Missed in merge of PR213. 2001-05-14 Till Straumann * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add the following: - support for the MPC74000 (AKA G4); there is no AltiVec support yet, however. - the cache flushing assembly code uses hardware-flush on the G4. Also, a couple of hardcoded numerical values were replaced by more readable symbolic constants. - extended interrupt-disabled code section so enclose the entire cache flush/invalidate procedure (as recommended by the book). This is not (latency) critical as it is only used by init code but prevents possible corruption. - Trivial page table support as been added. (1:1 effective-virtual-physical address mapping which is only useful only on CPUs which feature hardware TLB replacement, e.g. >604. This allows for write-protecting memory regions, e.g. text/ro-data which makes catching corruptors a lot easier. It also frees one DBAT/IBAT and gives more flexibility for setting up address maps : -) - setdbat() allows changing BAT0 also (since the BSP may use a page table, BAT0 could be available...). - asm_setdbatX() violated the SVR ABI by using r20 as a scratch register; changed for r0 - according to the book, a context synchronizing instruction is necessary prior to and after changing a DBAT -> isync added * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating point context. The fpsave and fprestore routines are only used in a executing context which _is_ fp and hence has the FPU enabled. The current behavior required the FPU always to be on which is very dangerous if lazy context switching is used. [Joel Note: Some ports explicitly enabled the FPU in the FP save and restore routines to avoid this.] The patch also makes sure (on powerpc only) that the FPU is disabled for integer tasks. Note that this is crucial if deferred fp context switching is used. Otherwise, fp context corruption may go undetected! Also note that even tasks which merely push/pop FP registers to/from the stack without modifying them still MUST be FP tasks - otherwise (if lazy FP context switching is used), FP register corruption (of other, FP, tasks may occur)! Furthermore, (on PPC) by default, lazy FP context save/restore is _disabled_. * shared/include/io.h: Per PR215 address the following issues: - _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only one to know the values) - the affected BSP (shared/motorola) headers have been fixed in a separate "libbsp/powerpc/shared" patch. - the DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the BSP who is using this driver. - the DEC driver also has been fixed to use the newer rtems_bsp_delay_in_bus_cycles() instead of the obsolete delay_in_bus_cycles(). 2001-05-14 Joel Sherrill * shared/include/cpuIdent.c: Account for duplicate numbers. 2001-04-17 Joel Sherrill * shared/include/cpu.h: Added ifndef ASM. 2001-04-03 Joel Sherrill * Closed PR57. The hack is OK as it allows a BSP to override or not at its discretion. * Per PR94, all rtems/score/CPUtypes.h are named rtems/score/types.h. * Per PR94, all rtems/score/CPUtypes.h are named rtems/score/types.h. * mpc8xx/timer/timer.c: Removed #warning declaring providing a default definition for the macros rtems_cpu_configuration_get_timer_least_valid and rtems_cpu_configuration_get_timer_average_overhead. * old-exceptions/rtems/score/cpu.h, new-exceptions/rtems/score/cpu.h: Account for name change. 2001-03-30 Eric Valette * mpc8xx/vectors/Makefile.am, mpc8xx/vectors/README, mpc8xx/vectors/align_h.S mpc8xx/vectors/vectors.S: These files were removed in support of switching the mpc8xx to the use the "new exception processing model." * configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am, mpc8xx/clock/clock.c, mpc8xx/console-generic/console-generic.c, mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c, new_exception_processing/cpu.h, shared/include/byteorder.h, wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new exception processing model." * mpc8xx/exceptions/Makefile.am, mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c, mpc8xx/exceptions/raw_exception.h: New files. 2001-02-27 Ralf Corsepius * mpc505/ictrl/Makefile.am, mpc6xx/clock/Makefile.am, mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am, mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am, old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am, shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS instead of *H_FILES. 2001-01-03 Joel Sherrill * new_exception_processing/cpu.h, old_exception_processing/cpu.c: old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In particular, spurious vector initialization had to be moved on old exception processing model. 2000-11-09 Ralf Corsepius * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS. 2000-11-02 Ralf Corsepius * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal. 2000-10-26 Ralf Corsepius * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to GNU canonicalization. 2000-10-20 Joel Sherrill * mpc8xx/console-generic/console-generic.c: Avoid use of BSP definitions and rely on the new routine mbx8xx_console_get_configuration() to get information. This routine was formerly incorrectly called mbx8xx_console_use_maximum_buffer_size(). binding to the exception code. * configure.in, Makefile.am: Explicitly specify whether an RTEMS_CPU_MODEL is using old or new exception processing. This is important because when building multilib, you do not know the RTEMS_CPU_MODEL. So everything built in a multilib'ed RTEMS must be independent of the exception model and allow for late binding to the exception code. 2000-10-18 Sergei Organov * Added full support for MPC505. * configure.in, mpc505/Makefile.am: Modified to reflect ictrl addition. * old_exception_processing/Makefile.am: Account for ppc_offs.h. * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h. * mpc505/timer/timer.c: Use , not "rtems.h". * mpc505/vectors/vectors.S: Now use constants for exception numbers. * mpc505/ictrl: New directory. * old_exception_processing/ppc_offs.h: New file. * old_exception_processing/cpu.h: Make Nest and Disable levels volatile. * mpc505/vectors/Makefile.am: alignment exception handler now included. * mpc505/ictrl/Makefile.am, mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files. 2000-10-18 Joel Sherrill * mpc8xx/console-generic/console-generic.c: Removed include of by adding BSP dependent routine mbx8xx_console_use_maximum_buffer_size() which can be hard coded or check non-volatile memory for configuration. * mpc8xx/console-generic/console-generic.c: Removed warnings. * mpc6xx/clock/c_clock.h: Removed commented out reference to . * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto. * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of bsp.h and replaced it with use of proper interfaces or explicit externs of required functions and data. 2000-09-04 Ralf Corsepius * mpc505/timer/Makefile.am, mpc505/vectors/Makefile.am, mpc6xx/clock/Makefile.am, mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am, mpc6xx/timer/Makefile.am, mpc6xx/wrapup/Makefile.am, ppc403/clock/Makefile.am, ppc403/console/Makefile.am, ppc403/ictrl/Makefile.am, ppc403/timer/Makefile.am, ppc403/vectors/Makefile.am, shared/include/Makefile.am, shared/src/Makefile.am, wrapup/Makefile.am, mpc8xx/clock/Makefile.am, mpc8xx/console-generic/Makefile.am, mpc8xx/cpm/Makefile.am, mpc8xx/mmu/Makefile.am, mpc8xx/timer/Makefile.am, mpc8xx/vectors/Makefile.am, new_exception_processing/Makefile.am, old_exception_processing/Makefile.am: Include compile.am 2000-08-11 Charles-Antoine Gauthier * mpc8xx/console-generic/console-generic.c: Add support for configuration parameters in NVRAM 2000-08-10 Charles-Antoine Gauthier * mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite): Flush actual buffer. * mpx8xx/console-generic/console-generic.c: Addition of support for shared printk and no termios. 2000-06-08 Eric Valette * mpc8xx/console-generic/console-generic.c: The printk/printf did not work when loaded by EPPCBUG. They did work when loaded with the BDM debugger. I suspected EPPBUG made some nasty things like patching Communication processor microcode... Anyway, the attached patch: 1) Enables to have printk nearly immediately after boot, 2) Make printf work automagically (I do not know why except I make a different initialization for printk that should be overwritten by console init later ?) I let the default to be using EPPCBUG embedded firmware to boot and using this printk early enabler code (LOADED_BY_EPPCBUG and EARLY_CONSOLE) are on.
