Hmm.. what is your exact toolchain?

I see for the axm board:

With eldk-5.4
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot
    text    data     bss     dec     hex filename
  212583   23792   23552  259927   3f757 u-boot
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl
    text    data     bss     dec     hex filename
   14568    1212    1140   16920    4218 spl/u-boot-spl
pollux:u-boot-smartweb hs [master] $

With eldk-5.5
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot
    text    data     bss     dec     hex filename
  210690   23672   23556  257918   3ef7e u-boot
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl
    text    data     bss     dec     hex filename
   14472    1212    1140   16824    41b8 spl/u-boot-spl
pollux:u-boot-smartweb hs [master] $

for the taurus board:
eldk-5.4
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot
    text    data     bss     dec     hex filename
  284516   25500 1272228 1582244  1824a4 u-boot
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl
    text    data     bss     dec     hex filename
   14488    1212    1140   16840    41c8 spl/u-boot-spl
pollux:u-boot-smartweb hs [master] $
eldk-5.5
pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size u-boot

pollux:u-boot-smartweb hs [master] $ arm-linux-gnueabi-size spl/u-boot-spl
    text    data     bss     dec     hex filename
   14392    1212    1140   16744    4168 spl/u-boot-spl
pollux:u-boot-smartweb hs [master] $
