Hook routines

When hook routines are enabled, after one hook function call, the execution went to invalid address locations. When the it is disabled, the program works fine. When I changed to SVC mode, then also it was working fine. When analyzing, the stack used was the previous task's stack pointer.

So, when checking a function call, not only check whether the registers are properly saved and returned. But, also check the stack used is not corrupting others. Even when checking a function, check once with changing the stack pointer.

Porting MII to RMII

When RMII is added check the following:

1) CPU should have the selector bit to choose between MII and RMII. Make sure the RMII mode is selected.

2) In RMII, the MAC should be configured for Speed (10/100) and Duplex manually. Please check whether the code configures it correctly. MII may require only the Duplex to be set manually.

3) In same way as of 1), if the PHY supports both MII/RMII, the PHY should be configured for RMII. And, also check for additional settings for RMII.

4) In RMII, the 50MHz Reference clock needs to be supplied. Please check that clock supply has been enabled.

5) Finally, the GPIO settings that is subset of MII.
