This patch places some tcpa calls into the rombios that had previously not applied anymore or were not set. Force the reads from MMIO memory locations that the compiler otherwise optimizes away (-O2) if there was an immediate write to the same memory location before. Use #define'd constants wherever possible. Fix all remaining compiler warnings. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>
