Hi, all!
I am trying to build u-boot on sc520_cdp board. I have read all missives about sc520_cdp board, but still can’t solve my problem on HUGE size of u-boot.bin. After reading Mr. Jon Loeliger’s missive about _Why objdump Creates 4G U-Boot Images_, I know how to check the reason of u-boot. bin’s size. But after reading u-boot.lds in board/sc520_cdp/, I feel that I cannot change the mapping addresses, such as TEXT_BASE= 0x387c0000, and .bios 0 : AT ( LOADADDR(.realmode) + SIZEOF(.realmode) ) { *(.bios) }.
According to Mr. Jon Loeliger’s missive, text section’s address(0x387c0000) and .bios section’s address(around 0) result in the huge size of u-boot.bin. But I know because after start up computer it is realmode in x86, .bios section should be mapped to low address. So I feel in dilemma right now. What should I do? Guys out there who have built out u-boot.bin based on x86 successfully please help me! Detailed information will be nice.
