So far there is no need for a clock driver in U-Boot because the previous boot stage leaves all the necessary clocks on. However, some drivers in U-Boot (e.g. arm_pl180_mmci) depend on having a clock driver to obtain the clock frequency. Setting up the clock drivers properly is a bit tricky on U8500, so for now add a simple fixed-clock for the eMMC that allows obtaining the clock frequency. This should be replaced eventually if some board actually requires enabling some of the clocks. Signed-off-by: Stephan Gerhold <stephan@gerhold.net>
