4 | * console/polled_io.c: libcpu provides 'printk' already. |
---|
5 | Therefore, the implementation in this file was removed (still |
---|
6 | used for the bootloader, though). It now provides BSP_output_char() |

7 | for libcpu's printk(). |
---|
8 | * console/uart.c, console/uart.h: BSP_output_char_via_serial() |
---|
9 | prototype changed to match the BSP_output_char_function_type. Note |
---|
10 | that the motorola BSPs use polled-io for the output_char routine, not |

11 | the uart.c version. The latter can be used be other BSPs however |

150 | Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably |
---|
151 | with the goal to make it more flexible and reusable by other |
---|
152 | BSPs. The main strategies were: |
---|
153 | - eliminate hardcoded base addresses; devices use offsets |
---|
154 | and a BSP defined base address. |
---|
155 | - separate functionality into different files (e.g. reboot from |
---|
156 | inch.c to reboot.c) which can be overridden by a 'derived' BSP. |
---|
157 | - separate initialization code into separate files (e.g. PCI |
---|
158 | bridge detection/initialization was separated from the more |
---|
159 | generic PCI access routines), also to make it easier for |
---|
160 | 'derived' BSPs to substitute their own initialization code. |
---|
161 | There are also a couple of enhancements and fixes: |
---|
162 | - IRQ handling code now has a hook for attaching a VME bridge. |
---|
163 | - OpenPIC is now explicitely initialized (polarities, senses). |
---|
164 | Eliminated the implicit assumption on the presence of an ISA PIC. |
---|
165 | - UART and console driver now supports more than 1 port. The current |
---|
166 | maximum of 2 can easily be extended by enlarging a table (it |
---|
167 | would even be easier if the ISR API was not broken by design). |
---|
168 | - fixed polled_io.c so it correctly supports console on COM2 |
---|
169 | - fixed TLB invalidation code (start.S). |
---|
170 | - exception handler prints a stack backtrace. |
---|
171 | - added BSP_pciFindDevice() to scan the pci bus for a particular |
---|
172 | vendor/device/instance. |

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