Looked at my "museum". At least 5 pcs of sparc32 boxes but I guess the NVRAM needs repair on all of them. I have a LEON4 board somewhere on the shelf too. None of this powered up for years either - but I cannot make myself getting rid of it. Because maybe one day I find time... All that said - I have also once suggested to drop sun4m support, keeping only the LEON parts. Back then there was some resistance, but all for sentimental reasons and I can relate to that, since I kept the sparc32 boxes around. > > You could also kill the EX2 define while touchign the file, > > it is no longer used after ab5e8b331244. > > Er? No EX2 in checksum_32.S...

Somehow the grep output tricked me. Sam
