From 6a4df9f918ee72b73a7da49068e3551ecb80803e Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 14 May 2002 17:10:49 +0000 Subject: 2001-05-14 Till Straumann * bootloader/Makefile.am, console/Makefile.am, pci/Makefile.am: Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably with the goal to make it more flexible and reusable by other BSPs. The main strategies were: - eliminate hardcoded base addresses; devices use offsets and a BSP defined base address. - separate functionality into different files (e.g. reboot from inch.c to reboot.c) which can be overridden by a 'derived' BSP. - separate initialization code into separate files (e.g. PCI bridge detection/initialization was separated from the more generic PCI access routines), also to make it easier for 'derived' BSPs to substitute their own initialization code. There are also a couple of enhancements and fixes: - IRQ handling code now has a hook for attaching a VME bridge. - OpenPIC is now explicitely initialized (polarities, senses). Eliminated the implicit assumption on the presence of an ISA PIC. - UART and console driver now supports more than 1 port. The current maximum of 2 can easily be extended by enlarging a table (it would even be easier if the ISR API was not broken by design). - fixed polled_io.c so it correctly supports console on COM2 - fixed TLB invalidation code (start.S). - exception handler prints a stack backtrace. - added BSP_pciFindDevice() to scan the pci bus for a particular vendor/device/instance. --- c/src/lib/libbsp/powerpc/motorola_powerpc/ChangeLog | 17 +++++++++++++++++ .../libbsp/powerpc/motorola_powerpc/console/Makefile.am | 2 +- .../lib/libbsp/powerpc/motorola_powerpc/pci/Makefile.am | 2 +- 3 files changed, 19 insertions(+), 2 deletions(-) (limited to 'c/src/lib') diff --git a/c/src/lib/libbsp/powerpc/motorola_powerpc/ChangeLog b/c/src/lib/libbsp/powerpc/motorola_powerpc/ChangeLog index 33d57d5652..aba0be1e6e 100644 --- a/c/src/lib/libbsp/powerpc/motorola_powerpc/ChangeLog +++ b/c/src/lib/libbsp/powerpc/motorola_powerpc/ChangeLog @@ -1,3 +1,20 @@ +2001-05-14 Till Straumann + + * bootloader/Makefile.am, console/Makefile.am, pci/Makefile.am: + Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably + with the goal to make it more flexible and reusable by other + BSPs.
