2003-02-24 Jonathan Larmour <jifl@eCosCentric.com> |
|
* cdl/ser_mn10300.cdl: Remove irrelevant doc link. |
|
2001-09-10 Jonathan Larmour <jlarmour@redhat.com> |
|
* cdl/ser_mn10300.cdl: |
Fix 234000->230400 typo. |
|
2000-08-01 Jonathan Larmour <jlarmour@redhat.co.uk> |
|
* src/mn10300_serial.c (mn10300_serial_set_config): Now use keys to make |
more flexible. |
|
2000-06-22 Hugo Tyson <hmt@cygnus.co.uk> |
|
* cdl/<yournamehere>.cdl: Remove the comment on the empty |
include_files directive; the tools now support this correctly. |
This keeps internal include files internal. |
|
2000-04-11 Hugo Tyson <hmt@cygnus.co.uk> |
|
* cdl/ser_mn10300.cdl: Change the parent from CYGPKG_IO_SERIAL |
(which is enabled most of the time) to CYGPKG_IO_SERIAL_DEVICES |
(which is not...) thus allowing convenient control independent of |
platform. Also enable all individual devices by default, now, so |
that they can be enabled simply by enabling the above new parent. |
|
2000-04-07 Hugo Tyson <hmt@cygnus.co.uk> |
|
* ecos.db: Re-organize device packages. This is a massive change |
involving deleting all the sources for serial and ethernet drivers |
from where they used to live in |
packages/io/serial/current/src/ARCH/PLATFORM.[ch] |
packages/net/drivers/eth/PLATFORM/current/src/... |
and reinstating them in |
packages/devs/serial/ARCH/PLATFORM/current/src/... |
packages/devs/eth/ARCH/PLATFORM/current/src/... |
|
All these new packages are properly defined in ecos.db, and are |
all of type "hardware" so that a "target" can grab them. |
|
This directory layout is descriptive of the devices we have right |
now, arch and platform are separate levels just to make it easier |
to navigate in the filesystem and similar to the HAL structure in |
the filesystem. |
|
It is *not* prescriptive of future work; for example, the mythical |
common highly-portable 16550 serial driver which works on many |
targets would be called "devs/serial/s16550/current", or a serial |
device for a particular board (cogent springs to mind) that can |
work with different CPUs fitted is "devs/serial/cogent/current". |
|
Changelogs have been preserved and replicated over all the new |
packages, so that no history is lost. |
|
The contents of individual source files are unchanged; they build |
in just the same emvironment except for a very few cases where the |
config file name changed in this movement. |
|
Targets in ecos.db have been redefined to bring in all relevant |
hardware packages including net and serial drivers (but the newly |
included packages are only active if their desired parent is |
available.) |
|
The names of CDL options (and their #defines of course) stay the |
same for the serial drivers, for backward compatibility. |
|
* templates/*/current.ect: these have had CYGPKG_IO_SERIAL added |
rather than it being in (almost) all target definitions. |
|
2000-04-05 Jonathan Larmour <jlarmour@redhat.co.uk> |
|
* src/common/tty.c (tty_read): CRLF conversion should use \r\n not \n\r |
(tty_write): Similarly |
|
* include/ttyio.h: Update CYG_TTY_IN_FLAGS_CRLF and |
CYG_TTY_IN_FLAGS_CRLF to match |
|
2000-03-31 Jesper Skov <jskov@redhat.com> |
|
* cdl/ser_sh_edk7708.cdl: Limit legal baud rate range. |
* src/sh/sh_sci_serial.c: Use baud rate macro instead of hardwired |
constants. |

|
2000-01-19 Hugo Tyson <hmt@cygnus.co.uk> |

value supplied for interrupt priority - it may be unused, but it |
is asserted for range. Initialize the diagnostic channel if on an |
MBX and if NOT using SMC1 ourselves, to ensure that diag output |
and built-in stubs work correctly; otherwise reset the quicc and |
ignore SMC1 as before. Fix various warnings, mostly about |
casting/arg-passing/assigning away volatile. |
|
1999-08-31 Jesper Skov <jskov@cygnus.co.uk> |

