	203cdfe Browse files » Fix PSCI CPU ON race when setting state to ON_PENDING ... When a CPU is powered down using PSCI CPU OFF API, it disables its caches and updates its `aff_info_state` to OFF. The corresponding cache line is invalidated by the CPU so that the update will be observed by other CPUs running with caches enabled. There is a possibility that another CPU which has been trying to turn ON this CPU via PSCI CPU ON API, has already seen the update to `aff_info_state` and proceeds to update the state to ON_PENDING prior to the cache invalidation. This may result in the update of the state to ON_PENDING being discarded. This patch fixes this issue by making sure that the update of `aff_info_state` to ON_PENDING sticks by reading back the value after the cache flush and retrying it if not updated. The patch also adds a dsbish() to `psci_do_cpu_off()` to ensure ordering of the update to `aff_info_state` prior to cache line invalidation.

	d30ac1c Browse files » Use tf_printf() for debug logs from xlat_tables.c ... The debug prints used to debug translation table setup in xlat_tables.c used the `printf()` standard library function instead of the stack optimized `tf_printf()` API. DEBUG_XLAT_TABLE option was used to enable debug logs within xlat_tables.c and it configured a much larger stack size for the platform in case it was enabled. This patch modifies these debug prints within xlat_tables.c to use tf_printf() and modifies the format specifiers to be compatible with tf_printf(). The debug prints are now enabled if the VERBOSE prints are enabled in Trusted Firmware via LOG_LEVEL build option. The much larger stack size definition when DEBUG_XLAT_TABLE is defined is no longer required and the platform ports are modified to remove this stack size definition.

2016-01-29	ef7fb9e Browse files » Porting Guide: Clarify identity-mapping requirement ... The memory translation library in Trusted Firmware supports non-identity mappings for Physical to Virtual addresses since commit f984ce84ba. However, the porting guide hasn't been updated accordingly and still mandates the platform ports to use identity-mapped page tables for all addresses. This patch removes this out-dated information from the Porting Guide and clarifies in which circumstances non-identity mapping may safely be used.

2016-01-21	9400b40 Browse files » Disable PL011 UART before configuring it ... The PL011 TRM (ARM DDI 0183G) specifies that the UART must be disabled before any of the control registers are programmed. The PL011 driver included in TF does not disable the UART, so the initialization in BL2 and BL31 is violating this requirement (and potentially in BL1 if the UART is enabled after reset). This patch modifies the initialization function in the PL011 console driver to disable the UART before programming the control registers. Register clobber list and documentation updated.

2016-01-20	0e5dcdd Browse files » ARM plat: add build option to unlock access to non-secure timer ... Currently, Trusted Firmware on ARM platforms unlocks access to the timer frame registers that will be used by the Non-Secure world. This unlock operation should be done by the Non-Secure software itself, instead of relying on secure firmware settings. This patch adds a new ARM specific build option 'ARM_CONFIG_CNTACR' to unlock access to the timer frame by setting the corresponding bits in the CNTACR<N> register. The frame id <N> is defined by 'PLAT_ARM_NSTIMER_FRAME_ID'. Default value is true (unlock timer access). Documentation updated accordingly.
