libs/libc/pthread/pthread_spinlock.c:  Resolve several TODO issues by accessing up_testset() via the boardctl() interface rather than attempting to call it directly.

    configs/boardctl.c, include/sys/boardctl.h:  Add access to architecture-specific up_testset() via boardctl().

    arch/Kconfig's, sched/Kconfig, and include/nuttx/spinlock.h:  Spinlocks are not available unless the architecture supports the up_testset() operation.

4c601faf6f Brings in initial WIP support for the STML0. This initial commit is in pretty bad shape and, hence it it marked EXPERIMENTAL."
Squashed commit of the following:

    arch/arm/src/stm32f0l0:  Various changes for a clean compilation.  Still does not compile correctly due to missing FLASH latency definitions.

    arch/arm/src/stm32f0l0/hardware:  Add framework for the STM32 L0.  Currently set to same as the STM32F0.

    arch/arm/src/stm32f0l0/hardware:  Very fragmentary FLASH header register definitions for the STM32 L0.

    arch/arm/src/stm32f0l0:  Bring in DMA v1.  Cannot possibly be functionaly yet due to the limited number for M0 interrupts.

    arch/arm/src/stm32f0l0:  Add STM32 F0/L0 LSE and backup power domain controls.

    arch/arm/src/stm32f0l0/hardware/stm32l0_pwr.h:  Add STM32L0 PWR header file.

    arch/arm/include/stm32f0l0/chip.h: Clean up WIP chip header file.

    arch/arm/include/stm32f0l0/chip.h: WIP.

    arm/src/stm32f0l0: Resolve some small differences between F0 and L0 GPIO pin options.

    arch/arm/src/stm32f0l0: Better integrate STM32L0 header files.

    nuttx/arch/arm/include/stm32f0l0:  Add STM32L0 IRQ number definition file.

    arch/arm/src/stm32f0l0:  Add STM32L0 RCC driver.

    arch/arm/src/stm32f0l0/hardware:  Adds basic STM32L0 header files.

arch/arm/src/stm32f0l0:  Some fixes for a clean build.  Still have a problem with lots of error messages coming from kconfig-mconf, but the configuation looks fine.  Sometimes kconfig errors are difficult to spot.  I would appreciate it anyone can spot the issue.

    arch/arm/src/stm32f0l0/hardware:  Rename the chip directory to hardware.  This will hopefully eliminate some problems that I have seen with the chip include paths not being unique in more complex configuartions.

    configs/nucleo-f072rb, configs/nucleo-f091rc, configs/stm32f051-discovery, and configs/stm32f072-discovery:  Update for all of the naming changes made in arch/arm/src/stm32f0l0

    arch/arm/include/stm32f0l0:  Rename stm32f0 to stm32f0l0 to make a speace for STM32 L0.  Rename files, functions and defines, removeing the f0_ from the names in order to make them MCU agnostic.

09ccd43d61 arch/arm/include/armv7-m, arch/arm/include/armv7-m, arch/arm/include/stm32f7: Add a configuration to enable workaround for r0p1 Errata 837070: Increasing priority usingwrite to BASEPRI does not take effect immediately.
This update is required to be serialized to the instruction stream meaning that after this update completes, it takes effect immediately and no exceptions of lower priority than the new boosted priority can pre-empt execution.  Because of this erratum, the priority boosting does not take place immediately, allowing the instruction after the MSR to be interrupted by an exception of lower priority than the new boosted priority. This effect is only limited to the next instruction. Subsequent instructions are guaranteed to see the new boosted priority.

This was raised in Bitbucket issue 113 from Vadzim Dambrouski.

    Embarassingly trivial change left in compiler.
    arch/arm/src/imxrt:  Finishes i.MX RT1050 LPUART register definition header file.
    arch/arm/src/imxrt:  Beginning of an i.MX RT1050 LPUART register definition header file.
    Some trivial things

  Author: Gregory Nutt <gnutt@nuttx.org>
    Trivial update to README.
    arch/arm/src/imxrt:  The i.MX Rt implements 4 bits of interrupt priority, not two.  Thanks, Janne.
    arch/arm/src/imxrt:  Fix some initial compile issues.  Still a long way from complete, but there is a buildable environment now for the imxrt1050-evk.
    configs/imxrt1050-evk:  Add an initial NSH configuration for testing.
    configs/Kconfig:  Hook the i.MX RT 1050 board configuration into the NuttX configuration system.
    configs/imxrt_evk:  Add the framework for i.MX RT 1050 board support.
    arch/arm/src/imxrt:  Bring in a few more files from LPC54xxx.
    arch/arm/src/imxrt:  Bring in imxrt_clrpend() from the LPC54xxx.
    arch/arm/src/imxrt:  Bring in Cortex-M7 SysTick setup from the SAMv7.
    arch/arm/src/imxrt:  Add a few easy files.
    arch/arm/src/imxrt/chip:  Add memory map header files.
    arch/arm/src/imxrt:  A few basic files to start the port to the i.MX RT 1050.