|
Imported following changes from development branch: |
|
1999-08-11 Nick Garnett <nickg@cygnus.co.uk> |
|
* tests/serial5.c: Modified config test for boards that need a lower |
speed for this test. |
|
* tests/ser_test_protocol.inl: Removed 14400 baud tests for all |
MN10300 variants. The MN10300 cannot currently do this speed. |
|
* src/mn10300/mn10300_serial.c: Tidied up the transmit interrupt |
enable/disable code to be variant specific. |
|
* include/pkgconf/io_serial.h: Undid Jonathan's change, since the |
same options are used for all MN10300 variants. |
|
1999-08-10 Jonathan Larmour <jlarmour@cygnus.co.uk> |
|
* include/pkgconf/io_serial.h: |
Reparent CYGPKG_IO_SERIAL_MN10300 from under CYGPKG_HAL_MN10300 to |
CYGPKG_HAL_MN10300_AM32_STDEVAL1 since it's stdeval1 specific |
|
1999-08-04 Nick Garnett <nickg@cygnus.co.uk> |
|
* tests/ser_test_protocol.inl: |
Changed names of MN10300 defines tested. Added AM33 definitions. |
|
* src/mn10300/mn10300_serial.c: |
Modified driver to work on am33 too. This simply requires some |
alternate definitions of things like register addresses and some |
bits in them plus some extra parameterization of some register |
values. |
|
* src/PKGconf.mak: |
Added am33 to list of architectures supporting serial lines. |
|
1999-07-28 Gary Thomas <gthomas@cygnus.co.uk> |
|
* include/pkgconf/io_serial.h: Update descriptions to be more |
generic (CL7x11 instead of CL7211). |
|
1999-07-28 Jonathan Larmour <jlarmour@cygnus.co.uk> |
|
* include/pkgconf/io_serial.h: Correct typos in CDL description |
for serial port 2 driver |
|
1999-07-26 Hugo Tyson <hmt@cygnus.co.uk> |
|
* src/arm/ebsa285_serial.c: New file: device driver for the serial |
device of the Intel StrongARM EBSA-285 evaluation board. |
|
* include/pkgconf/io_serial.h (CYGPKG_IO_SERIAL_ARM_EBSA285): |
Config for it. |
|
* src/PKGconf.mak (EXTRAS_COMPILE): Compile it. |
|
* tests/ser_test_protocol.inl (TEST_SER_DEV): Enable testing of it. |
|
1999-07-08 Jesper Skov <jskov@cygnus.co.uk> |
|
* tests/ser_test_protocol.inl (change_config): Changed implementation. |
|
1999-06-27 Gary Thomas <gthomas@cygnus.co.uk> |
|
* src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): More robust |
initialization, with data cache disabled. This seems to fix the |
random failures described below. |
|
* tests/ser_test_protocol.inl: Add configuration for QUICC/MBX860. |
Added some delays in the configuration change code to make QUICC |
happy [didn't help much although the manual says they are required]. |
|
* src/powerpc/quicc_smc_serial.h (UART_BITRATE): Rewrote macro to |
match what the Linux driver uses - still doesn't work well, though. |
|
* src/powerpc/quicc_smc_serial.c: Lots of changes trying to get the |
serial driver working and robust. At this point it works quite well, |
using the default buffer sizes. Changing from the defaults seem to |
easily break it though, certainly on input. Also, changing the baud |
rate seems to not work reliably. |
|
* src/common/serial.c: Add some tracing/debug info to try and debug |
problems with QUICC serial driver. These are hard disabled with |
"XX_" prepended to "CYGDBG_DIAG_BUF". Enabling them gives information |
about how/when data are delivered from the serial driver. |
|
* include/pkgconf/io_serial.h: Adjust limits and defaults on number and |
size of buffers with values that seem to work. |
|
1999-06-21 Jesper Skov <jskov@cygnus.co.uk> |
|
* src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit |
to avoid compiler warnings. |
|
1999-06-21 Gary Thomas <gthomas@cygnus.co.uk> |
|
* include/pkgconf/io_serial.h: Fix CDL for number of buffers. |
|
* src/powerpc/quicc_smc_serial.c: Force number of buffers = 1. |
|
1999-06-20 Gary Thomas <gthomas@cygnus.co.uk> |
|
* include/pkgconf/io_serial.h: Some clean up (removed commented |
obsolete CDL parenting structure). |
Add support for Motorola PowerPC QUICC/SMC. |
|
* src/arm/cma230_serial.c: |
* src/arm/cl7211_serial.c: |
* src/arm/aeb_serial.c: |
* src/arm/pid_serial_with_ints.c: Use #include to get 'diag_printf()' |
prototypes. |
|
1999-06-17 Gary Thomas <gthomas@cygnus.co.uk> |
|
* src/arm/cl7211_serial.c (cl7211_serial_start_xmit): Fix race which |
cause xmitter to get stuck. |
|
1999-06-16 Jesper Skov <jskov@cygnus.co.uk> |

|
1999-05-31 Jesper Skov <jskov@cygnus.co.uk> |
|
* src/sh/sh_serial.c: Fixed receive interrupts and added handler for |
error interrupts. |

|
* io/serial/current/src/PKGconf.mak: |
* io/serial/current/tests/ser_test_protocol.inl: |
* include/pkgconf/io_serial.h: |
Renamed SH platform package to edk7708. |
|
1999-05-27 Jesper Skov <jskov@cygnus.co.uk> |
|
* tests/ser_test_protocol.inl: Added ability to change options in |
host software. |
|
1999-05-27 Jonathan Larmour <jlarmour@cygnus.co.uk> |
|
* src/mn10300/mn10300_serial.c (mn10300_serial_config_port): |
Wait for the serial device to become acquiescent before disabling |
it. This prevents cygmon's outgoing characters getting corrupted |
due to transmission being disabled. |
Fix for PR 20047 |
|
1999-05-26 Gary Thomas <gthomas@cygnus.co.uk> |

Note that currently serial input does not work for CON1 since Cygmon is |
taking all of the receive interrupts for itself. |
