2019-05-02dev-arm: Read correct version of ICC_BPR registerGiacomo Travaglini
Some methods like groupPriorityMask check for the value of binary point registers. Those registers have a minimum value. Writing to those register is taking this into account, but the problem with the minimum value arises when the value is checked before sw is writing to them. In this case the minimum value won't be considered if the read is directly forwarded to the ISA class.

2019-05-02dev-arm: Add several LPI methods in Gicv3RedistributorGiacomo Travaglini
Refactoring the existing in code in smaller methods will be crucial when adding the ITS module, which is a client for the redistributor class and which will require it to take different actions depending on the command it receives from software. List of methods: * read/writeEntryLPI Reading/Writing a byte from the LPI pending table * isPendingLPI Checks if the pINTID LPI is set. Knowing if an LPI is set is needed by the MOVI command, which is transfering the pending state from one redistributor to the other only if the LPI is pending.

2018-10-08dev, arm: remove the RealViewEB platformCiro Santilli
This is an old platform, and we haven't had official Linux kernel configs for it in a while, so we've decided to deprecate it. Furthermore, trying to use it fails with: object 'RealViewEB' has no attribute 'pci_host' and the last commit in the class happened two years ago, which indicates that no one has been using it.

2018-10-01dev-arm: Fix GICv2 cpu interrupt enable flagGiacomo Travaglini
Read/WriteCpu methods in the GICv2 are accessing the GICC_CTRL register as if writing any non-zero value to the register will enable IRQ signaling to the CPU. Instead, only the 2 least significant bits control group0/group1 enablement. This patch is renaming GICC_CTRL underlying data buffer from cpuEnabled to cpuControl and it is making it an array of uint32_t instead of bool. cpuEnabled now becomes a method and checks if GICC_CTRL.EnableGrp0 or GICC_CTRL.EnableGrp0 are set.
