Hi all,
I am using relocation fixed a320evb (arm) u-boot.
I noticed something weird about the output of command flinfo.
The size of u-boot.bin is 129156 (0x1F884), but the protected range is only 0 ~ 0x1bfff.
I guess that it is because u-boot protects _start ~ __bss_start, but there are some other things in u-boot.bin after __bss_start, e.g. .rel.dyn section and .dynsym section
That is quite strange. According to arch/arm/cpu/arm920t/u-boot.lds, .rel.dyn and .dynsym sections should be placed before __bss_start. However, objdump shows that they are not at where they should be.
Do I understand correctly? Does anybody have similar situation?
BTW, the toolchain I am using is arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2010q1-202) 4.4.1.
