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.
