      drivers: mmc: Fix some issues with MMC stack · a468e756
      Tien Hock, Loh authored 
      

Some bugs in MMC stack needs to be fixed:
- scr cannot be local as this will cause cache issue when invalidating
after the read DMA transfer is completed
- ACMD41 needs to send voltage information in initialization, otherwise the
command is a query, thus will not initialize the controller
- when checking device state, retry until the retries counter goes to zero
before failing

      cpus: Add casts to all definitions in CPU headers · 1a74e4a8
      Antonio Nino Diaz authored 
      

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.

      cpus: Fix some incorrect definitions in CPU headers · a69817ed
      Antonio Nino Diaz authored 
      

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.

      Remove support for the SMC Calling Convention 2.0 · 0709055e
      Antonio Nino Diaz authored 
      This reverts commit 2f370465

 ("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.

      lib/xlat_tables: Add support for ARMv8.4-TTST · cedfa04b
      Sathees Balya authored 
      

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.

      plat/arm: Save BL2 descriptors to reserved memory. · 5b8d50e4
      Sathees Balya authored 
      

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.

Fixes ARM-Software/tf-issues#626

      ti: k3: common: Add support for runtime detection of GICR base address · b5443284
      Andrew F. Davis authored 
      

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.

      plat/arm: Fix header dependencies · 234bc7f8
      Antonio Nino Diaz authored 
      

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.

      Move BL1 and BL2 private defines to bl_common.h · c9f9d9ea

The definitions in bl1/bl1_private.h and bl2/bl2_private.h are useful for
platforms that may need to access them.
