2017-02-28target-arm: Implement BCM2835 hardware RNGMarcin Chojnacki
Recent vanilla Raspberry Pi kernels started to make use of the hardware random number generator in BCM2835 SoC. As a result, those kernels wouldn't work anymore under QEMU but rather just freeze during the boot process. This patch implements a trivial BCM2835 compatible RNG, and adds it as a peripheral to BCM2835 platform, which allows to boot a vanilla Raspberry Pi kernel under Qemu. Changes since v1: * Prevented guest from writing [31..20] bits in rng_status * Removed redundant minimum_version_id_old * Added field entries for the state * Changed realize function to reset Signed-off-by: Marcin Chojnacki <marcinch7@gmail.com> Message-id: 20170210210857.47893-1-marcinch7@gmail.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2017-02-07hw/misc: New "unimplemented" sysbus devicePeter Maydell
Create a new "unimplemented" sysbus device, which simply accepts all read and write accesses, and implements them as read-as-zero, write-ignored, with logging of the access as LOG_UNIMP. This is useful for stubbing out bits of an SoC or board model which haven't been written yet.

2016-09-06ast2400: add a memory controller device modelCédric Le Goater
The uboot in the previous release of the SDK was using a hardcoded value for memory size. This is not true anymore, the value is now retrieved from the memory controller. Below is a model for this device, only supporting unlock and configuration. Without it, we endup running a guest with 64MB, which is a bit low nowdays. It uses a 'silicon-rev' property and ram_size to build a default value. Some bits should be linked to SCU strapping registers but it seems a bit complex to add for the current need. The model is ready for the AST2500 SOC. Signed-off-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
