Atsushi Nemoto 740ebe4a54 MIPS: TXx9: Fix possible overflow in clock calculations 
Addition of -fwrapv option in 2.6.29 discloses possible overflow with
signed arithmetics.  For example, result of "a * 6 / 12" (int a =
400000000) is 200000000 without -fwrapv but -157913941 with -fwrapv.

Change some variable to unsigned to avoid such overflows.

Atsushi Nemoto d10e025f0e MIPS: TXx9: Cache fixup 
TX39/TX49 can enable/disable I/D cache at runtime.  Add kernel options
to control them.  This is useful to debug some cache-related issues,
such as aliasing or I/D coherency.  Also enable CWF bit for TX49 SoCs.
