Gregory Nutt 21aef0dd68 drivers/*/Kconfig: Consolidate driver Kconfig Files.
This commit does two things:

1. First, it reorganizes the driver Kconfig files so that each is self contained.  Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig.  Now, all of the driver configuration is consolitated in the latter.

2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files.  This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well.

The nature of the introduced error was basically this:

- Nothing must intervene between the menuconfig selection and the following conditional configuration otpions.
- A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus.

This error was easy to make because the driver Kconfig files were not well modularized.  Making them fully self-contained should eliminate this kind of error in the future.

Guiding Li 8b92305265 This commit brings in the drivers needed to support OpenAMP. These changes were ported from https://github.com/FishsemiCode/nuttx. The current state: Most drivers do now compile but are not yet verfied.
This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository.

Squashed commit of the following:

    drivers/net:  Update Make.defs and Kconfig for OpenSDA support.
    Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c.  These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux.  Removed because we want to separate the activities.  We will just try to get the basic OpenAMP support in place for now.
    Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h.  These are specific to the Xiaomi application.

The pwm.h header was moved to include/nuttx/timers to keep consistency, so all files referencing it need to be updated. 2019-09-02 07:57:10 -06:00

Bob Feretich c6851201c0 This commit adds a new function arch_invalidate_dcache_by_addr(). It takes the same parameters as arch_invalidate_dcache(), but performs invalidation of only the lines in cache that need to be invalidated. This new function could be used as a a direct replacement for arch_invalidate_dcache().
The user of this invalidation are mmcsd_sdio currently.  The mmcsd_sdio driver makes calls for dcache invalidation through the chip specific architecture function SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache().

This commit includes additional changes to mmcsd_sdio.c.  I created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to invalidate store-into mode dcaches after the DMA transfer.  I have been using SDIO_DMADELYDINVLDT() for several weeks now and it has fixed the problems that I previously reported regarding non-cache aligned buffer invalidation errors (for my store-through dcache). However, it does not permit use of unaligned DMA buffers for store-into mode dcaches.

SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified all the stm32f7 chips to select it.

Jussi Kivilinna dffb8a67e3 Add entropy pool and strong random number generator
Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output.

Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.

Paul A. Patience d89765e1d0 spi: Fix Kconfig warning
This commit moves the ARCH_HAVE_SPI options outside the check
for SPI. Those options don't depend on SPI, and Kconfig files
in arch/ enable them even if SPI isn't enabled.

Sourcing the driver's Kconfig in drivers/Kconfig only if
support for the driver is enabled prevents us from defining
these ARCH_HAVE options in the driver's Kconfig. We should
probably remove the other checks in drivers/Kconfig and check
if the drivers are enabled only in their Kconfig.
