* tests/mmap_test.c: Diagnostic prints for failure cases.
2002-04-24 Jesper Skov <jskov@redhat.com>
* cdl/hal_arm_sa11x0.cdl: CYGPRI_KERNEL_TESTS_DHRYSTONE_PASSES added.
2002-01-29 Jesper Skov <jskov@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Removed CRUFT_H.
* include/hal_sa11x0.h: Moved CYGARC_PHYSICAL_ADDRESS definition
to:
* include/var_io.h: this file.
2002-01-28 Jesper Skov <jskov@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Declare var_io.h file.
Tug RedBoot requirements away in a component properly controlled
by the RedBoot presence.
* include/var_io.h: Added.
2002-01-25 Jesper Skov <jskov@redhat.com>
* include/hal_sa11x0.h (CYGARC_PHYSICAL_ADDRESS): Added.
* src/redboot_linux_exec.c: Moved to arch directory.
* cdl/hal_arm_sa11x0.cdl: Replaced options with requirements to
arch options.
2002-01-25 David Woodhouse <dwmw2@cambridge.redhat.com>
* src/redboot_linux_exec.c (do_exec): Trick the compiler into
thinking that the end1 and lab1 labels are both actually used,
so it doesn't move them around.
2002-01-22 David Woodhouse <dwmw2@cambridge.redhat.com>
* src/redboot_linux_exec.c (do_exec): Pass ATAG_MEM to Linux
kernel, having tried to obtain the appropriate numbers from the
MLT header file. This could probably do with some improvement -
the actual information we need isn't necessarily present in the
required form.
2002-01-14 David Woodhouse <dwmw2@cambridge.redhat.com>
* src/redboot_linux_exec.c (do_exec): Use load start/end
parameters as defaults. Don't copy image if specified length is
zero.
2001-10-31 Jonathan Larmour <jlarmour@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Indicate support of variable baud rates.
2001-10-09 Hugo Tyson <hmt@redhat.com>
* src/hal_diag.c (cyg_hal_plf_serial_isr): As well as the sticky
Rx Idle bit, clear the sticky bits for interrupts for start or end
of a line break, otherwise messing with the wiring can cause an
interrupt loop and hang the target.
2001-08-22 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c:
printf() is no longer a part of RedBoot. Thus all programs
must use diag_printf() and related functions instead.
2001-08-21 Hugo Tyson <hmt@redhat.com>
* include/hal_var_ints.h (HAL_CLOCK_LATENCY()): Define this if
it's needed, for the routine below.
* src/sa11x0_misc.c (hal_clock_latency): A neater fix for the
below change: use a separate routine for measuring latency, which
assumes it is called in the ISR, before the clock is reset.
2001-08-20 Hugo Tyson <hmt@redhat.com>
* src/sa11x0_misc.c (hal_clock_read): Make hal_clock_read() return
the true value (as expected by the kernel latency test) from the
last interrupt if we just had that interrupt and didn't yet reset
the clock. Otherwise ISR latencies are reported as one tick (1cS,
10000uS) too large.
2001-07-27 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c: Fix copyright disclaimers to satisfy
original owner (Linux kernel maintainer Russell King).
2001-07-23 Gary Thomas <gthomas@redhat.com>
* src/sa11x0_misc.c (hal_IRQ_handler): Support board/platform
specific [extended] interrupts. On the SA11x0, these would often
be cascaded via GPIO logic. Use of extended macros allows SA11x0
variant code to handle the general case, with board specific code
defined by board packages. Look at the iPAQ board package for
a sample of how to use this.
2001-05-19 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c (do_exec): Protect compilation - scripting
is configurable.
2001-05-17 Gary Thomas <gthomas@redhat.com>
* src/hal_diag.c: Allow baud rate to be settable.
2001-04-16 Gary Thomas <gthomas@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Add CDL to describe CPU family.
2001-03-23 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c (do_exec):
Entry point must be a physical address.
