2013-11-27Unmask SError and Debug exceptions.Sandrine Bailleux
Any asynchronous exception caused by the firmware should be handled in the firmware itself. For this reason, unmask SError exceptions (and Debug ones as well) on all boot paths. Also route external abort and SError interrupts to EL3, otherwise they will target EL1. Change-Id: I9c191d2d0dcfef85f265641c8460dfbb4d112092
2013-11-27fvp: Remove unnecessary initializersSandrine Bailleux
Global and static variables are expected to be initialised to zero by default. This is specified by the C99 standard. This patch removes some unnecessary initialisations of such variables. It fixes a compilation warning at the same time: plat/fvp/bl31_plat_setup.c:82:3: warning: missing braces around initializer [-Wmissing-braces] section("tzfw_coherent_mem"))) = {0}; ^ plat/fvp/bl31_plat_setup.c:82:3: warning: (near initialization for ‘ns_entry_info[0]’) [-Wmissing-braces] Note that GCC should not have emitted this warning message in the first place. The C Standard permits braces to be elided around subaggregate initializers. See this GCC bug report: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119 Change-Id: I13cb0c344feb9803bca8819f976377741fa6bc35

2013-11-27Move generic architectural setup out of blx_plat_arch_setup().Sandrine Bailleux
blx_plat_arch_setup() should only perform platform-specific architectural setup, e.g. enabling the MMU. This patch moves generic architectural setup code out of blx_plat_arch_setup(). Change-Id: I4ccf56b8c4a2fa84909817779a2d97a14aaafab6

2013-11-14Add GICv3 ITS to FDTsHarry Liebel
- The interrupt addresses need to be updated to work. Change-Id: Icdd00177095ae9e4eb7b13718762f92e29b1465c
2013-11-14Do not enable CCI on Foundation FVPHarry Liebel
- The Foundation FVP only has one cluster and does not have CCI. Change-Id: If91e81ff72c52e448150089c4cfea3e4d6ae1232
2013-11-14FDTs for v5.2 Foundation modelHarry Liebel
- The Foundation FVP is a cut down version of the Base FVP and as such lacks some components. - Three FDTs are provided. fvp-foundation-gicv2legacy-psci: Use this when setting the Foundation FVP to use GICv2. In this mode the GIC is located at the VE location, as described in the VE platform memory map. fvp-foundation-gicv3-psci : Use this when setting the Foundation FVP to use GICv3. In this mode the GIC is located at the Base location, as described in the Base platform memory map. fvp-foundation-gicv2-psci : Use this when setting the Foundation FVP to use GICv3, but Linux is expected to use GICv2 emulation mode. In this mode the GIC is located at the Base location, but the GICv3 is used in GICv2 emulation mode. Change-Id: I9d69bcef35c64cc8f16550efe077f578e55aaae5
