From 58507208eb1243f3ccfac36f4e9269fac35a85d0 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 14 May 2002 17:10:50 +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/bootloader/Makefile.am | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'c/src/lib/libbsp/powerpc') diff --git a/c/src/lib/libbsp/powerpc/motorola_powerpc/bootloader/Makefile.am b/c/src/lib/libbsp/powerpc/motorola_powerpc/bootloader/Makefile.am index cc7f54e074..652d4b5099 100644 --- a/c/src/lib/libbsp/powerpc/motorola_powerpc/bootloader/Makefile.am +++ b/c/src/lib/libbsp/powerpc/motorola_powerpc/bootloader/Makefile.am @@ -11,9 +11,10 @@ VPATH = @srcdir@:@srcdir@/../../shared/bootloader:@srcdir@/../../shared/console noinst_PROGRAMS = bootloader.o -bootloader_o_SOURCES = misc.c pci.c zlib.c mm.c em86.c polled_io.c lib.c +## IMPORTANT: head.S must be first, T.
