c5e79ee74c ARM64: zynqmp: DT: Remove unused DDR PM domain
DDR power states are handled by the PM firmware, so this domain is
redundant. Also, since there is no device using this PM domain,
it will be powered off during boot, which is wrong.

3b6460809c tools: mkimage: Add support for initialization table for Zynq and ZynqMP
The Zynq/ZynqMP boot.bin file contains a region for register initialization
data. Filling in proper values in this table can reduce boot time
(e.g. about 50ms faster on QSPI boot) and also reduce the size of
the SPL binary.

The table is a simple text file with register+data on each line. Other
lines are simply skipped. The file can be passed to mkimage using the
"-R" parameter.

It is recommended to add reg init file to board folder.
For example:
CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int

06d43c808d arm: Set TTB XN bit in case DCACHE_OFF for LPAE mode
While we setup the mmu initially we mark set_section_dcache with
DCACHE_OFF flag. In case of non-LPAE mode the DCACHE_OFF macro
is rightly defined with TTB_SECT_XN_MASK set so as to mark all the
4GB XN. In case of LPAE mode  XN(Execute-never) bit is not set with
DCACHE_OFF. Hence XN bit is not set by default for DCACHE_OFF which
keeps all the regions execute okay and this leads to random speculative
fetches in random memory regions which was eventually caught by kernel
omap-l3-noc driver.

Fix this to mark the regions as XN by default.

better represent exactly which operation it is implementing. A dummy

b9ae6415b6 ARM: tegra: translate __asm_flush_l3_cache to assembly
When performing a cache disable function, code must not access DRAM.
That is because when the cache is disabled, it will be bypassed and all
loads and stores will be serviced by RAM. This prevents accessing any
dirty data in the cache. In turn, this means the stack cannot be
used, since that is in RAM. To guarantee that code doesn't use RAM (and
in particular the stack) __asm_flush_l3_cache() must be manually
implemented in assembly, rather than implemented in C since the compiler
won't know not to touch RAM.

Tegra186, it should be applicable to any other future SoC, and perhaps its
simple design could be back-ported to older SoCs in the future too.

68fd5c136c armv8: define get_ticks() for the ARMv8 Generic Timer
For 64-bit ARM systems we provide just a timer_read_counter()
implementation and rely on the generic non-uclass get_ticks() function
in lib/time.c to call the former.
However this function is actually not 64-bit safe, as it assumes a
"long" to be 32-bit. Beside the fact that the resulting uint64_t
isn't bigger than "long" on 64-bit architectures and thus combining two
counters makes no sense, we get all kind of weird results when we try
to OR in the high value shifted by _32_ bits.
So let's avoid that function at all and provide a straight forward
get_ticks() implementation for ARMv8, which also is in line with ARMv7.

This fixes occasional immediate time-out expiration issues I see on the
Pine64 board. The root cause of this needs to be investigated, but this
fix looks like the right thing anyway.

f28bad13b4 sunxi: Enable SMP mode for the boot CPU on sun9i (A80)
Since the A80 has many cores which we intend to use in SMP fashion,
we should set the SMP bit for the boot CPU.

ea1af9f26b sunxi: add gtbus-initialisation for sun9i
On sun9i, the GTBUS manages transaction priority and bandwidth
for multiple read ports when accessing DRAM. The initialisation
mirrors the settings from Allwinner's boot0 for now, even though
this may not be optimal for all applications (e.g. headless
systems might want to give priority to IO modules).

Adding a common callout to gtbus_init() from the SPL clock init
with a weakly defined implementation in sunxi/clock.c to fallback
to for platforms that don't require this.

297bb9e0fc sunxi: DRAM initialisation for sun9i
This adds DRAM initialisation code for sun9i, which calculates the
appropriate timings based on timing information for the supplied
DDR3 bin and the clock speeds used.

With this DRAM setup, we have verified DDR3 clocks of up to 792MHz
(i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.
