Add support for STMicroelectronics STM32 random number generator. The config value defaults to N, reflecting the fact that STM32 is a very low resource microcontroller platform and unlikely to be targeted by any "grown up" defconfigs.

In April 2009, commit d4056405 ("Driver Core: misc: add node name support for misc devices.") inadvertently changed the device node name from /dev/hw_random to /dev/hwrng. Since 6 years has passed since the change it seems unpractical to change it back, as this node name is probably considered ABI by now. So instead, we'll just change the Kconfig help to match the current situation. NB: It looks like rng-tools have already been updated.

The driver for the "Picochip picoXcell true random number generator" was added in v2.6.39. Its Kconfig symbol has always depended on PICOXCELL_PC3X3. But that Kconfig symbol has never been part of the tree. This means this driver has never been buildable. Let's remove it. It can be re-added if its dependencies are actually part of the tree.

HW_RANDOM_ATMEL should not only default to ARCH_AT91, it should depend on it. This driver is useless on other architectures. Likewise, HW_RANDOM_EXYNOS should depend on ARCH_EXYNOS, as it it useless on other architectures. Also set the default to HW_RANDOM for the few architecture-specific drivers which didn't have it yet, for consistency.

To handle these differences, a platform_data structure is defined and contains routine pointers, register offsets.

由 Linus Walleij 提交于
This moves the MTU timer driver from arch/arm/plat-nomadik to drivers/clocksource and moves the header file to the platform_data directory. As this moves the last file being compiled to an object out of arch/arm/plat-nomadik, we have to "turn off the light" and delete the plat-nomadik directory, because it is not allowed to have an empty Makefile in a plat-* directory. This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory. After this all the Ux500 and Nomadik device drivers live outside of the arch/arm hierarchy.

Some hardware platforms, the TS-7800[1] is one for example, can supply the kernel with an entropy source, albeit a slow one for TS-7800 users, by just reading a particular IO address. This source must not be read above a certain rate otherwise the quality suffers. The driver is then hooked into by calling platform_device_(register|add|del) passing a structure similar to: ------ static struct timeriomem_rng_data ts78xx_ts_rng_data = { .address = (u32 *__iomem) TS_RNG, .period = 1000000, /* one second */ }; static struct platform_device ts78xx_ts_rng_device = { .name = "timeriomem_rng", .id = -1, .dev = { .platform_data = &ts78xx_ts_rng_data, }, .num_resources = 0, }; ------ [1] http://www.embeddedarm.com/products/board-detail.php?product=TS-7800Signed-off-by: NAlexander Clouter <alex@digriz.org.uk> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Note that by itself, having a "hardware" random generator does very little: you should probably run "rngd" in your guest to feed this into the kernel entropy pool. Included: virtio_rng: dont use vmalloced addresses for virtio If virtio_rng is build as a module, random_data is an address in vmalloc space. As virtio expects guest real addresses, this can cause any kind of funny behaviour, so lets allocate random_data dynamically with kmalloc.
