cade865a43 arm: add initial support for Amlogic P212 based on Meson GXL family
This adds platform code for the Amlogic P212 reference board based on a
Meson GXL (S905X) SoC with the Meson GXL configuration.

This initial submission only supports UART and MMC/SDCard, support for the
internal Ethernet PHY in Work In Progress.

e42f096f78 meson-gx: reserved memory regions
The Odroid C2 has two GiB of memory with two reserved regions.
reg = <0x0 0x0 0x0 0x1000000>;
reg = <0x0 0x10000000 0x0 0x200000>;

Patch
bfcef28ae4 (arm: add initial support for Amlogic Meson and
ODROID-C2) provided function dram_init_banksize to reserve the
first 16 MiB of RAM for firmware in function dram_init_banksize
in arch/arm/mach-meson/board.c and defined
CONFIG_NR_DRAM_BANKS = 1.

With this patch dram_init_banksize is changed to additionally
reserve the 2MiB region for the ARM Trusted Firmware (BL31).
CONFIG_NR_DRAM_BANKS is set to 2.

76b00aca4f board_f: Drop setup_dram_config() wrapper
By making dram_init_banksize() return an error code we can drop the
wrapper. Adjust this and clean up all implementations.

51bfb5b6f5 arm: Disable HVC PSCI calls by default
All systems that are running on armv8 are running bare metal with firmware
that implements PSCI running in EL3. That means we don't really need to expose
the hypercall variants of them.

This patch leaves the code in, but makes the code explicit enough to have the
compiler optimize it out. With this we don't need to worry about hvc vs smc
calling convention when calling psci helper functions.

cd4b0c5fea armv8: mmu: Add support of non-identical mapping
Introduce virtual and physical addresses in the mapping table. This change
have no impact on existing boards because they all use idential mapping.

bfcef28ae4 arm: add initial support for Amlogic Meson and ODROID-C2
This adds platform code for the Amlogic Meson GXBaby (S905) SoC and a
board definition for ODROID-C2. This initial submission only supports
UART and Ethernet (through the existing Designware driver). DTS files
are the ones submitted to Linux arm-soc for 4.7 [1].
