* etrax: Remove hw/etraxfs.c.Edgar E. Iglesias2011-08-092-159/+1Star
| | | | | | | | | | | | The Bare ETRAX FS board was a fictive machine that I used when developing the CRIS system emulation. Since we support the real AXIS-dev88 developer boards, there is no reason to keep the fictive one around. This commit also removes the double registration of the axis-dev88 board.

* | Check fread() results to avoid gcc 4.6 warningsDavid Gibson2011-08-051-0/+13
|/ | | | | | | | | | | | | | | When compiling with gcc 4.6, some code in fw_cfg.c complains that fop_ret is assigned but not used (which is true). However, it looks like the meaningless assignments to fop_ret were done to suppress other gcc warnings due to the fact that fread() is labelled as warn_unused_result in glibc. This patch avoids both errors, by actually checking the fread() result code and dropping out with an error message if it fails.
