FreeBSD normally links the first PT_LOAD header to 12178171Simp# begin at offset 0. 13178171Simp# 14178171Simp# * Broadcom's support package for the internal bus, the Sonics 15178171Simp# SiliconBackplane, needs to be integrated to detect and probe hardware 16178171Simp# correctly. 17178171Simp# 18178171Simp# * The clock needs to be calibrated correctly, so that DELAY() may work. 19178171Simp# One problem with this is that the low-level printf() routine calls DELAY(), 20178171Simp# which currently causes divide-by-zero trap 21178171Simp# 22178171Simp# * The Broadcom CPUs have no FPU. Attempting to detect one by reading CP1's 23178171Simp# status register causes an unhandled boot-time exception. An FPU emulator 24178171Simp# will be necessary to support multi-user boot. 25178171Simp# 26178171Simp 27178171Simpident SENTRY5 28178171Simpcpu CPU_MIPS4KC 29178171Simpoptions ISA_MIPS32 30202034Simpoptions CPU_SENTRY5 # XXX should this be a 31178171Simp # sub-cpu option? 32178171Simp 33178171Simp# XXX only siba should be hardwired for now; we will use 34178171Simp# bus enumeration there 35182738Sobrienfiles "../sentry5/files.sentry5" 36178171Simphints "SENTRY5.hints" 37178171Simp 38178171Simp# sentry5 normally ships with cfe firmware; use the console for now 39202034Simpoptions CFE 40202034Simpoptions CFE_CONSOLE 41202034Simpoptions ALT_BREAK_TO_DEBUGGER 42178171Simp 43178171Simp#makeoptions ARCH_FLAGS=-march=mips32 44178171Simpmakeoptions MIPS_LITTLE_ENDIAN=defined 45178171Simpmakeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols 46178171Simpmakeoptions MODULES_OVERRIDE="" 47178171Simp 48202034Simpoptions DDB 49202034Simpoptions KDB 50178171Simp 51202034Simpoptions SCHED_4BSD #4BSD scheduler 52202034Simpoptions INET #InterNETworking 53202034Simpoptions NFSCLIENT #Network Filesystem Client 54202034Simpoptions NFS_ROOT #NFS usable as /, requires NFSCLIENT 55202034Simpoptions PSEUDOFS #Pseudo-filesystem framework 56202034Simpoptions _KPOSIX_PRIORITY_SCHEDULING #Posix P1003_1B real-time extensions 57178171Simp 58178171Simp# Debugging for use in -current 59203938Sattilio#options DEADLKRES 60202034Simpoptions INVARIANTS 61202034Simpoptions INVARIANT_SUPPORT 62178171Simp 63202034Simp#options BUS_DEBUG 64178171Simp#makeoptions BUS_DEBUG 65178171Simp 66178171Simpdevice siba # Sonics SiliconBackplane 67178171Simpdevice pci # siba_pcib 68178171Simp 69202034Simp# device bfe # XXX will build both pci and siba 70202034Simp# device miibus # attachments 71178171Simp 72178171Simp# pci devices 73178171Simp# notyet: 74178171Simp#device ath # in pci slot 75185522Ssam#device ath_hal # pci chip support 76202034Simp#options AH_SUPPORT_AR5416 # enable AR5416 tx/rx descriptors 77178171Simp 78178171Simpdevice usb # USB Bus (required) 79178171Simpdevice uhci # UHCI PCI->USB interface 80178171Simpdevice ehci # EHCI PCI->USB interface (USB 2.0) 81178171Simp 82178171Simp# need to teach the code to ignore the bridge.... 83178171Simp 84178171Simp 85178171Simp# XXX notyet; need to be auto probed children of siba_cc. 86178171Simp#device uart 87178171Simp 88178171Simpdevice loop 89178171Simpdevice ether 90178171Simpdevice md 91
