[U-Boot] T4QDS e6500 core and U-Boot 64-bit

[Danny Gale]

Hi All,

The T4240 on the T4QDS board is a PPC e6500 core (64 bit), but it is 
configured in U-Boot as an e500 core, which is 32 bit. Why is this? Can 
it be updated to e6500?

This leads directly into another question: can U-Boot be compiled and 
run 64-bit? So far, I have been unable to make it work with a 64-bit 
compiler. I'm running into these errors:

cc1: error: -mcall not supported in this configuration
cc1: error: -mrelocatable not supported in this configuration
cc1: error: -meabi not supported in this configuration

Specifying CFLAGS="-meabi -mrelocatable -mcall-sysv" will get through 
make T4240QDS_config without errors, but the above errors show up when 
making the following targets:
 > include/autoconf.mk
 > include/autoconf.mk.dep
 > include/spl-autoconf.mk
 > include/tpl-autoconf.mk

The build then fails, with a call to cross-gcc which does not include 
the specified CFLAGS. Is this a bug in the Makefile, that CFLAGS is not 
being passed to the call to cross-gcc?

Thanks,
Danny
