2016-01-04Remove H8300 portJoel Sherrill1-19/+0
updates #2452.
2014-02-14score: Add CPU counter supportSebastian Huber1-0/+1
Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.
2013-05-01Using the generic atomic ops to implement UP mode atomic for all ↵WeiY1-0/+1
architectures. SMP atomic port will be later.
2012-11-27score: Add CPU_Exception_frameSebastian Huber1-0/+1
Add CPU port type CPU_Exception_frame and function _CPU_Exception_frame_print(). The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh, sparc64, and v850 use an empty default implementation of _CPU_Exception_frame_print(). Add rtems_exception_frame and rtems_exception_frame_print(). Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal() with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc, and sparc for unexpected exceptions. Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the BSP_PRINT_EXCEPTION_CONTEXT define used in the default bsp_fatal_extension(). Add test sptests/spfatal26.
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-4/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
2012-05-07Revert: Remove CVS IdsJoel Sherrill1-0/+4

2000-06-29This is the initial addition of the port of RTEMS to theJoel Sherrill1-5/+5
Hitachi H8 family. This port was done by Philip Quaife <philip@qs.co.nz> of Q Solutions and sponsored by Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1 to a Hitach H8300H. The port was updated to RTEMS 4.5 style Makefiles/configure by Joel Sherrill <joel@OARcorp.com>. While doing this Joel added support for the h8300-rtems to binutils, gcc, newlib, and gdb. NOTE: Philip submitted a BSP for a Hitachi evaluation board which is being merged as a separate entity.

Other CPUs basically have similar problems (SH:sh7032 vs sh7045, SPARC: erc32.h in score/cpu/sparc), but have been lucky to get around real issues (cf. configuration files below score/cpu/sh/). * From a configuration focused POV this problem boils down to a file/subdirectory selection problem: ppc: 1 or others sh: 1 out of 2 sparc: 1 out of 1 Automake's means to implement such behavior is using conditionals to be evaluated at configuration-time. The old configuration scheme however used make-time conditionals. The SH port was lucky to get around this issue because it applies a selection from a limited set of possible selections, the powerpc however applies a selection from an unlimited set, based on data not being available at configuration time. * Currently I only see two general solutions: 1) make RTEMS_CPU_MODEL available at configuration time, ie. replace make-time configuration by configuration-time configuration 2) Perform the selection at build-time, i.e. always install all files, but use #ifdef #else #endif in source files. This is what the m68k has exploited at other locations inside of the source-tree. => This directory is the last one remaining not using automake below the whole exec/ hierarchy.
