Your choice though the file looks to me to be linux
specific as it uses #include <linux/stddef.h>
Also, two functions, __TBIDataCacheFlush and
__TBICodeCacheFlush, have an unnecessary indentation
level after a test and return.
void __TBICodeCacheFlush( const void *pStart, int Bytes )
{
volatile int *pCtrl = (volatile int *) SYSC_CACHE_MMU_CONFIG;
if ( !__TBICacheDoneInit )
__TBICacheInit();
if ( (pCtrl[0] & SYSC_CMMUCFG_IC_ON_BIT) == 0 )
{
/* No need to flush the code cache it's not actually enabled */
return;
}
{
/* Use a sequence of writes to flush the cache region requested */
int Loops, Step;
etc.
I believe the automatics in the second blocks should
be moved to the start of the function and the
unnecessary braces and extra indentation removed.
