As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.
