ARM: extend non-secure switch to also go into HYP mode

2013-10-03T19:28:55Z

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

ARM: trigger non-secure state switch during bootm execution

2013-10-03T19:28:46Z

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

ARM: use r9 for gd

2013-09-23T16:00:02Z

To be more EABI compliant and as a preparation for building with clang, use the platform-specific r9 register for gd instead of r8. note: The FIQ is not updated since it is not used in u-boot, and under discussion for the time being. The following checkpatch warning is ignored: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt Signed-off-by: Jeroen Hofstee cc: Albert ARIBAUD

ARM,relocate: do not use r9

2013-09-23T15:58:24Z

r9 is a platform-specific register in ARM EABI and not per definition a general purpose register. Do not use it while relocating so it can be used for gd. cc: Albert ARIBAUD Signed-off-by: Jeroen Hofstee

arm: spl: Do not set the stack pointer twice

2013-09-14T09:14:21Z

Because the stack pointer is already set in arch/arm/lib/crt0.S, we do not need to set it in arch/arm/lib/spl.c. Signed-off-by: Masahiro Yamada

arm: spl: For Falcon Mode, set a default machid of ~0

2013-08-15T22:38:35Z

With device trees, boards do not always set CONFIG_MACH_TYPE now, so we must not rely on this define being set. The kernel uses ~0 to see if we have a valid machine number or not, so set that as the default, invalid machine, id and only fix if CONFIG_MACH_TYPE is set.

ARM: move interrupt_init to before relocation

2013-07-25T06:14:28Z

interrupt_init also sets up the abort stack, but is not setup before relocation. So any aborts during relocation will hang and not print out any useful information. Fix this by moving the interrupt_init to after the stack setup in board_init_f. Signed-off-by: Rob Herring