8bc90a1899 This adds basic architectural support for the LPC546xx family and includes support for the LPCXpresso-LPC54628 board. The basic NSH port is almost complete... still lacking GPIO support and LED support. There are still no significant drivers available.
Squashed commit of the following:

    arch/arm/src/lpc54xx:  Finish off some missing logic.  Complete now execpt for GPIO and LED support.
    arch/arm/src/lpc54xx:  Add lpc54_clrpend.c
    arch/arm/src/lpc54xx:  Serial driver is complete and compiles.
    arch/arm/src/lpc54xx:  Add beginning of a serial driver (still missing some logic)
    arch/arm/src/lpc54xx:  Fleshes out low level USART intialization.
    arch/arm/src/lpc546xx/Kconfig: Add hooks to integrate with common seril upper half.
    arch/arm/src/lpc54xx:  Beginning of USART console support.
    arch/arm/src/lpc54xx: Completes very basic clock configuration.
    arch/arm/src/lpc54xx:  Add clocking logic (still not complete)
    arch/arm/src/lpc54xx:  Beginning of PLL configuration logic.
    arch/arm/src/lpc54xx:  Fix a few things from first compile attempt.  Compilation cannot work until I at least finish the clock configuration logic.
    arch/arm/src/lpc54xx: Addes some SysTick logic.
    arch/arm/src/lpc54xx:  Completes basic startup logic (sans clock configuration) and interrupt configuration.
     arch/arm/src/lpc54xx:  Add generic ARMv7-M start-up logic (needs LPC54628 customizations); add emtpy file that will eventually hold the clock configuration logic.
    arch/arm/src/lpc54xx:  Add (incomplete) SYSCON register definition header file.
    arch/arm/src/lpc54xx:  Add FLEXCOMM header file.
    arch/arm/src/lpc54xx:  Bring in tickless clock logic from LPC43; configs/lpcxpresso-lpc54628: mount procfs if enabled.
    arch/arm/src/lpc54xx: Add RIT clock definitions; add SysTick initialization (not finished)
    LPC54xx and LPCXpresso-LPC54628: add more boilerplate files and stubbed out files.
    arch/arm/src/lpc54xx:  Add (incomplete) USART header file.
    Add another condition to a Kconfig; refresh a defconfig.
    arch/arm/src/lpc54xx/chip: Add LPC54628 memory map header files.
    configs/lpcxpresso-lpc54628:  Add basic build files for the LPCXpresso-LPC54628

f3b37e5da3 fs/procfs/fs_procfsprogrem: Add /proc/progmem. This is an alternative way to get the information that was previoulsy available in apps/system/free. apps/system/free was removed beause it made illegal calls into the OS violating the portable interface. This new procfs entry provides the same information with no such violation. 2017-11-13 09:08:39 -06:00

270aa2848a Squashed commit of the following:
BCM2708:  Add enough infrastructrue (more stubs) to get a clean compilation of the Pi Zero configuration (with many undefined things at link time).

    BCM2708:  Add basic interrupt handling logic

    BCM2708: Add interrupt register definitions.

    BCM2708:  Add irq.h header file

    BCM2708/Pi zero:  bcm_boot.c and bcm_memorymap.h now compile.  Added pizero linker script.

    BCM2708/Pi Zero:  Add Make.defs needed to build.

    arch/arm/include/bcm2708, arch/arm/src/bcm2708, configs/pizero:  Add some basic build and configuration logic.

    configs/pizero:  Add some basic structure of the Rasperry Pi Zero port.

    Created directory configs/pizero.  Nothing there now but a README.txt file.

    Add initial boot.c and memorymap.c files

    Pizero GPIO registers
    * Initial commit to add GPIO definitions
    * Add remaining GPIO registers definition
    Alan Carvalho de Assis <acassis@gmail.com>

    BCM2708 memory map:  Add VBASE defintions; fix VCSDRAM address per Alan; move all virtual address to the bottom of the file to avoid confusion -- top is all physical address; bottom is all veritural address.

    Add initial memory map to BCM2708/BCM2835
