* ARM: trigger non-secure state switch during bootm executionAndre Przywara2013-10-03-0/+13
| | | | | | | | | To actually trigger the non-secure switch we just implemented, call the switching routine from within the bootm command implementation. This way we automatically enable this feature without further user intervention. Signed-off-by: Andre Przywara <andre.przywara@linaro.org>
* ARM: add C function to switch to non-secure stateAndre Przywara2013-10-03-0/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Przywara2013-10-03-2/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: add secure monitor handler to switch to non-secure stateAndre Przywara2013-10-03-0/+57
| | | | | | | | | | | | | | A prerequisite for using virtualization is to be in HYP mode, which requires the CPU to be in non-secure state first. Add a new file in arch/arm/cpu/armv7 to hold a monitor handler routine which switches the CPU to non-secure state by setting the NS and associated bits. According to the ARM architecture reference manual this should not be done in SVC mode, so we have to setup a SMC handler for this. We create a new vector table to avoid interference with other boards. The MVBAR register will be programmed later just before the smc call. Signed-off-by: Andre Przywara <andre.przywara@linaro.org>

In all cases, we see if we can rely on the efuse_sma register to tell us the maximum speed. In the case of Beaglebone White, we need to make sure we are on AC power, and are on later than rev A1, and then we can ramp up to the PG1.0 maximum of 720Mhz. In the case of Beaglebone Black, we are either on PG2.0 that supports 1GHz or PG2.1. As PG2.0 may or may not have efuse_sma set, we cannot rely on this probe. In the case of the GP EVM, EVM SK and IDK we need to rely on the efuse_sma if we are on PG2.1, and the defaults for PG1.0/2.0. Signed-off-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with PG2.1 we have a register in the CONTROL_MODULE that is set with the package type and maximum supported frequency. Add this, and the relevant mask/values. Signed-off-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to allow for a further call-out in spl_board_init. Call this am33xx_spl_board_init and add a __weak version. This function may be used to scale the MPU frequency up, depending on board needs. Signed-off-by: Tom Rini <trini@ti.com>
