In commit a1274cc94a20 ("ARM: Page align secure section only when it is
executed in situ"), we used output section attributes (the "ALIGN"
keyword after the colon) to specify the alignment requirements. Using
the constant "COMMONPAGE" there was recently broken in binutils 2.31 [1].
Binutils maintainer Alan Modra suggested the former method would still
work. Since both methods achieve the same result, this patch does just
that. This fixes the "reboot after bootm" issue we've been seeing on
sunxi when booting non-secure.

Even though the exception vector table is a fundamental part of the ARM
architecture, U-Boot mostly does not make real use of it, except when
crash dumping. But having it in takes up quite some space, partly due to
the architectural alignment requirement of 2KB. Since we don't take special
care of that, the compiler adds a more or less random amount of padding
space, which increases the image size quite a bit, especially for the SPL.
On a typical Allwinner build this is around 1.5KB of padding, plus 1KB
for the vector table (mostly padding space again), then some extra code
to do the actual handling. This amounts to almost 10% of the maximum image
size, which is quite a lot for a pure debugging feature.
Add a Kconfig symbol to allow the exception vector table to be left out
of the build for the SPL.
For now this is "default y" for everyone, but specific defconfigs,
platforms or .config files can opt out here at will, to mitigate the code
size pressure we see for some SPLs.

The arm64 exception handling code is quite big, mostly due to
architectural alignment requirements. Each exception entry spans 32
instructions, which sounds generous, but is too small to fit all of the
save/branch/restore code in there. So at the moment we use only four
instructions, branching into shared save and restore routines.
To not leave the space for those remaining 28 instructions wasted, let's
split the save and restore routines and stuff them into the gaps.
This saves about 250 bytes of code, which is helpful for those tight
SPLs.

Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.
In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".
Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.
With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

The Allwinner A64 SoCs suffers from an arch timer implementation erratum,
where sometimes the lower 11 bits of the counter value erroneously
become all 0's or all 1's [1]. This leads to sudden jumps, both forwards and
backwards, with the latter one often showing weird behaviour.
Port the workaround proposed for Linux to U-Boot and activate it for all
A64 boards.
This fixes crashes when accessing MMC devices (SD cards), caused by a
recent change to actually use the counter value for timeout checks.

Cortex-A15 for CVE-2017-5715
As recommended by Arm in [1], ACTLR[0] (Enable invalidates of BTB)
needs to be set[2] for BTB to be invalidated on ICIALLU. This needs to
be done unconditionally for Cortex-A15 processors. Provide a config
option for platforms to enable this option based on impact analysis
for products.
NOTE: This patch in itself is NOT the final solution, this requires:
a) Implementation of v7_arch_cp15_set_acr on SoCs which may not
provide direct access to ACR register.
b) Operating Systems such as Linux to provide adequate workaround in the
right locations.
c) This workaround applies to only the boot processor. It is important
to apply workaround as necessary (context-save-restore) around low
power context loss OR additional processors as necessary in either
firmware support OR elsewhere in OS.

We currently handle the UEFI runtime reset / power off case handling via
a switch statement. Compilers (gcc in my case) may opt to handle these via
jump tables which they may conveniently put into .rodata which is not part
of the runtime section, so it will be unreachable when executed.
Fix this by just converting the switch statement into an if/else statement.
It produces smaller code that is faster and also correct because we no
longer refer .rodata from efi runtime code.

but MMU map is 2GB there could be spurious accesses which was seen in past
when mapping is not fitting with actual memory installed.

Mask HRESET_B after cleared the the RCW_SRC, because in the workaround
we override the RCW_SRC and if HRESET_B is issued after the override
then SoC cannot find valid RCW as the RCW_SRC was overwritten and
result in hang. So we need to mask HRESET_B in case user asserts it,
and the PORESET_B should be asserted which leads to resampling of
cfg_rcw_src pins and loading of correct RCW_SRC.

JR3 was getting removed from device tree only if random number
generation was successful. However, if SEC firmware is present,
JR3 should be removed from device tree node irrespective of the
random seed generation as SEC firmware reserves it for it's use.
Not removing it in case of random number generation failure causes
the kernel to crash.
Random number generation was being called twice. This is not
required. If SEC firmware is running, SIP call can be made to the SEC
firmware to get the random number. This call itself would return
failure if function is not supported. Duplicate calling of random
number generation function has been removed.
