da91cfed54 ARM: non-sec: flush code cacheline aligned
Flush operations need to be cacheline aligned to take effect, make
sure to flush always complete cachelines. This avoids messages such
as:
CACHE: Misaligned operation at range [00900000, 009004d9]

0e1709476b armv8: mmu: Detect page table overflow in emergency pt creation
We create 2 sets of page tables: One for normal operation, one for
emergency (used while modifying the former).

Because the page tables grow dynamically, we have code that checks
for overflow. Unfortunately we didn't adjust the available space
variable while creating the emergency tables, so potentially someone
might run into an overflow there (not seen in real world yet though!).

Fix it by properly adjusting the size as well as the base offset in
emergency page table creation.

bb6b142fc1 treewide: move CONFIG_PHYS_64BIT to Kconfig
We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so
that it is always available to the build system.  Otherwise we can run
into cases where we have inconsistent sizes of certain attributes.

Ravi Babu reported offset mismatch of struct dwc3 across files since
commit 95ebc253e6 ("types.h: move and redefine resource_size_t").
Since the commit, resource_addr_t points to phys_addr_t, whose size
is dependent on CONFIG_PHYS_64BIT for ARM architecture.

I tried my best to use "select" where possible (for example, ARMv8
architecture) because I think this kind of option is generally user-
unconfigurable.  However, I see some of PowerPC boards have 36BIT
defconfigs as well as 32BIT ones.  I moved CONFIG_PHYS_64BIT to the
defconfigs for such boards.

CONFIG_36BIT is no longer referenced, so all of the defines were
removed from CONFIG_SYS_EXTRA_OPTIONS.

Fixes: 95ebc253e6 ("types.h: move and redefine resource_size_t")

a78cd86132 ARM: Rework and correct barrier definitions
As part of testing booting Linux kernels on Rockchip devices, it was
discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for
some cases incomplete isb definitions.  This was causing a failure to
boot of the Linux kernel.

In order to solve this problem as well as cover any corner cases that we
may also have had a number of changes are made in order to consolidate
things.  First, <asm/barriers.h> now becomes the source of isb/dsb/dmb
definitions.  This however introduces another complexity.  Due to
needing to build SPL for 32bit tegra with -march=armv4 we need to borrow
the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete
form.  Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add
a comment about it.  Now that we can always know what the target CPU is
capable off we can get always do the correct thing for the barrier.  The
final part of this is that need to be consistent everywhere and call
isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the
function names in others.

Colibri iMX7S/iMX7D. The two modules/SoC's are very similar hence

335b4e53c9 ARM: am33xx: Always inhibit init/refresh during DDR phy init
A couple of commits have modified the am33xx/am437x ddr2/ddr3
initialization path to fix certain issues, but have had the side effect
of causing L3 noc errors during initialization. The two commits are:

69b918 "am33xx,ddr3: fix ddr3 sdram configuration"
fc46ba "arm: am437x: Enable hardware leveling for EMIF"

The EMIF_REG_INITREF_DIS_MASK bit still needs to be set for all
platforms. This delays initialization and refresh until a later stage.
The 500us timer can be programmed for platforms that require it
and for platforms that don't require it. It is currently hardcoded
for 400MHz systems. For systems with a higher memory frequency
this needs to be a larger value, and for systems with a lower
memory frequency this can be a lower value. This can be
considered a separate issue and corrected in a later commit.

980d6a5511 ARM: Add an empty secure stack section
Until now we've been using memory beyond psci_text_end as stack space
for the secure monitor or PSCI implementation, even if space was not
allocated for it.

This was partially fixed in ("ARM: allocate extra space for PSCI stack
in secure section during link phase"). However, calculating stack space
from psci_text_end in one place, while allocating the space in another
is error prone.

