[U-Boot] [RFC] [PATCH] arm: arm926ejs: use ELF relocations

[du zhigang]

dear:

i am using u-boot 2011.03-rc1 compiled by
CS arm-none-eabi-gcc 4.5.1

board at91sam9263ek_norflash_boot_config i
using gdb 6.8.1 debug it

when u-boot compiled  i found an error

 

/dzg/crosstool/4.5.1/bin/.arm-none-eabi-ld:
warning: creating a DT_TEXTREL in object.

 

/dzg/x86/insight-6.8-1/gdb/insight -se
u-boot

when i set breakpoint such as

b board_init_f it seems to show wrong line
number at line 132

 

i also found this version of u-boot change
board_init_f to run in flash

why dose it? in version 2010.09 it run
after relocated in ram

i found the linker link  init_fnc_t *init_sequence[]

functions with address like 0x23fxxxxx

what does the linker do with -pie option
does it link the functions run in flash with addr like 0xaxxxx?

 

do you test eldk 4.2 compiled with this
board and run in norflash?

 

thanks 

best regards
