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

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,