* cdl/hal_arm_sa11x0.cdl:
Allow platforms to override default clock speed.
2001-03-20 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c (do_exec): Improve wait timeout.
2001-03-07 Hugo Tyson <hmt@redhat.com>
* src/redboot_linux_exec.c: Do not build anything if
HAL_PLATFORM_MACHINE_TYPE is not defined.
2001-03-02 Gary Thomas <gthomas@redhat.com>
* cdl/hal_arm_sa11x0.cdl: HAL_PLF_INIT stuff moved to hal/common.
2001-03-01 Gary Thomas <gthomas@redhat.com>
* src/sa11x0_misc.c:
* cdl/hal_arm_sa11x0.cdl: New interface CYGINT_HAL_PLF_IF_INIT
which, if defined, indicates that the platform has plf_if_init.
2001-03-01 Hugo Tyson <hmt@redhat.com>
* src/sa11x0_misc.c: Remove warnings from lack of prototype for
plf_if_init() - for platforms that don't have it.
2001-02-28 Gary Thomas <gthomas@redhat.com>
* src/sa11x0_misc.c: Allow platform to perform additional
I/O initialization (virtual vector based). The function
plf_if_init() can be overridden by platform code for this.
2001-02-28 Hugo Tyson <hmt@redhat.com>
* include/hal_sa11x0.h (SA11X0_TUCR_RESERVED_BITS):
(SA11X0_TUCR_EXTERNAL_MEMORY_MASTER): Add definitions of these
bits for enabling an external bus master.
2001-02-28 Hugo Tyson <hmt@redhat.com>
* include/hal_sa11x0.h (SA11X0_OWER): Add OS Timer Watchdog Match
Enable Register for use by Watchdog package.
(SA11X0_OWER_ENABLE): And a long-winded "1" to enable it.
2001-02-24 Gary Thomas <gthomas@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Add RedBoot commands/options.
* src/redboot_linux_exec.c: New file - RedBoot commands to
support booting Linux kernel.
2001-02-23 Jesper Skov <jskov@redhat.com>
* include/hal_cache.h (HAL_FLASH_CACHES_OLD_MACROS): Some
platforms use deprecated cache handling macros.
2001-02-20 Jonathan Larmour <jlarmour@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Clarify CYGHWR_HAL_ARM_SA11X0_UART1,3
description.
2001-02-20 Gary Thomas <gthomas@redhat.com>
* src/hal_diag.c:
* cdl/hal_arm_sa11x0.cdl: Add CDL to control which serial ports
are available/used.
2001-02-20 Hugo Tyson <hmt@redhat.com>
2001-02-12 Robin Farine <acnrf@dial.eunet.ch>
* include/hal_sa11x0.h (SA11X0_IRQ_GPIO_9_EDGE_DETECT): Define
this to be 9 not 0 - simple typo. Thanks Robin!
2001-02-19 Hugo Tyson <hmt@redhat.com>
2001-02-12 Robin Farine <acnrf@dial.eunet.ch>
* src/sa11x0_misc.c (hal_clock_reset): Handles SA11X0_OSCR as a
free running counter.
(hal_clock_read): Adapts to changes in hal_clock_reset().
(hal_delay_us): Likewise.
There is only one counting register (OSCR), but multiple match
registers and interrupt sources (OSMR1-OSMR3). Setting our match
register to COUNT and the counter register to 0 each tick makes it
very hard to use the other match registers - whereas they are
intended for easy general use.
This change sets our match register OSMR0 to the next time
interval and leaves the OSCR freerunning so that other match
registers can easily be used, which is much more flexible, and
much more what was intented.
Because the OSCR is just a counter, and the match registers
compare only for exact equality, no special measures to deal with
the counter wrapping/overflowing are needed.
2001-02-08 Jesper Skov <jskov@redhat.com>
* src/hal_diag.c: Replace CYGSEM_HAL_DIAG_MANGLER_None with
CYGDBG_HAL_DIAG_TO_DEBUG_CHAN.
