this parameter needs to be adopted by SoC/board tester.

In short words, adopt that line to your needs:

--->8---
+	bss_mirror = (uint32_t*)(CONFIG_SYS_SDRAM_BASE + 0x600000);
---8<---

The tester have to place the 'bss_mirror' space to an appropriate value.
at91rm9200ek does have 32MiB of SDRAM, the topmost part is always used
for stack, GD, u-boot after relocation a.s.o. I usually use the RAMBOOT
configuration of at91rm9200ek. In that case TEXT_BASE is SDRAM_BASE +
0x100000. Therefore I use here 0x600000 (u-boot size plus safety).
I can not recommend a proper place for all boards cause this parameter
is highly is board specific.
