1d5ff7e27d Blackfin arch: Fix bug - HW Errors never recover on BF548 
The kernel does not properly clear the EBIU Error Master (EBIU_ERRMST) Register
on BF548, which causes the kernel to panic.

We need to make sure that we clear the EBIU_ERRMST (necessary on BF54x)

226a6ec311 Blackfin arch: sram: use 'unsigned long' for irqflags 
Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.

The patch was generated using the Coccinelle semantic patch framework.
