Hello,

As promised newly compiled object files are available here
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-modules/sdcore/.
Please note the OABI object file is typically used when building TS-7xxx
kernels for Linux other than the TS-7800. The EABI object file is
typically used for compiling TS-7800 kernels, and the PECOFF object file
is typically used for WinCE. Also as promised a patch to the Makefile is
below to build a SD card driver for the TS-7800.

Don't forget to also modify your TS-7800 .config file.

And finally don't forget to download the
library(ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-modules/sdcore/EABI/tssdcore2.o)
and the header
file(ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-modules/sdcore/sdcore.h)
and put them in drivers/mmc/.
Let me know if anyone has any problems or questions on any of the
information above...
