[U-Boot] toolchains toolchains toolchains

[Mike Frysinger]

if you're like me, getting toolchains known to work has always been 
problematic for the arches you don't care about.  yes, there's the ELDK, but 
that doesn't cover all the arches that u-boot supports, and imo, they're 
"fatter" than necessary.

to that end, i've started posting toolchain builds here:
	http://dev.gentoo.org/~vapier/u-boot/
~5MiB d/l is nice :)

when possible, i built them which means they're recent: binutils-2.21.1 and 
gcc-4.6.2.  they were also built on an older glibc (2.4), so they should be 
usable on quite a lot of recent (and not so recent) systems.  and i've 
statically linked in all the 3rd party libraries to avoid cross-distro issues 
(mpfr/gmp/mpc/etc...).

is there interest/possibility of posting these to denx ftp and then putting 
the URL into the wiki/README ?  or perhaps the MAKEALL script when it can't 
find a usable toolchain ...

Just curious, but have you tried crosstool-ng?
If you have and had problems with it, I would be happy to help.

Crosstool-ng also has static toolchain support.

i don't need it as Gentoo provides everything for building cross-compilers

static linking glibc isn't good

nice but MAKEALL mips throws warnings for each board

/data/development/vapier-toolchains/mips-gentoo-linux-gnu/bin/mips-gentoo-linux-gnu-ld:

For current upstream MIPS support in U-Boot the toolchain should be 
built completely with soft-float.

Best regards,

thx, i wasn't sure about that.  i posted a softfloat one.
