[U-Boot-Users] port u-boot to my custom mpc7410+gt64260 board

[张磊]

Hi all.
I want to port u-boot to my mpc7410 board.My board is very like Dy4-181 board,there are mpc7410 processor,Gt64260B bridge,512MB SDRAM,48MB flash and rtc uart so on.
I have seen every board config file about gt64260+mpc74xx,but haven't found similar board like mine.Anyone can suggest one reference board suitable for me?
My board memory map below:
SCS0                 00000000-1FFFFFFFF
PCI_0 I/O         E0000000-E0FFFFFF
PCI_0 M0         E0000000-DFFFFFFF
PCI_0 M1         40000000-41FFFFFF
PCI_0 M2         90000000-91FFFFFF
PCI_0 M3         RESERVE
PCI_1 I/O         E8000000-EFFFFFFF
PCI_1 M0         B0000000-BFFFFFFF
PCI_1 M1         C0000000-CFFFFFFF
PCI_1 M2         RESERVE
PCI_1 M3         RESERVE
Gt registers         F1000000-F100FFFF
CS0                    FD000000-FDFFFFFF flash
CS1                    FE000000-FEFFFFFF  flash
CS2                   F4000000-F4000FFF    uart rtc
CS3                    F5000000-F5007FFF    nvram
BOOTCS            FF000000-FFFFFFFF  flash
 
And I don't understand some definition in /include/config/evb64260:
#define CFG_DFL_GT_REGS		0x14000000	/* boot time GT_REGS */
#define CFG_MISC_REGION_BASE	0xf0000000            /* What to put in the bats. */
what's difference between  CFG_DFL_GT_REGS and CFG_GT_REGS?
what is CFG_MISC_REGION_BASE?

I am new to u-boot.Hope for any advice.Thank you advance.
