| | * ARM: mxs: Setup stack in JTAG modeMarek Vasut2013-10-17-0/+2

This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change from 0x64656465 to 0x64646464 is to remove the weak pull enabled on DQS, nDQS lines. This pulls the differential signals in the same direction which is not intended. So disabling the weak pulls improves signal integrity. On the uEVM there are 4 DDR3 devices. The VREF for 2 of the devices is powered by the OMAP's VREF_CA_OUT pins. The VREF on the other 2 devices is powered by the OMAP's VREF_DQ_OUT pins. So the net effect here is that only half of the DDR3 devices were being supplied a VREF! This was clearly a mistake. The second change improves the robustness of the interface and was specifically seen to cure corruption observed at high temperatures on some boards. With the above two changes better memory stability was observed with extended temperature ranges around 100C. Signed-off-by: Sricharan R <r.sricharan@ti.com>

| * ARM: extend non-secure switch to also go into HYP modeAndre Przywara2013-10-03-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the KVM and XEN hypervisors to be usable, we need to enter the kernel in HYP mode. Now that we already are in non-secure state, HYP mode switching is within short reach. While doing the non-secure switch, we have to enable the HVC instruction and setup the HYP mode HVBAR (while still secure). The actual switch is done by dropping back from a HYP mode handler without actually leaving HYP mode, so we introduce a new handler routine in our new secure exception vector table. In the assembly switching routine we save and restore the banked LR and SP registers around the hypercall to do the actual HYP mode switch. The C routine first checks whether we are in HYP mode already and also whether the virtualization extensions are available. It also checks whether the HYP mode switch was finally successful. The bootm command part only calls the new function after the non-secure switch. Signed-off-by: Andre Przywara <andre.przywara@linaro.org>
| * ARM: add SMP support for non-secure switchAndre Przywara2013-10-03-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the non-secure switch is only done for the boot processor. To enable full SMP support, we have to switch all secondary cores into non-secure state also. So we add an entry point for secondary CPUs coming out of low-power state and make sure we put them into WFI again after having switched to non-secure state. For this we acknowledge and EOI the wake-up IPI, then go into WFI. Once being kicked out of it later, we sanity check that the start address has actually been changed (since another attempt to switch to non-secure would block the core) and jump to the new address. The actual CPU kick is done by sending an inter-processor interrupt via the GIC to all CPU interfaces except the requesting processor. The secondary cores will then setup their respective GIC CPU interface. While this approach is pretty universal across several ARMv7 boards, we make this function weak in case someone needs to tweak this for a specific board. The way of setting the secondary's start address is board specific, but mostly different only in the actual SMP pen address, so we also provide a weak default implementation and just depend on the proper address to be set in the config file.

| * ARM: add C function to switch to non-secure stateAndre Przywara2013-10-03-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The core specific part of the work is done in the assembly routine in nonsec_virt.S, introduced with the previous patch, but for the full glory we need to setup the GIC distributor interface once for the whole system, which is done in C here. The routine is placed in arch/arm/cpu/armv7 to allow easy access from other ARMv7 boards. We check the availability of the security extensions first. Since we need a safe way to access the GIC, we use the PERIPHBASE registers on Cortex-A15 and A7 CPUs and do some sanity checks. Boards not implementing the CBAR can override this value via a configuration file variable. Then we actually do the GIC enablement: a) enable the GIC distributor, both for non-secure and secure state (GICD_CTLR[1:0] = 11b) b) allow all interrupts to be handled from non-secure state (GICD_IGROUPRn = 0xFFFFFFFF) The core specific GIC setup is then done in the assembly routine.

| * ARM: add assembly routine to switch to non-secure stateAndre Przywara2013-10-03-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While actually switching to non-secure state is one thing, another part of this process is to make sure that we still have full access to the interrupt controller (GIC). The GIC is fully aware of secure vs. non-secure state, some registers are banked, others may be configured to be accessible from secure state only. To be as generic as possible, we get the GIC memory mapped address based on the PERIPHBASE value in the CBAR register. Since this register is not architecturally defined, we check the MIDR before to be from an A15 or A7. For CPUs not having the CBAR or boards with wrong information herein we allow providing the base address as a configuration variable. Now that we know the GIC address, we: a) allow private interrupts to be delivered to the core (GICD_IGROUPR0 = 0xFFFFFFFF) b) enable the CPU interface (GICC_CTLR[0] = 1) c) set the priority filter to allow non-secure interrupts (GICC_PMR = 0xFF) Also we allow access to all coprocessor interfaces from non-secure state by writing the appropriate bits in the NSACR register. The generic timer base frequency register is only accessible from secure state, so we have to program it now. Actually this should be done from primary firmware before, but some boards seems to omit this, so if needed we do this here with a board specific value. The Versatile Express board does not need this, so we remove the frequency from the configuration file here. After having switched to non-secure state, we also enable the non-secure GIC CPU interface, since this register is banked. Since we need to call this routine also directly from the smp_pen later (where we don't have any stack), we can only use caller saved registers r0-r3 and r12 to not mess with the compiler.

| | | | | | | | | | | | | | | | armv7.h contains some useful constants, but also C prototypes. To include it also in assembly files, protect the non-assembly part appropriately. Signed-off-by: Andre Przywara <andre.przywara@linaro.org>
