* bsps: Improve interrupt vector enable/disable APISebastian Huber2017-06-201-6/+6
| | | | | | Change bsp_interrupt_vector_enable() and bsp_interrupt_vector_disable() to not return a status code. Add bsp_interrupt_assert() and use it to validate the vector number in the vector enable/disable implementations.

* beagle: pwm polishingPunit Vara2016-07-174-309/+568
| | | | | | | | | . added a README to pwm . added select_pwmss() to select pwmss-generic registers, as opposed to PWM-specific registers . added pwmss_clock_en_status(), beagle_pwmss_is_running() and pwmss_tb_clock_check() . other API improvements . style improvements
* Beaglebone: Update PWM driver imported from BBBIOPunit Vara2016-07-043-385/+515
| | | | | | This patch adapts the previously added Beaglebone PWM code from BBBIO to RTEMS. This work was done in the context of the Google Summer of Code 2016, and further patches will follow to improve the code quality and documentation.
* Beaglebone: Add original BBBIO PWM driverPunit Vara2016-07-042-0/+448
| | | | | | | | | This patch adds the PWM driver code for the Beaglebone Black from BBBIO: https://github.com/VegetableAvenger/BBBIOlib/blob/master/BBBio_lib/BBBiolib_PWMSS.c This commit is for tracking purposes only; the next commit will adapt the code for RTEMS.
* bsps/arm: Change code to explicit selection of cache implementation for ARM ↵Pavel Pisa2016-07-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | BSPs. The original ARM architecture wide cache_.h is changed to dummy version for targets not implementing/enablig cache at all. The ARM targets equipped by cache should include appropriate implementation. Next options are available for now c/src/lib/libbsp/arm/shared/armv467ar-basic-cache/cache_.h basic ARM cache integrated on the CPU core directly which requires only CP15 oparations c/src/lib/libbsp/arm/shared/arm-l2c-310/cache_.h support for case where ARM L2C-310 cache controller is used. It is accessible as mmaped peripheral. c/src/lib/libbsp/arm/shared/armv7m/include/cache_.h Cortex-M specific cache support

* am335x irq handling improvementMartin Galvan2016-02-281-40/+42
| | | | | | | | | | | | | This patch makes the following changes to the Beaglebone IRQ handling code: - Disable support for nested interrupts. - Detect spurious IRQs using the SPURIOUSIRQ field of the INTC_SIR_IRQ register. - Acknowledge spurious IRQs by setting the NewIRQAgr bit of the INTC_CONTROL register. This cleans the SPURIOUSIRQ field and allows new interrupts to be generated. - Improve the get_mir_reg function a bit. Closes #2580.

* beagle sdcard.sh: objcopy 4.12Ben Gras2015-12-271-1/+1

* Beaglebone Black: Fix rtems_gpio_bsp_disable_interrupt disabling all the ↵Martin Galvan2015-12-161-1/+1
| | | | | | | | | | GPIO interrupts Currently, rtems_gpio_bsp_disable_interrupt disables the interrupts for all the pins, not just the one that actually caused the interrupt. This patch fixes that issue. Closes #2497.
* bsps: Delete superfluous bsp_pretasking_hook()Sebastian Huber2015-12-101-1/+0
| | | | | | Use the bsp_predriver_hook() instead. Update #2408.
* Leftover gpio function renameBen Gras2015-11-031-3/+3
| | | | | | Rename rtems_bsp_select_specific_io to rtems_gpio_bsp_select_specific_io. Should've gone with 5c337d7. Fixes #2456.
* Fixes GPIO APIs Naming Convention and CommentsSudarshan Rajagopalan2015-10-211-4/+4
| | | | Closes #2435.
* Beaglebone: fix missing clobber in inline assembly.Marcos Diaz2015-09-101-1/+7
| | | | | | | | flush_data_cache uses R0 directly but doesn't list it as a clobbered register. Compiling with -O3 made this code break, since the function that calls flush_data_cache already uses r0. closes #2416.

* beagle bsp: delete TIMER_FREQ, TIMER_COUNTBen Gras2015-03-141-4/+0
| | | | | | unused and poorly named (no prefix) and colliding with sp68. Closes #2302.
* bsp/beagle: Fix some warningsBen Gras2014-12-152-3/+3
| | | | | | | The extra includes in console_*.c are to solve a 'no previous prototype' warning. Solves #2212 in trac.
* beagle bsp: disable watchdog on am335xBen Gras2014-12-051-0/+9
| | | | | | | | | | | | On recent u-boots, the watchdog is turned on / left enabled. The Beaglebone Black rev. C ships with such a u-boot internally so any application booting from it must disable the watchdog. Therefore this change is needed to boot an RTEMS app out-of-the-box on a BBB Rev C - otherwise the user button must be held during boot (to bypass the stock uboot) or the internal uboot must be updated. To allow for a better out-of-the-box experience, we just turn off the watchdog.
* bsps/arm: Add .nocache sectionSebastian Huber2014-11-271-0/+2
| | | | | This section can be use to provide a cache coherent memory area via rtems_cache_coherent_add_area().

* BSP for several Beagle productsBen Gras2014-11-0336-3221/+1485
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifically the beagleboard, beagleboard xM, beaglebone, beaglebone black. More info on these targets: http://www.beagleboard.org/ This commit forms a basic BSP by combining Claas's work with . new clock and irq code and definitions for beagle targets (beagleboard and beaglebones), mostly reused from the Minix codebase, thus making irqs, ticks and non-polled console mode work too . new timer code for ns timing with high timer resolution, 24MHz on the AM335X and 13MHz on the DM37XX . select the console uart based on target at configure time . removing all the lpc32xx-specific macros and code and other unused code and definitions that the beagle bsp was based on . re-using some standard functions instead of lpc32xx versions . fixed some whitespace problem in preinstall.am . fixed some compile warnings . configure MMU: set 1MB sections directly in the TTBR, just to show the difference between cacheable RAM and non-cacheable device memory and invalid ranges; this lets us turn on caches and not rely on boot loader MMU configuration. Verified to work when MMU is initially either on or off when RTEMS gets control. Thanks for testing, commentary, improvements and fixes to Chris Johns, Brandon Matthews, Matt Carberry, Romain Bornet, AZ technology and others. Signed-Off-By: Ben Gras <beng@shrike-systems.com>