2001-02-01 Jesper Skov <jskov@redhat.com>
* include/hal_var_ints.h: Include registers definitions used in
reset macro.
2001-01-31 Jesper Skov <jskov@redhat.com>
* src/hal_diag.c: Replaced CYGDBG_HAL_DIAG_DISABLE_GDB_PROTOCOL
with CYGSEM_HAL_DIAG_MANGLER_None
2001-01-26 Jesper Skov <jskov@redhat.com>
* src/hal_diag.c: Removed CYGSEM_HAL_VIRTUAL_VECTOR_DIAG check.
* include/plf_stub.h: Moved reset macro to
* include/hal_var_ints.h: this file.
2001-01-05 Hugo Tyson <hmt@redhat.com>
* include/hal_mm.h: Change bitfields within memmap entry to
unsigned, so that we can compare values successfully - otherwise
"0x02" sign-extends and is never equal after promotion!
* include/hal_cache.h: Include the platform memory map
interrogation definitions from <cyg/hal/plf_mmap.h> and header for
the new functions below.
* src/sa11x0_misc.c (hal_virt_to_phys_address):
(hal_phys_to_virt_address):
(hal_virt_to_uncached_address): New functions which inspect the
real memory map in force to verify the static translations defined
in the efficient macro versions.
* tests/mmap_test.c (endif): New file: testcase for memory map
interrogation macros and verification functions.
* cdl/hal_arm_sa11x0.cdl: Build the testcase.
2000-12-13 Hugo Tyson <hmt@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Define a symbol CYGBLD_HAL_VAR_INTS_H so
that the architectural HAL can see <cyg/hal/hal_var_ints.h> below.
* include/hal_var_ints.h: New file; actually a copy of all the
platforms' hal_platform_ints.h for all the sa11x0 platforms.
* include/hal_mm.h: New file; actually an excerpt from all the
platforms' $PLATFORM_misc.h for all the sa11x0 platforms, which
describes MM table layout and macros for initializing it.
2000-12-12 Gary Thomas <gthomas@redhat.com>
* cdl/hal_arm_sa11x0.cdl: Allow RTC clock rate to be changable.
2000-12-04 Hugo Tyson <hmt@redhat.com>
* include/hal_cache.h: Consistently ensure that ARM registers used
in MCR ops to cache-control coprocessors, where the data doesn't
matter, all actually have data zero ("SBZ") as in the Jaggar book.
This may well not be necessary, but for the sake of making sure...
2000-12-01 Hugo Tyson <hmt@redhat.com>
* include/hal_cache.h: Define addressable cache line operations
HAL_DCACHE_STORE(), HAL_DCACHE_INVALIDATE(), HAL_DCACHE_FLUSH()
now that I have understood how come the test (kcache2) was
failing. See kernel ChangeLog for details. Also tidied up a
couple of other minor details.
2000-11-27 Gary Thomas <gthomas@redhat.com>
* src/hal_diag.c (init_channel): UART setup required on Brutus as well.
2000-11-21 Gary Thomas <gthomas@redhat.com>
* src/hal_diag.c (init_channel): Disable broken uart setups on platforms
other than the SA1110MM, since this code seems to be somewhat broken.
2000-10-25 Drew Moseley <dmoseley@redhat.com>
* src/hal_diag.c: Added UART1 support for SA1100 targets.
* include/hal_sa11x0.h: Added GPIO bit definitions.
2000-07-14 Gary Thomas <gthomas@redhat.com>
* include/hal_diag.h (HAL_DELAY_US): Define.
* src/sa11x0_misc.c (hal_delay_us): New function. Used to
provide timers/delays in non-kernel systems.
2000-07-05 Jesper Skov <jskov@redhat.com>
* cdl/hal_arm_sa11x0.cdl:
* src/hal_diag.c:
Cleaned up channel options.
