#
# $Id$
#
# Goal is to have BSPs build almost completely automatically from a template
# and information that comes from SOPC Builder as a .PTF file. Most of the
# code will go to a shared/ BSP directory.
#
# Ideally, updates to the PTF shouldn't cause any pain for the maintainer
# of a specific BSP (possibly with enhancements not covered by the
# automatic BSP creation).
#
# Some first steps toward utilizing SOPC Builder PTF output can be found
# in top level /tools/cpu/nios2. Also see the README there.
#
# Implemented (in shared/ subdirectory)
# Clock driver
# Timer driver
# Console via JTAG UART
#
# Todo;
# Support more peripherals. My priorities:
# - (improve) Altera Avalon JTAG UART
# - Altera Avalon UART
# - OpenCores.org I2C Master
# - Altera SPI Core / EPCS Configuration Device
# - OpenCores.org 10/100 Ethernet MAC (use existing driver)
# - (more) Altera Avalon Timer
#
# Put all drivers aside in a shared/ subdirectory.
# Update the "times" file for NIOS2 with and without icache.
#
# Missing (although it looks like it's there)
# Data cache handling (for now, don't use the "fast" NIOS2)
# SHM support (just taken over the code from no_cpu/no_bsp)

have the same options.
2009-04-06 Joel Sherrill <joel.sherrill@oarcorp.com>
* startup/linkcmds: Move stack so it does not overlap workarea.
2009-03-26 Joel Sherrill <joel.sherrill@oarcorp.com>
* Makefile.am, console/console.c, startup/linkcmds: Now links but
clearly the starting stack overlaps regular memory and needs to be
moved.

2009-03-02 Joel Sherrill <joel.sherrill@oarcorp.com>

compiles again but applications do not link.
2008-12-04 Joel Sherrill <joel.sherrill@oarcorp.com>
* bsp_specs: Move -e start from *link to *startfile to avoid warning
for undefined entry symbol when linking relocatables with binutils
2.19.

* configure.ac: Make letting boot_card() handle work area allocation
mandatory. Rename RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION to
BSP_BOOTCARD_OPTIONS.
2008-09-23 Joel Sherrill <joel.sherrill@oarcorp.com>
* Makefile.am, configure.ac: BSP specific bsp_cleanup() is a dupe of a
shared one.
* startup/bspclean.c: Removed.
2008-09-18 Joel Sherrill <joel.sherrill@oarcorp.com>
* include/bsp.h: Remove unnecessary boilerplate comments.
2008-09-16 Joel Sherrill <joel.sherrill@oarcorp.com>

