Looking at arm-errors.tar.gz -> omap2420h4.ERR
common/libcommon.a(env_flash.o): In function `env_init': /.automount/castor-vlab/root/home/wd/git/u-boot/work/common/env_flash.c:265: undefined reference to `flash_probe' make: *** [/work/wd/tmp/u-boot-arm/u-boot] Error 1
is because in board/omap2420h4 file flash.c isn't used any more. This file contains flash_probe(), but it isn't compiled. If enabled for test, there are tons of link conflicts with cfi_flash.c.
So looks to me that omap2420h4 switch to cfi disabled flash.c (and didn't remove it) but missed to resolve flash_probe() call in env_flash.c.

Proposal to fix this is to remove unused file board/omap2420h4/flash.c and remove calls of flash_probe()/omap2420h4 #ifdefs in env_flash.c. However, not sure if this is correct.
Opinions?
Cheers
