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

bootm: Clean up bootz_setup() function

2013-07-10T13:15:14Z

This function has no prototype in the headers and passes void * around, thus requiring several casts. Tidy this up. - Add new patch to clean up bootz_setup() function Signed-off-by: Simon Glass

arm: Implement the 'fake' go command

2013-06-26T14:18:56Z

Implement this feature on ARM for tracing. It would be nice to have generic bootm support so that it is easily implemented on any arch. Signed-off-by: Simon Glass Acked-by: Albert ARIBAUD

arm: Use image_setup_linux() instead of local code

2013-05-14T19:37:25Z

Use the common FDT setup function that is now available in image. Move the FDT-specific code to a new bootm-fdt.c and remove unused headers from bootm.c. Signed-off-by: Simon Glass

arm: Refactor bootm to reduce #ifdefs

2013-05-14T19:37:25Z

With fewer #ifdefs the code is more readable and more of the code is compiled for all boards. Add defines in the header file to control what features are enabled, and then use if() instead of #ifdef. Signed-off-by: Simon Glass

treewide: include libfdt_env.h before fdt.h

2013-02-08T01:38:55Z

and, if including libfdt.h which includes libfdt_env.h in the correct order, don't include fdt.h before libfdt.h. this is needed to get the fdt type definitions set from the project environment before fdt.h uses them. Signed-off-by: Kim Phillips Cc: Jerry Van Baren
