124 | Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably |
---|
125 | with the goal to make it more flexible and reusable by other |
---|
126 | BSPs. The main strategies were: |
---|
127 | - eliminate hardcoded base addresses; devices use offsets |
---|
128 | and a BSP defined base address. |
---|
129 | - separate functionality into different files (e.g. reboot from |
---|
130 | inch.c to reboot.c) which can be overridden by a 'derived' BSP. |
---|
131 | - separate initialization code into separate files (e.g. PCI |
---|
132 | bridge detection/initialization was separated from the more |
---|
133 | generic PCI access routines), also to make it easier for |
---|
134 | 'derived' BSPs to substitute their own initialization code. |
---|
135 | There are also a couple of enhancements and fixes: |
---|
136 | - IRQ handling code now has a hook for attaching a VME bridge. |
---|
137 | - OpenPIC is now explicitely initialized (polarities, senses). |
---|
138 | Eliminated the implicit assumption on the presence of an ISA PIC. |
---|
139 | - UART and console driver now supports more than 1 port. The current |
---|
140 | maximum of 2 can easily be extended by enlarging a table (it |
---|
141 | would even be easier if the ISR API was not broken by design). |
---|
142 | - fixed polled_io.c so it correctly supports console on COM2 |
---|
143 | - fixed TLB invalidation code (start.S). |
---|
144 | - exception handler prints a stack backtrace. |
---|
145 | - added BSP_pciFindDevice() to scan the pci bus for a particular |
---|
146 | vendor/device/instance. |

152 | .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*. Spacing corrections |
---|
153 | and direction of segments to memory regions may also have been |
---|
154 | addressed. This was a sweep across all BSPs. |
