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 diff --git a/c/src/lib/libbsp/powerpc/motorola_powerpc/console/Makefile.am b/c/src/lib/libbsp/powerpc/motorola_powerpc/console/Makefile.am index f300782dd9..a3368abc16 100644 --- a/c/src/lib/libbsp/powerpc/motorola_powerpc/console/Makefile.am +++ b/c/src/lib/libbsp/powerpc/motorola_powerpc/console/Makefile.am @@ -5,7 +5,7 @@ VPATH = @srcdir@:@srcdir@/../../shared/console:@srcdir@/../../../shared -C_FILES = polled_io.c uart.c console.c inch.c +C_FILES = polled_io.c uart.c console.c inch.c reboot.c C_O_FILES = $(C_FILES:%.c=$(ARCH)/%.o) H_FILES = ../../shared/console/consoleIo.h ../../shared/console/keyboard.h \ diff --git a/c/src/lib/libbsp/powerpc/motorola_powerpc/pci/Makefile.am b/c/src/lib/libbsp/powerpc/motorola_powerpc/pci/Makefile.am index bc37b878ab..a1f05ebce6 100644 --- a/c/src/lib/libbsp/powerpc/motorola_powerpc/pci/Makefile.am +++ b/c/src/lib/libbsp/powerpc/motorola_powerpc/pci/Makefile.am @@ -5,7 +5,7 @@ VPATH = @srcdir@:@srcdir@/../../shared/pci -C_FILES = pci.c +C_FILES = pci.c detect_raven_bridge.c pcifinddevice.c C_O_FILES = $(C_FILES:%.c=$(ARCH)/%.o) H_FILES = ../../shared/pci/pci.h |
