2017-12-19ARM BSPs: Simplify bsp_specsJoel Sherrill1-5/+1
Updates #3520.
2017-12-15bsps/arm: Fix move <libcpu/arm-cp15.h> to cpukitSebastian Huber2-5/+0

2017-11-29arm/*/bsp_specs: Remove extra space to increase consistencyJoel Sherrill1-1/+1
Updates #3520.
2017-11-27libbsp/*/*/configure.ac: Remove references to bsp_specs in AC_CONFIG_SRCDIRJoel Sherrill1-1/+1
Updates #3250.
2017-11-27bsps: Provide <tm27.h> in each BSPSebastian Huber3-2/+3
Since the <tm27.h> is highly BSP-dependent and used only by the tm27 test program we must provide this header file for each BSP. Without the preinstall build target each header file must have a unique source header file. Update #3254.
2017-11-24Remove coverhd.hSebastian Huber2-6/+1
This header file contained timing overhead values which are hard to maintain. Update #3254.
2017-11-22bsps: Simplify RTEMS_BSP_CLEANUP_OPTIONSSebastian Huber1-1/+1
Remove BSP-specific defaults for RTEMS_BSP_CLEANUP_OPTIONS to simplify the BSP configuration and documentation. Change defaults to: BSP_PRESS_KEY_FOR_RESET=0 BSP_RESET_BOARD_AT_EXIT=1 BSP_PRINT_EXCEPTION_CONTEXT=1
2017-11-17getentropy: Add cpu counter based implementation.Christian Mauderer1-0/+1
Update #3239.
2017-09-22bsps: Generalize bsp_fdt_map_intr()Sebastian Huber1-2/+2
Pass all interrupt cells to bsp_fdt_map_intr() since some platforms use an array to describe an interrupt. Update #3090.
2017-09-18bsps: Clock_driver_support_install_isr()Sebastian Huber1-5/+2
Remove old ISR parameter since is not used by the clock driver shell. Make an implementation optional. Update #3139.
2017-09-12Simplify and unify BSP_output_charSebastian Huber1-3/+0
The BSP_output_char should output a char and not mingle with high level processing, e.g. '\n' to '\r\n' translation. Move this translation to rtems_putc(). Remove it from all the BSP_output_char implementations. Close #3122.

2017-06-20bsps: Improve interrupt vector enable/disable APISebastian Huber1-6/+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.

2016-07-17beagle: pwm polishingPunit Vara4-309/+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
2016-07-04Beaglebone: Update PWM driver imported from BBBIOPunit Vara3-385/+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.
2016-07-04Beaglebone: Add original BBBIO PWM driverPunit Vara2-0/+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.
2016-07-04bsps/arm: Change code to explicit selection of cache implementation for ARM ↵Pavel Pisa1-2/+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

2016-02-28am335x irq handling improvementMartin Galvan1-40/+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.

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.

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.

The extra includes in console_*.c are to solve a 'no previous prototype' warning. Solves #2212 in trac.
2014-12-05beagle bsp: disable watchdog on am335xBen Gras1-0/+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.

2014-11-03BSP for several Beagle productsBen Gras36-3221/+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>
