ARM: create .secure_stack section only for PSCI

2016-10-14T20:18:34Z

Jon Master reports that QEMU refuses to load a U-Boot image built with CONFIG_ARMV7_NONSEC, but without CONFIG_ARMV7_PSCI since commit 5a3aae68c74e ("ARM: armv7: guard memory reserve for PSCI with #ifdef CONFIG_ARMV7_PSCI"). It looks like only PSCI that needs the Secure stack, so move the #ifdef to guard the whole of .secure_stack allocation in order not to create the empty section.

ARM: AM437X: Add Silicon ID support

2016-10-08T13:33:36Z

Add silicon ID code for AM437x silicon. This can be used to print the cpu info using CONFIG_DISPLAY_CPUINFO. Also printing "CPU :" along with cpu name in order to be consistent with other OMAP platforms. Reviewed-by: Tom Rini Signed-off-by: Lokesh Vutla

ARM: vf610: use strcpy for soc environment variable

2016-10-07T13:56:52Z

To create the soc environment variable we concatenate two strings on the stack. So far, strcat has been used for the first string as well as for the second string. Since the variable on the stack is not initialized, the first strcat may not start using the first entry in the character array. This then could lead to an buffer overflow on the stack.

ARM: OMAP5+: Override switch_to_hypervisor function

2016-10-07T00:58:16Z

Override the switch_to_hypervisor function to switch cpu to hypervisor mode using the available ROM code hook early in the boot phase before the boot loader checks for HYP mode.

ARM: Introduce function to switch to hypervisor mode

2016-10-07T00:58:16Z

On some of the SoCs one cannot enable hypervisor mode directly from the u-boot because the ROM code puts the chip to supervisor mode after it jumps to boot loader. Hence introduce a weak function which can be overridden based on the SoC type and switch to hypervisor mode in a custom way.

omap: Set appropriate cache configuration for LPAE and non-LAPE cases

2016-10-07T00:57:44Z

Cache configuration methods is different for LPAE and non-LPAE cases. Hence the bits and the interpretaion is different for two cases. In case of non-LPAE mode short descriptor format is used and we need to set Cache and Buffer bits. In the case of LPAE the cache configuration happens via MAIR0 lookup.

omap: Remove hardcoding of mmu section shift to 20

2016-10-07T00:57:43Z

As of now the mmu section shift is hardcoded to 20 but with LPAE coming into picture this can be different. Hence replacing 20 with MMU_SECTION_SHIFT macro. Signed-off-by: Keerthy Reviewed-by: Tom Rini

ARMv8/sec-firmware: fix a compile error

When enabled sec firmware framework, but lack of definition of the marco SEC_FIRMWARE_FIT_IMAGE, SEC_FIRMEWARE_FIT_CNF_NAME and SEC_FIRMWARE_TARGET_EL, there will be some build errors, so give a default definition. Signed-off-by: Hou Zhiqiang
