<DIV>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.</DIV>
<DIV>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?</DIV>
<DIV>
<DIV>My board memory map below:</DIV>
<DIV>SCS0 00000000-1FFFFFFFF</DIV>
<DIV>PCI_0 I/O E0000000-E0FFFFFF</DIV>
<DIV>PCI_0 M0 E0000000-DFFFFFFF</DIV>
<DIV>PCI_0 M1 40000000-41FFFFFF</DIV>
<DIV>PCI_0 M2 90000000-91FFFFFF</DIV>
<DIV>PCI_0 M3 RESERVE</DIV>
<DIV>PCI_1 I/O E8000000-EFFFFFFF</DIV>
<DIV>PCI_1 M0 B0000000-BFFFFFFF</DIV>
<DIV>PCI_1 M1 C0000000-CFFFFFFF</DIV>
<DIV>PCI_1 M2 RESERVE</DIV>
<DIV>PCI_1 M3 RESERVE</DIV>
<DIV>Gt registers F1000000-F100FFFF</DIV>
<DIV>CS0 FD000000-FDFFFFFF flash</DIV>
<DIV>CS1 FE000000-FEFFFFFF flash</DIV>
<DIV>CS2 F4000000-F4000FFF uart rtc</DIV>
<DIV>CS3 F5000000-F5007FFF nvram</DIV>
<DIV>BOOTCS FF000000-FFFFFFFF flash</DIV>
<DIV> </DIV></DIV>
<DIV>And I don't understand some definition in /include/config/evb64260:</DIV>
<DIV>#define CFG_DFL_GT_REGS 0x14000000 /* boot time GT_REGS */<BR>#define CFG_MISC_REGION_BASE 0xf0000000 /* What to put in the bats. */<BR>what's difference between CFG_DFL_GT_REGS and CFG_GT_REGS?</DIV>
<DIV>what is CFG_MISC_REGION_BASE?</DIV>
<DIV> </DIV>
<DIV>I am new to u-boot.Hope for any advice.Thank you advance.<BR><BR></DIV></div><br>
