Rajan Vaja cc974c52c2 zynqmp: pm_service: Support multiple SDIO modes
Existing database allows to set only single mode for SDIO.
SDIO can have different groups (8 bit, 4 bit and 1 bit).
As there is only single SDIO group in each pin, it is not
 possible to use different mode groups for SDIO.

Extend database in generic way to allow multiuple function
groups in single pin. Add different SDIO groups to pins and
create separate functions for each modes.

Rajan Vaja bd99265b06 zynqmp: pm: Add APIs for pin control queries
Add pin control APIs which driver can use to query
pin information from firmware. Using these APIs,
driver do not need to maintain hard-coded pin database.

Major changes in patch are:
- Add pin database with pins, functions and function groups
  information
- Implement APIs for pin information queries
- Update pin control APIs for get/set functions to use new
  pin control database. Remove pin database which was added
  earlier.

Douglas Raillard 32f0d3c6c3 Replace some memset call by zeromem
Replace all use of memset by zeromem when zeroing moderately-sized
structure by applying the following transformation:
memset(x, 0, sizeof(x)) => zeromem(x, sizeof(x))

As the Trusted Firmware is compiled with -ffreestanding, it forbids the
compiler from using __builtin_memset and forces it to generate calls to
the slow memset implementation. Zeromem is a near drop in replacement
for this use case, with a more efficient implementation on both AArch32
and AArch64.

We have lots of duplicated defines (and comment blocks too).
Move them to include/plat/common/common_def.h.

While we are here, suffix the end address with _END instead of

real end address.

Masahiro Yamada ecdc898da3 Use *_END instead of *_LIMIT for linker derived end addresses
The usage of _LIMIT seems odd here, so rename as follows:
  BL_CODE_LIMIT     --> BL_CODE_END
  BL_RO_DATA_LIMIT  --> BL_RO_DATA_END
  BL1_CODE_LIMIT    --> BL1_CODE_END
  BL1_RO_DATA_LIMIT --> BL1_RO_DATA_END

Basically, we want to use _LIMIT and _END properly as follows:
  *_SIZE + *_MAX_SIZE = *_LIMIT
  *_SIZE + *_SIZE     = *_END

The _LIMIT is generally defined by platform_def.h to indicate the
platform-dependent memory constraint.  So, its typical usage is
  ASSERT(. <= BL31_LIMIT, "BL31 image has exceeded its limit.")
in a linker script.

On the other hand, _END is used to indicate the end address of the
compiled image, i.e. we do not know it until the image is linked.

Here, all of these macros belong to the latter, so should be
suffixed with _END.

Masahiro Yamada 34071d6aec zynqmp: add "override" directive to mandatory options
The platform.mk sets build options required for ZynqMP, but users
can still change them from the command line, like:

  make PLAT=zynqmp RESET_TO_BL31=0 CROSS_COMPILE=...

Then, the makefile shows an error message in that case:
  Using BL31 as the reset vector is only one option supported on ZynqMP.
  Please set RESET_TO_BL31 to 1.

If the option is not user-configurable, the makefile can specify
"override" to prevent users from changing it.  We do not need the
error message for the case that never happens.

Likewise, ENABLE_PLAT_COMPAT := 0 and PROGRAMMABLE_RESET_ADDRESS := 1
are mandatory to avoid build error.

Jeenu Viswambharan a806dad58c Define and use no_ret macro where no return is expected
There are many instances in ARM Trusted Firmware where control is
transferred to functions from which return isn't expected. Such jumps
are made using 'bl' instruction to provide the callee with the location
from which it was jumped to. Additionally, debuggers infer the caller by
examining where 'lr' register points to. If a 'bl' of the nature
described above falls at the end of an assembly function, 'lr' will be
left pointing to a location outside of the function range. This misleads
the debugger back trace.

This patch defines a 'no_ret' macro to be used when jumping to functions
from which return isn't expected. The macro ensures to use 'bl'
instruction for the jump, and also, for debug builds, places a 'nop'
instruction immediately thereafter (unless instructed otherwise) so as
to leave 'lr' pointing within the function range.

Arm provided error injection support. To enable this error injection,
we need to set L2DEIEN in L2ACTLR_EL1 register and L1DEIEN in
CPUACTLR_EL1 register.

This is needed for our cortexa53 edac linux driver testing.
These registers need write access from non secure EL1 i.e linux
at the time of setting the above bits.

Sandrine Bailleux 0af559a833 ARM platforms: Add support for SEPARATE_CODE_AND_RODATA
The arm_setup_page_tables() function used to expect a single set of
addresses defining the extents of the whole read-only section, code
and read-only data mixed up, which was mapped as executable.

This patch changes this behaviour. arm_setup_page_tables() now
expects 2 separate sets of addresses:

 - the extents of the code section;
 - the extents of the read-only data section.

The code is mapped as executable, whereas the data is mapped as
execute-never. New #defines have been introduced to identify the
extents of the code and the read-only data section. Given that
all BL images except BL1 share the same memory layout and linker
script structure, these #defines are common across these images.
The slight memory layout differences in BL1 have been handled by
providing values specific to BL1.

Note that this patch also affects the Xilinx platform port, which
uses the arm_setup_page_tables() function. It has been updated
accordingly, such that the memory mappings on this platform are
unchanged. This is achieved by passing null values as the extents
of the read-only data section so that it is ignored. As a result,
the whole read-only section is still mapped as executable.

Fixes ARM-software/tf-issues#85

Sandrine Bailleux ed81f3ebbf Introduce utils.h header file
This patch introduces a new header file: include/lib/utils.h.
Its purpose is to provide generic macros and helper functions that
are independent of any BL image, architecture, platform and even
not specific to Trusted Firmware.

For now, it contains only 2 macros: ARRAY_SIZE() and
IS_POWER_OF_TWO(). These were previously defined in bl_common.h and
xlat_tables.c respectively.

bl_common.h includes utils.h to retain compatibility for platforms
that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream
platform ports that use this macro have been updated to include
utils.h.

Sandrine Bailleux b5fa6563e6 Introduce arm_setup_page_tables() function
This patch introduces the arm_setup_page_tables() function to
set up page tables on ARM platforms. It replaces the
arm_configure_mmu_elx() functions and does the same thing except
that it doesn't enable the MMU at the end. The idea is to reduce
the amount of per-EL code that is generated by the C preprocessor
by splitting the memory regions definitions and page tables creation
(which is generic) from the MMU enablement (which is the only per-EL
configuration).

As a consequence, the call to the enable_mmu_elx() function has been
moved up into the plat_arch_setup() hook. Any other ARM standard
platforms that use the functions `arm_configure_mmu_elx()` must be
updated.
