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.
