2019-02-14stm32mp1: update clock driverYann Gautier
Remove useless private structure in function prototypes. Add a reference counter on clocks. Prepare for future secured/shared/non-secured clocks.

2019-02-14stm32mp1: update I2C and PMIC driversYann Gautier
Regulator configuration at boot takes more information from DT. I2C configuration from DT is done in I2C driver. I2C driver manages more transfer modes. The min voltage of buck1 should also be increased to 1.2V, else the platform does not boot. Heavily modifies stm32_i2c.c since many functions move inside the source file to remove redundant declarations.

2019-02-11cpus: Add casts to all definitions in CPU headersAntonio Nino Diaz
There are some incorrect casts and some missing casts in the headers. This patch fixes the ones that were 64-bit or 32-bit wide wrongly and adds casts where they were missing. Note that none of the changes of the patch actually changes the values of the definitions. This patch is just for correctness.

2019-02-11cpus: Fix some incorrect definitions in CPU headersAntonio Nino Diaz
There are some values that should be 64-bit immediates but that resolve to 0 because the type of the value is 32-bit wide. This patch casts the expressions to 64-bit before the shift so that the definition has the correct value. The definitions are only used in assembly so far, so the code is not actually affected by this bug. The assembler treats all values as 64-bit values, so there are no overflows.

2019-02-08Make setjmp.h prototypes comply with the C standardAntonio Nino Diaz
Instead of having a custom implementation of setjmp() and longjmp() it is better to follow the C standard. The comments in setjmp.h are no longer needed as there are no deviations from the expected one, so they have been removed. All SDEI code that relied on them has been fixed to use the new function prototypes and structs.

2019-02-01Remove duplicated definitions of linker symbolsAntonio Nino Diaz
Many parts of the code were duplicating symbols that are defined in include/common/bl_common.h. It is better to only use the definitions in this header. As all the symbols refer to virtual addresses, they have to be uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

2019-01-31tlkd: support new TLK SMCsMihir Joshi
This patch adds support to handle following TLK SMCs: {TLK_SS_REGISTER_HANDLER, TLK_REGISTER_NS_DRAM_RANGES, TLK_SET_ROOT_OF_TRUST} These SMCs need to be supported in ATF in order to forward them to TLK. Otherwise, these functionalities won't work. Brief: TLK_SS_REGISTER_HANDLER: This SMC is issued by TLK Linux Driver to set up secure storage buffers. TLK_REGISTER_NS_DRAM_RANGES: Cboot performs this SMC during boot to pass NS memory ranges to TLK. TLK_SET_ROOT_OF_TRUST: Cboot performs this SMC during boot to pass Verified Boot parameters to TLK.

This reverts commit 2f370465241c ("Add support for the SMC Calling Convention 2.0"). SMCCC v2.0 is no longer required for SPM, and won't be needed in the future. Removing it makes the SMC handling code less complicated. The SPM implementation based on SPCI and SPRT was using it, but it has been adapted to SMCCC v1.0.

2019-01-30lib/xlat_tables: Add support for ARMv8.4-TTSTSathees Balya
ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the size of translation tables by increasing the maximum permitted value of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and VSTCR_EL2. This feature is supported in AArch64 state only. This patch adds support for this feature to both versions of the translation tables library. It also removes the static build time checks for virtual address space size checks to runtime assertions.

2019-01-23plat/arm: Save BL2 descriptors to reserved memory.Sathees Balya
On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory descriptors describing the list of executable images are created in BL2 R/W memory, which could be possibly corrupted later on by BL31/BL32 due to overlay. This patch creates a reserved location in SRAM for these descriptors and are copied over by BL2 before handing over to next BL image. Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR is enabled.

2019-01-22ti: k3: common: Add support for runtime detection of GICR base addressAndrew F. Davis
Valid addresses for GICR base are always a set calculable distance from the GICD and is based on the number of cores a given instance of GICv3 IP can support. The formula for the number of address bits is given by the ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to one for GICR instances. Holes in the GIC address space are also guaranteed to safely return 0 on reads. This allows us to support runtime detection of the GICR base address by starting from GIC base address plus BIT(18) and walking until the GICR ID register (IIDR) is detected. We stop searching after BIT(20) to prevent searching out into space if something goes wrong. This can be extended out if we ever have a device with 16 or more cores. Signed-off-by: Andrew F. Davis <afd@ti.com>

2019-01-15plat/arm: Fix header dependenciesAntonio Nino Diaz
From now on, platform_def.h must include any header with definitions that are platform-specific (like arm_def.h) and the included headers mustn't include back platform_def.h, and shouldn't be used by other files. Only platform_def.h should be included in other files. This will ensure that all needed definitions are present, rather than needing to include all the headers in all the definitions' headers just in case. This also prevents problems like cyclic dependencies. Change-Id: I9d3cf4d1de4b956fa035c79545222697acdaf5ca Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
