On Fedora you normally install files using yum.

i.e. yum install <packagename>
e.g. yum install rtems-4.10-powerpc-rtems4.10-gcc

Internally, in a first step yum downloads a repository's "metadata", 
i.e. e.g. the files inside of

It processes this "metadata" and then downloads the *.rpms requires to 
fullfill your "install request" (This might comprise a chain of 

In a default F12 configuration, it (temporarily) stores ("cashes" these 
files into a directory below /var/cache/yum/

In case of the rtems-4.10 repository, this would be

Anywhere you want them :)

But you'd use "yum localinstall" instead of "yum install", then

yum localinstall \
rtems-4.10-powerpc-rtems4.10-gcc-4.4.4-1.x86_64.rpm \

The details are bit more difficult :)

I guess, what you actually want is running yum with a "hot cache",
i.e. to keep the files below /var/cache/yum between yum runs and reuse 
them when needed.

The trick to achieve this is to set
in /etc/yum.conf.

With this option set, /var/cache/yum/* will fill with all packages you 
install (c.f. man 5 yum.conf).
