Varun Wadekar e44f86ef2b Tegra: remove weakly defined PSCI platform handlers
This patch removes all the weakly defined PSCI handlers defined
per-platform, to improve code coverage numbers and reduce MISRA
defects.

Varun Wadekar 5f1803f90f Tegra: per-SoC DRAM base values
Tegra194 supports upto 64GB of DRAM, whereas the previous SoCs support
upto 32GB DRAM. This patch moves the common DRAM base/end macros to
individual Tegra SoC headers to fix this anomaly.

Varun Wadekar ceb12020fb Tegra194: organize the memory/mmio map to make it linear
This patch organizes the platform memory/mmio map, so that the base
addresses for the apertures line up in ascending order. This makes
it easier for the xlat_tables_v2 library to create mappings for each
mmap_add_region call.

Steven Kao 33a8ba6a38 Tegra194: support for boot params wider than 32-bits
The previous bootloader is not able to pass boot params wider than
32-bits due to an oversight in the scratch register being used. A
new secure scratch register #75 has been assigned to pass the higher
bits.

This patch adds support to parse the higher bits from scratch #75
and use them in calculating the base address for the location of
the boot params.

Scratch #75 format
====================
31:16 - bl31_plat_params high address
15:0 - bl31_params high address

Puneet Saxena 1296da6d85 Tegra194: memctrl: update mss reprogramming as HW PROD settings
Memory clients are divided in to ISO/NonISO/Order/Unordered/Low
BW/High BW. Based on the client types, HW team recommends, different
memory ordering settings, IO coherency settings and SMMU register settings
for optimized performance of the MC clients.

For example ordered ISO clients should be set as strongly ordered and
should bypass SCF and directly access MC hence set as
FORCE_NON_COHERENT. Like this there are multiple recommendations
for all of the MC clients.

This change sets all these MC registers as per HW spec file.

Force memory transactions from viw and viflar/w as non-coherent from

path and stage-2 smmu mappings won't mark transactions as non-coherent.

Varun Wadekar 117dbe6ce9 Tegra: introduce plat_enable_console()
This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.

For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.

system resume, on exiting SC7.

Ajay Gupta bc0190416e Tegra194: program stream ids for XUSB
T194 XUSB has support for XUSB virtualization. It will have one
physical function (PF) and four Virtual function (VF)

There were below two SIDs for XUSB until T186.
1) #define TEGRA_SID_XUSB_HOST    0x1bU
2) #define TEGRA_SID_XUSB_DEV    0x1cU

We have below four new SIDs added for VF(s)
3) #define TEGRA_SID_XUSB_VF0    0x5dU
4) #define TEGRA_SID_XUSB_VF1    0x5eU
5) #define TEGRA_SID_XUSB_VF2    0x5fU
6) #define TEGRA_SID_XUSB_VF3    0x60U

When virtualization is enabled then we have to disable SID override
and program above SIDs in below newly added SID registers in XUSB
PADCTL MMIO space. These registers are TZ protected and so need to
be done in ATF.
a) #define XUSB_PADCTL_HOST_AXI_STREAMID_PF_0 (0x136cU)
b) #define XUSB_PADCTL_DEV_AXI_STREAMID_PF_0  (0x139cU)
c) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_0 (0x1370U)
d) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_1 (0x1374U)
e) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_2 (0x1378U)
f) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_3 (0x137cU)

This change disables SID override and programs XUSB SIDs in
above registers to support both virtualization and non-virtualization.

Julius Werner d5dfdeb65f Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__
NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

Ambroise Vincent 6e756f6d6d Makefile: remove extra include paths in INCLUDES
Now it is needed to use the full path of the common header files.

Commit 09d40e0e08 ("Sanitise includes across codebase") provides more
information.

Varun Wadekar 8d56e24bb3 Tegra: dummy support for the io_storage backend
This patch provides dummy macros and platform files to compile
the io_storage driver backend. This patch is necessary to
remove the "--unresolved=el3_panic" linker flag from Tegra's
makefiles and allow us to revert this workaround, previously
suggested by the ARM toolchain team.

The "--unresolved=el3_panic" flag actually was a big hammer that
allowed Tegra platforms to work with armlink previously but it
masks legit errors with the code as well.

Varun Wadekar 9c2eda0193 Tegra: remove circular dependency with common_def.h
This patch stops including common_def.h from platform_def.h to
fix a circular depoendency between them.

This means platform_def.h now has to define the linker macros:
* PLATFORM_LINKER_FORMAT
* PLATFORM_LINKER_ARCH
