[Richard Retanubun]

Greetings,

I am trying to x86 cross-compile u-boot 2009.03-rc2 for the MCF5270 with gcc 4.3.3 and binutils 2.19.1 results in a u-boot that
fails its relocation to RAM. My boot sequence is this

U-Boot 2009.03-rc2dvl-00030-g28b1dbe (Mar 19 2009 - 10:21:06)

CPU:   Freescale ColdFire MCF5270 rev. 1, at 150 MHz

Out:   serial
Err:   serial

Hit any key to stop autoboot:  0

My gcc-4.3.3 compile flags are:

Things of note
1. /cpu/mcf52x2/config.mk: the pre gcc-4.2.x, the cpu type is -m5307 and now it is -mcpu=5271
2. If I do objdump -d on the ELF, the newer toolchain seems to align code on 16-bit boundary, while the old one align code on 32-bit boundary.
3. With gcc-4.3.3. if I enforce -m5307, I got an error:
    start.S:144: Error: operands mismatch -- statement `movec %d0,%RAMBAR1' ignored
    Faking RAMBAR1 to RAMBAR bypasses this error, but the resulting binary won't boot (e.g. no single printf is printed after a reset).

Questions:
1. What am I missing?
2. What are the recommended tool-chain for building M5270 coldfire for u-boot?

Thanks very much for your time,
