Hi:

I'm developing a board based on MPC8541,the memory map of the board is like this:

0xfff80000 0xffffffff TLB1_5 Boot Rom 512KB SST39VF 0xff700000 0xff7fffff TLB1_1 CCSR 1MB 0xff680000 0xff6fffff TLB1_8 NvRAM 512KB(128KB) 0xff600000 0xff67ffff TLB1_8 CPLD 512KB 0xF4000000 0xf7ffffff TLB1_6 Image Flash 64MB Intel 28f 0xf0000000 0xf3ffffff TLB1_7 Extend Flash 64MB NAND 0x00000000 0x0fffffff TLB1_3 DDR Bank1 256MB 0x10000000 0x1fffffff TLB1_4 DDR Bank0 256MB 0x20000000 0x2003ffff TLB1_2 L2 SRAM 256K 0x80000000 0x8fffffff TLB1_9 PCI0 256M 0x90000000 0x9fffffff TLB1_10 PCI0 256M

The board has two GE port on TSEC using BCM5461S,two serial port on UART using SP3232. How can I porting the u-boot to fit my board?

I have completed the first stage by this: 1.Add MYBOARD_config option to the top level of u-boot. 2.cp board/cds/mpc8541cds/* board/cds/MYBOARD/ 3.rename mpc8541cds.c to MYBOARD.c and replace "mpc8641cds" with "MYBOARD" in some files 4.cp include/configs/mpc8541cds.h MYBOARD.h 5.make MYBOARD_config,make, 6.It success build, of course not work on the target.

I know that I must custom the files below MYBORD dir, but any others? especially the UART ,BootRom and flash drivers. I find some messages about BCM5461S driver in the mail list,how can I get it?

I'm newer of using u-boot.Any help will be appreciated
