Hmm.. I need here this patch (for ELDK-4.2 only):

diff --git a/config.mk b/config.mk
index ddaa477..1aaf2a2 100644
--- a/config.mk
+++ b/config.mk
@@ -254,7 +254,7 @@ ifneq ($(CONFIG_SYS_TEXT_BASE),)
 LDFLAGS_u-boot += -Ttext $(CONFIG_SYS_TEXT_BASE)
 endif

-LDFLAGS_u-boot-spl += -T $(obj)u-boot-spl.lds $(LDFLAGS_FINAL)
+LDFLAGS_u-boot-spl += -N -T $(obj)u-boot-spl.lds $(LDFLAGS_FINAL)
 ifneq ($(CONFIG_SPL_TEXT_BASE),)
 LDFLAGS_u-boot-spl += -Ttext $(CONFIG_SPL_TEXT_BASE)
 endif

compiles/works with ELDK-4.2 compiles/works with ELDK-5.1 ...

a) better ideas for a fix?
b) If patch is OK, should I send for this issue in a seperate patch?

added Jason Hobbs <jason.hobbs at calxeda.com> to Cc.

Jason? Could you fix this?

Removed cmd_pxe support for the cam_enc_4xx board, as it is not needed.

Thanks!

bye,