This patch adds a separate empty secure stack section, with space for
CONFIG_ARMV7_PSCI_NR_CPUS stacks, each 1 KB. There's also
__secure_stack_start and __secure_stack_end symbols. The linker script
handles calculating the correct VMAs for the stack section. For
platforms that relocate/copy the secure monitor before using it, the
space is not allocated in the executable, saving space.

For platforms that do not define CONFIG_ARMV7_PSCI_NR_CPUS, a whole page
of stack space for 4 CPUs is allocated, matching the previous behavior.

a1274cc94a ARM: Page align secure section only when it is executed in situ
Targets that define CONFIG_ARMV7_SECURE_BASE will copy the secure section
to another address before execution.

Since the secure section in the u-boot image is only storage, there's
no reason to page align it and increase the binary image size.

Page align the secure section only when CONFIG_ARMV7_SECURE_BASE is not
defined. And instead of just aligning the __secure_start symbol, align
the whole .__secure_start section. This also makes the section empty,
so we need to add KEEP() to the input entry to prevent the section from
being garbage collected.

Also use ld constant "COMMONPAGESIZE" instead of hardcoded page size.

6b6024eadb arm64: add better and more generic spin-table support
There are two enable methods supported by ARM64 Linux; psci and
spin-table.  The latter is simpler and helpful for quick SoC bring
up.  My main motivation for this patch is to improve the spin-table
support, which allows us to boot an ARMv8 system without the ARM
Trusted Firmware.

Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S
and the spin-table is supported in a really ad-hoc way, and I see
some problems:

  - We must hard-code CPU_RELEASE_ADDR so that it matches the
    "cpu-release-addr" property in the DT that comes from the
    kernel tree.

  - The Documentation/arm64/booting.txt in Linux requires that
    the release address must be zero-initialized, but it is not
    cared by the common code in U-Boot.  We must do it in a board
    function.

  - There is no systematic way to protect the spin-table code from
    the kernel.  We are supposed to do it in a board specific manner,
    but it is difficult to predict where the spin-table code will be
    located after the relocation.  So, it also makes difficult to
    hard-code /memreserve/ in the DT of the kernel.

So, here is a patch to solve those problems; the DT is run-time
modified to reserve the spin-table code (+ cpu-release-addr).
Also, the "cpu-release-addr" property is set to an appropriate
address after the relocation, which means we no longer need the
hard-coded CPU_RELEASE_ADDR.

b56e06d343 ARM: allocate extra space for PSCI stack in secure section during link phase
The PSCI implementation expects at most 2 pages worth of space reserved
at the end of the secure section for its stacks. If PSCI is relocated to
secure SRAM, then everything is fine. If no secure SRAM is available,
and PSCI remains in main memory, the reserved memory space doesn't cover
the space used by the stack.

If one accesses PSCI after Linux has fully booted, the memory that should
have been reserved for the PSCI stacks may have been used by the kernel
or userspace, and would be corrupted. Observed after effects include the
system hanging or telinit core dumping when trying to reboot. It seems
the init process gets hit the most on my test bed.

This fix allocates the space used by the PSCI stacks in the secure
section by skipping pages in the linker script, but only when there is
no secure SRAM, to avoid bloating the binary.

This fix is only a stop gap. It would be better to rework the stack
allocation mechanism, maybe with proper usage of CONFIG_ macros and an
explicit symbol.

b5bd09820c arm: Allow skipping of low-level init with I-cache on
At present CONFIG_SKIP_LOWLEVEL_INIT prevents U-Boot from calling
lowlevel_init(). This means that the instruction cache is not enabled and
the board runs very slowly.

What is really needed in many cases is to skip the call to lowlevel_init()
but still perform CP15 init. Add an option to handle this.

1428d83270 arm: dra7xx: Assign omap_vcores based on board type
Currently omap_vcores which holds pmic data is being assigned based
on the SoC type. PMIC is not a part of SoC. It is logical to
to assign omap_vcores based on board type. Hence over ride the
vcores_init function and assign omap_vcores based on the board type.
