Subject: Xilinx: ARM: SCU timer input frequency update.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1dbcd31ab52bd396e1eb82074cb67eb45d14e971;p=thirdparty%2Fu-boot.git

Xilinx: ARM: SCU timer input frequency update.

Modified the 'xpele.h' configuration such that the timer input
frequency is always half of the CPU core clock frequency from
'xparameters.h' (PERIPHCLK in the TRM) instead of hard-coded
to 5 MHz.
