P2041: confusion related to "CONFIG_SYS_TEXT_BASE"

In my board, based on P2041rdb, i'm trying to understand u-boot bring-up sequence.

U-boot is flashed in NOR flash(size: 128MB), connected over eLBC-->CS0 interface.

in P2041RDB.h file, we have

CONFIG_SYS_FLASH_BASE     0xE800_0000 [ Assume we have to assign starting address of NOR flash, where first file will be residing. Here RCW we are keeping].

In another flag,

CONFIG_SYS_TEXT_BASE       0xEFF8_0000 [This is the NOR flash address where U-Boot is stored].


But i got confused what address we must assign in "CONFIG_SYS_TEXT_BASE" NOR flash address or RAM address, where u-boot should relocate while booting??
