/v2_0/ChangeLog
0,0 → 1,1209
2003-02-24 Jonathan Larmour <jifl@eCosCentric.com> |
|
* cdl/ser_arm_ebsa285.cdl: Remove irrelevant doc link. |
|
2001-09-10 Jonathan Larmour <jlarmour@redhat.com> |
|
* cdl/ser_arm_ebsa285.cdl: |
Fix 234000->230400 typo. |
|
2000-10-12 Jesper Skov <jskov@redhat.com> |
|
* cdl/ser_arm_ebsa285.cdl: Testing parameters moved here. |
|
2000-08-01 Jonathan Larmour <jlarmour@redhat.co.uk> |
|
* src/ebsa285_serial.c (ebsa285_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. |
|
2000-04-12 Hugo Tyson <hmt@cygnus.co.uk> |
|
* src/ebsa285_serial.c (ebsa285_serial_init): Fix silly debug |
message - enabled by serial1 test permutation. |
|
2000-04-12 Hugo Tyson <hmt@cygnus.co.uk> |
|
* src/ebsa285_serial.c (ebsa285_serial_tx_DSR): Record |
whether tx is to be enabled in ebsa285_chan->tx_active, so that |
the DSR does not universally unmask it regardless. That led to an |
interrupt loop, when the DSR callback had turned off the tx. |
Also removed a typo - rx data was being read twice! |
|
2000-04-11 Hugo Tyson <hmt@cygnus.co.uk> |
|
* cdl/ser_arm_ebsa285.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. |
|
2000-03-28 John Dallaway <jld@cygnus.co.uk> |
|
* cdl/io_serial.cdl, |
cdl/ser_arm_aeb.cdl, |
cdl/ser_arm_cma230.cdl, |
cdl/ser_arm_edb7xxx.cdl, |

|
* cdl/ser_mips_jmr3904.cdl: Rename devices to match CDL naming. |
|
2000-02-29 Jonathan Larmour <jlarmour@redhat.co.uk> |
|
* include/serialio.h: Correct baud rate typo: 230400 rather than |
234000. Thanks to Grant Edwards for the report. |
|
2000-02-28 Gary Thomas <gthomas@cygnus.co.uk> |
|
* src/powerpc/quicc_smc_serial.c: Use standard 'diag_dump_buf()'. |
|
2000-02-28 Jesper Skov <jskov@redhat.com> |
|
* tests/ser_test_protocol.inl: Allow 115200 baud on Cogent |
again. Fixed interrupt problem. |
|
2000-02-22 Jesper Skov <jskov@redhat.com> |
|
* tests/ser_test_protocol.inl: Don't use 115200 baud on |
Cogent. Our slower boards can't keep up. |

|
* cdl/ser_powerpc_cogent.cdl: Fix incorrect dependency. |

|
2000-02-10 Jonathan Larmour <jlarmour@redhat.co.uk> |
|
* src/mn10300/mn10300_serial.c: Ensure all CYG_HAL_MN10300_* |
preprocessor conditionals use the correct CYGPKG_HAL_MN10300_AM3* form |
now. |
|
2000-02-03 Jesper Skov <jskov@redhat.com> |
|
* src/powerpc/quicc_smc_serial.c: CYG_HAL_POWERPC_x->CYGPKG_... |

|
2000-01-28 Gary Thomas <gthomas@cygnus.co.uk> |
|
* src/common/tty.c (tty_read): Fix problem with backspace at start |
of line (size must be 'signed' for compare to work). |
|
2000-01-19 Hugo Tyson <hmt@cygnus.co.uk> |
|
* cdl/*.cdl: Add descriptions to a number of options &c which were |
lacking same, also tidied up other typos as noticed en passant. |
|
2000-01-17 Gary Thomas <gthomas@cygnus.co.uk> |
|
* src/common/tty.c (tty_read): Avoid echoing "backspace/erase" at |
start of line. |
|
2000-01-05 Gary Thomas <gthomas@cygnus.co.uk> |
|

case where an interrupt represents multiple events. |
|
1999-11-19 Gary Thomas <gthomas@cygnus.co.uk> |
|

|
1999-10-25 Gary Thomas <gthomas@cygnus.co.uk> |
|
* src/arm/pid_serial.h (ISR_RxTO): Define - character received but |
not handled "promptly". |
|
* src/arm/pid_serial_with_ints.c (pid_serial_DSR): Handle rcv interrupts |
properly (can't ignore them even with TO bit set). |
|
* src/arm/cl7211_serial.c (cl7211_serial_rx_DSR): Need to handle all |
input (empty input FIFO) otherwise characters get dropped. |
|
1999-10-15 Jesper Skov <jskov@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. |

|
1999-08-12 Nick Garnett <nickg@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. |
|