bsp_get_work_area() implementation.
* startup/bspgetworkarea.c: Removed.
2008-09-14 Joel Sherrill <joel.sherrill@oarcorp.com>
* Makefile.am, startup/bspstart.c: Create bsp_get_work_area() into its
own file and use BSP Framework to perform more initialization.
* startup/bspgetworkarea.c: New file.
2008-09-10 Joel Sherrill <joel.sherrill@oarcorp.com>
* include/bsp.h: Review of all bsp_cleanup() implementations. In this
phase, all prototypes were removed from bsp.h and empty
implementations were removed and made to use the shared stub.
2008-09-05 Ralf Corsépius <ralf.corsepius@rtems.org>
* console/console.c, timer/timer.c: Convert to "bool".
2008-08-31 Joel Sherrill <joel.sherrill@oarcorp.com>
* timer/timer.c: Eliminate empty function from every benchmark timer
driver. Fix spelling.
2008-08-31 Joel Sherrill <joel.sherrill@oarcorp.com>
* timer/timer.c: Rename timer driver methods to follow RTEMS
programming conventions.
2008-05-15 Joel Sherrill <joel.sherrill@OARcorp.com>
* startup/bspstart.c: Add capability for bootcard.c BSP Initialization
Framework to ask the BSP where it has memory for the RTEMS Workspace
and C Program Heap. These collectively are referred to as work area.
If the BSP supports this, then it does not have to include code to
split the available memory between the two areas. This reduces the
amount of code in the BSP specific bspstart.c file. Additionally, the
shared framework can initialize the C Library, call
rtems_debug_enable(), and dirty the work area memory. Until most/all
BSPs support this new capability, if the BSP supports this, it should
call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
When the transition is complete, this autoconf macro can be removed.
2008-05-14 Joel Sherrill <joel.sherrill@OARcorp.com>
* Makefile.am: Rework to avoid .rel files.
2008-05-12 Joel Sherrill <joel.sherrill@OARcorp.com>
* startup/bspstart.c: Refactored and renamed initialization routines to
rtems_initialize_data_structures, rtems_initialize_before_drivers,
rtems_initialize_device_drivers, and
rtems_initialize_start_multitasking. This opened the sequence up so
that bootcard() could provide a more robust and flexible framework
which is easier to explain and understand. This also lays the
groundwork for sharing the division of available memory between the
RTEMS workspace and heap and the C library initialization across all
BSPs.
2008-03-03 Joel Sherrill <joel.sherrill@OARcorp.com>
* startup/linkcmds: Add wildcard to gcc_except_table section so
programs compiled with gcc 4.3.x can link.
2007-12-11 Joel Sherrill <joel.sherrill@OARcorp.com>
* clock/clock.c, include/bsp.h, startup/bspstart.c: Eliminate copies of
the Configuration Table. Use the RTEMS provided accessor macros to
obtain configuration fields.
2007-12-04 Joel Sherrill <joel.sherrill@OARcorp.com>
* console/console.c, include/bsp.h, startup/bspstart.c: Move
interrupt_stack_size field from CPU Table to Configuration Table.
Eliminate CPU Table from all ports. Delete references to CPU Table in
all forms.
2007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>
* console/console.c, startup/bspstart.c: Moved most of the remaining
CPU Table fields to the Configuration Table. This included
pretasking_hook, predriver_hook, postdriver_hook, idle_task,
do_zero_of_workspace, extra_mpci_receive_server_stack,
stack_allocate_hook, and stack_free_hook. As a side-effect of this
effort some multiprocessing code was made conditional and some style
clean up occurred.
2007-09-12 Joel Sherrill <joel.sherrill@OARcorp.com>
PR 1257/bsps
* startup/bspclean.c: Code outside of cpukit should use the public API
for rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
public API and directly accessing _CPU_ISR_Disable and
_CPU_ISR_Enable, they were bypassing the compiler memory barrier
directive which could lead to problems. This patch also changes the
type of the variable passed into these routines and addresses minor
style issues.
2007-04-12 Ralf Corsépius <ralf.corsepius@rtems.org>
* bsp_specs: Remove qrtems_debug.
Remove *cpp:.
2007-03-12 Joel Sherrill <joel@OARcorp.com>
* include/coverhd.h: Correct license URL and/or fix mistake in
copyright notice. Both of these mistakes appear to be from code
submitted after these changes were made previously.
2007-01-08 Ralf Corsépius <ralf.corsepius@rtems.org>
* Makefile.am: Use preinstall.am.
2006-12-02 Ralf Corsépius <ralf.corsepius@rtems.org>
* configure.ac: New BUG-REPORT address.
2006-11-15 Joel Sherrill <joel@OARcorp.com>
* Makefile.am: Merge c_rtems_main() into boot_card(). This eliminated a
file and simplified initialization.
2006-10-17 Ralf Corsépius <ralf.corsepius@rtems.org>
* Makefile.am: Remove superfluous -DASM.
2006-10-17 Ralf Corsépius <ralf.corsepius@rtems.org>
* configure.ac: Require autoconf-2.60. Require automake-1.10.
2006-08-10 Joel Sherrill <joel@OARcorp.com>
* .cvsignore: New file.
2006-08-09 Kolja Waschk <waschk@telos.de>
* clock/clock.c: New file.
2005-12-12 Kolja Waschk
