confused kernel compressed code link address

[Chuck Huang]

Dear all,

Now i am looking into kernel decompressed code, arch/arm/boot/compressed/head.S

As i objdump arch/arm/boot/compressed/vmlinux, the start section address is 0x0.

vmlinux.S
373789| Disassembly of section .text:
373790|
373791| 00000000 <start>:
373792| #endif

if the code run in 0x8000 0000(which is DDR base address), but the
link address is zero, how it works ?

best regards
