[U-Boot] Setting CONFIG_SYS_TEXT_BASE when CONFIG_NAND_SPL is selected

Hi,
On a MX31PDK the only boot media is NAND flash, so I was trying to get rid of the conditional setting of CONFIG_SYS_TEXT_BASE.
CONFIG_NAND_SPL is set in nand_spl/board/freescale/mx31pdk/Makefile.
,so I tried the following:
diff --git a/board/freescale/mx31pdk/config.mk b/board/freescale/mx31pdk/config. index de2c642..b9932ec 100644 --- a/board/freescale/mx31pdk/config.mk +++ b/board/freescale/mx31pdk/config.mk @@ -1,5 +1,2 @@ -ifdef CONFIG_NAND_SPL CONFIG_SYS_TEXT_BASE = 0x87ec0000 -else -CONFIG_SYS_TEXT_BASE = 0x87f00000 -endif +
,but this causes the board not to boot.
Does anyone have any ideas as to why the patch above does not work?
Thanks,
Fabio Estevam

As far as I can see: it seems to me that the config.mk avoid that the u-boot image overwrites the SPL code, making then impossible to boot. Is it really copied into CONFIG_SYS_NAND_U_BOOT_DST ?
However, I see that CONFIG_SYS_TEXT_BASE_SPL is set in some boards, and looks liketo be the correct mechanims to be used to set TEXT_BASE for the SPL binary.

CONFIG_SYS_TEXT_BASE_SPL should be used for the SPL address.
