[ELDK] whether eldk 5.5.3 support 64bit cross compilation for powerpc e6500 core?

[karunakaran.krishnan]

Hi Wolfgang Denk,

Thanks for your information.

Eldk5.5.3 e500v2 cross compiler has been installed on my 
fedora20(x86_64) host PC.

I wants to compile u-boot in 32bit mode(with Utilizing 36bit physical 
Addressing) and
linux in 64bit mode for the e6500 core(T2080 processor).

U-boot-2014.10 has been compiled sucessfully in eldk5.5.3 e500v2 cross 
compiler with the following environmental variable.
ARCH="powerpc"
CROSS_COMPILE="powerpc-linux-gnuspe-"
CC="powerpc-linux-gnuspe-gcc  -m32 -mcpu=8548 -mabi=spe -mspe 
-mfloat-gprs=double
  
--sysroot=/opt/eldk-5.5.3/powerpc-e500v2/sysroots/ppce500v2-linux-gnuspe"

As, I assumed that -m32 flag refers to 32bit compilation mode.

I have been unable to compile the linux in 64bit by changing the flag as 
-m64.

Kindly suggest me, How to compile the linux in 64bit mode for e6500 
based core?
