEADDR: 0x82005000
 C_HIGHADDR : 0x820051FF


Thanks,
