f2ef204312 arm: v7R: Add support for MPU
The Memory Protection Unit(MPU) allows to partition memory into regions
and set individual protection attributes for each region. In absence
of MPU a default map[1] will take effect. Add support for configuring
MPU on Cortex-R, by reusing the existing support for Cortex-M processor.

4bbd6b1d94 arm: v7R: Add initial support
The Cortex-R* processors are a mid-range CPUs for use in deeply-embedded,
real-time systems. It implements the ARMv7-R architecture, and includes
Thumb-2 technology for optimum code density and processing throughput.

Except for MPU(Memory Protection Unit) and few CP15 registers, most of the
features are compatible with v7 architecture. So,reuse the same armv7
folder and introduce a new config CPU_V7R in order to differentiate
from v7 based platforms.

acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

1a047c23f9 arm: psci: save context id for cpu_on PSCI command
Save and use the 3rd parameter of PSCI CPU_ON request: context_id.

The context_id parameter is only meaningful to the caller.
U-Boot PSCI preserves a copy of the value passed in this parameter.
Following wakeup from a  powerdown state, U-BOOT PSCI places
this value in R0 when it first enters the OS.

NB: this context id is not (yet?) used by Linux but it is mandatory
    to be PSCI compliant.

update armv7 psci functions:
- psci_save_target_pc(): keep for backward compatibility with
  current platform (only save PC and force context id to 0)
  => should be removed when all platform migrate to the new API

- psci_save(): new API to use by ARMv7 platform with PSCI,
  save pc (= entry_point_address) and context_id

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
In order that we can use eth_env_* even when CONFIG_NET isn't set, move

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

variable")

when Ethernet is required in Linux, but not U-Boot.

f5bd13ed57 mach-stm32: Use default memory map as background region
On linux kernel side, on STM32F7 and STM32H7 SoCs, DMA requires
uncachable regions. These regions are defined in DT.
Since kernel linux v4.15, on ARMv7-M Cortex, kernel is able
to configure MPU regions depending on DT settings.

As kernel is able to configure MPU, this allows to remove
MPU region settings in bootloader.

On Cortex M processors, MPU allows to use a default memory map.
(see B3.5.4 MPU Control Register, MPU_CTRL in
https://developer.arm.com/products/architecture/m-profile/docs/ddi0403/latest/armv7-m-architecture-reference-manual)

family with an additional MPU region corresponding to the SDRAM area.

- Port inhibit_portals() from PowerPC to ARM. This function is used in

d852600ef0 arm: Exercise v7_arch_cp15_set_acr even without errata fixups
By applying this patch, we are ensuring that the code paths
responsible for applying errata workarounds are also exercised
on CPU revisions, which actually don't need these workarounds.

Only CONFIG_ARM_ERRATA_621766, CONFIG_ARM_ERRATA_454179,
CONFIG_ARM_ERRATA_725233 and CONFIG_ARM_ERRATA_430973 are
covered by this patch (Cortex-A8).

This improves code coverage when testing U-Boot builds
on newer hardware. In particular, the problematic commit
00bbe96eba ("arm: omap: Unify get_device_type() function")
would break both BeageBoard and BeagleBoard XM rather than
just older BeagleBoard.

As an additional bonus, we need fewer instructins and the SPL

78ad457b2d armv8: shrink exception table code
In the moment our exception entry code needs 34 instructions, so we
can't use put it directly into the table entry, which offers "only"
32 instructions there. Right now we just put an unconditional branch
there, then use a macro to place the 34 instructions *per entry* after
that. That effectivly doubles the size of our exception table, which
is quite a waste, given that we use it mostly for debugging purposes.

Since the register saving part is actually identical, let's just convert
that macro into a function, and "bl" into it directly from the exception
slot, of course after having saved at least the original LR.
This saves us about 950 bytes of code, which is quite a relief for some
tight SPLs, in particular the 64-bit Allwinner ones.

710d0cd79e armv8: fsl-layerscape: Allocate Secure memory from first ddr region
This change is required due to trusted OS (OP-TEE) not being position
independent code, it requires compile time fixed base address.

To take care of this it is assumed that all layerscape armv8 platforms
has minimum 2G ddr in first region. So we can have fixed address
space (66 MB -> (2MB for PPA + 64MB for trusted OS)) allocated from
top of first 2G ddr region and compile trusted OS with this fixed
base address.

But one exception here is ls1012 where we have only 1G (rdb) or 512M
(frdm) ddr memory. For those we can have different fixed compile time
base addresses for trusted OS.

7458c5e65f armv8: Apply workaround for USB erratum A-009007 to LS1088A
Rx Compliance tests may fail intermittently at high jitter
frequencies using default register values.

Program register USB_PHY_RX_OVRD_IN_HI in certain sequence
to make the Rx compliance test pass.

723b43daec blk: Remove various places that do flush cache after read
All these places seem to inherit the codes from the MMC driver where
a FIXME was put in the comment. However the correct operation after
read should be cache invalidate, not flush.

The underlying drivers should be responsible for the cache operation.
Remove these codes completely.

CCN-504 HPF registers were believed to be accessible only from EL3.
However, recent tests proved otherwise. Remove checking for exception
level to re-enable L3 cache flushing for all levels.
