PATCH 1/1 sh: Add SH2A CodeSourcery external toolchain

Hello,

Quoted 2 lines · On Fri, 06 May 2011 15:23:04 +0100 Phil Edworthy <[email protected]>…

Added the CodeSourcery uCLinux/uClibc toolchain for the SH2A big endian devices.

Acked-by Thomas Petazzoni <[email protected]>

However, I have a question regarding the sh2a_nofpueb and sh2eb target architecture variants to which this toolchain applies. In Buildroot, we use the target architecture variant to build the host tuple, which is then used as the --host=XXX-YYY argument to build autotools-based packages.

So for example, when sh2eb is selected, we pass "--host=sh2eb-linux" to the ./configure script of all autotools-based packages.

Unfortunately, neither sh2a_nofpueb nor sh2eb are recognized as correct machine types by config.sub. From packages/gnuconfig/config.sub:

        | sh | sh[1234] | sh[24]a | sh[24]aeb | sh[23]e | sh[34]eb | sheb | shbe | shle | sh[1234]le | sh3ele \
        | sh64 | sh64le \

So, a package such as dropbear fails to build with:

checking host system type... Invalid configuration sh2eb-linux': machine sh2eb' not recognized

I don't know anything about the various CPU types in the SuperH world, so I can't fix it myself, but obviously the target variants do need some cleanup/improvements. Could you help us to improve this ?

Thanks!

Thomas

Ah, I see. I just checked busybox built for sh2a.

Hmm, SuperH has a lengthy mix of cpu types & pretty much everything I have done is with sh4a devices. I'll ask around to find out a bit more about sh2 devices and attempt to clean this up.

Thanks for pointing this out!
