* ARM: extend non-secure switch to also go into HYP modeAndre Przywara2013-10-03-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | 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: 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>

* bootm: Clean up bootz_setup() functionSimon Glass2013-07-10-6/+8
| | | | | | | | | 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 <sjg@chromium.org>
* arm: Implement the 'fake' go commandSimon Glass2013-06-26-9/+18

* arm: Use image_setup_linux() instead of local codeSimon Glass2013-05-14-56/+1
| | | | | | | | 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 <sjg@chromium.org>
* arm: Refactor bootm to reduce #ifdefsSimon Glass2013-05-14-64/+20
| | | | | | | | 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 <sjg@chromium.org>

* | ARM: increase lmb stack space reservation to 4KBRob Herring2012-10-04-2/+2
|/ | | | | | | | | | The bootm initrd image copy to ram can collide with the stack in cases where the print buffer size is large (i.e. 1K). The result is intermittent initrd decompression errors depending on the initrd size MOD 4KB since the initrd start address is 4KB aligned.

* bootstage: arm: Add bootstage calls in board and bootmSimon Glass2012-03-18-0/+4
| | | | | | | | | | | Add calls to bootstage before and after relocation, and just before jumping to the OS. The idea here is you can call bootstage_report() to get a report. Additionally, if you define CONFIG_BOOTSTAGE_REPORT then a report is printed automatically by U-Boot just before jumping to the kernel. Signed-off-by: Simon Glass <sjg@chromium.org>

* Respect memreserve regions specified in the device treeGrant Likely2011-04-25-0/+2
| | | | | | | | If a regions is reserved in the fdt, then it should not be used. Add the memreserve regions to the lmb so that u-boot doesn't use them to store the initrd. Signed-off-by: Grant Likely <grant.likely@linaro.org>
* Stop passing around bootmem_base value.Grant Likely2011-04-25-2/+1
| | | | | | | | | | For the calls to boot_relocate_fdt(), boot_get_cmdline(), and boot_get_kbd(), the value of bootmem_base is always obtained by calling getenv_bootm_low(). Since the value always comes from the same source, the calling signature for those functions can be simplified by making them call getenv_bootm_low() directly.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...
