4916f4586e x86: pinctrl: Add a way to get the pinctrl reg address
At present we can query the offset of a pinctrl register within the p2sb.
For ACPI we need to get the actual address of the register. Add a function
to handle this and rename the old one to more accurately reflect its
purpose.

7f926c9648 x86: Add support for building up an NHLT structure
The Intel Non-High-Definition-Audio Link Table (NHLT) table describes the
audio codecs and connections in a system. Various devices can contribute
information to produce the table.

Add functions to allow adding to the structure that is eventually written
to the ACPI tables. Also add the device-tree bindings.

fefac0b064 dm: acpi: Enhance acpi_get_name()
For many device types it is possible to figure out the name just by
looking at its uclass or parent. Add a function to handle this, since it
allows us to cover the vast majority of cases automatically.

However it is sometimes impossible to figure out an ACPI name for a device
just by looking at its uclass. For example a touch device may have a
vendor-specific name. Add a new "acpi,name" property to allow a custom
name to be created.

With this new feature we can drop the get_name() methods in the sandbox
I2C and SPI drivers. They were only added for testing purposes. Update the
tests to use the new values.

3c41728d80 imx8m: Refactor the OPTEE memory removal
Current codes assume the OPTEE address is at the end of first DRAM bank.
Adjust the process to allow OPTEE in the middle of first bank.

When OPTEE memory is removed from first bank, it may split the first bank
to two banks, adjust the MMU table for the split case,
Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.

2f3c92060d imx8m: workaround ROM serror
ROM SError happens on two cases:

1. ERR050342, on iMX8MQ HDCP enabled parts ROM writes to GPV1 register, but
when ROM patch lock is fused, this write will cause SError.

2. ERR050350, on iMX8MQ/MM/MN, when the field return fuse is burned, HAB
is field return mode, but the last 4K of ROM is still protected and cause
SError.

Since ROM mask SError until ATF unmask it, so then ATF always meets the
exception. This patch works around the issue in SPL by enabling SPL
Exception vectors table and the SError exception, take the exception
to eret immediately to clear the SError.

f3acb02386 drivers: ddr: imx8mp: Add inline ECC feature support
the DRAM Controller in i.MX8MP will support a feature called "Inline ECC".
This is supported for all 3 supported DRAM technologies (LPDDR4, DDR4 and
DDR3L). When this feature is enabled by software, the DRAM Controller
reserves 12.5% of DRAM capacity for ECC information, and presents only
the non-ECC portion (lower 87.5% of the installed capacity of DRAM) to
the rest of the SoC.
The DRAM memory can be divided into 8 regions so that if a use case only
requires ECC protection on a subset of memory, then only that subset of
memory need support inline ECC. If this occurs, then there is no
performance penalty accessing the non-ECC-protected memory (no need to
access ECC for this portion of the memory map). This is all configured
with the DRAM Controller.

Since commit 1517126fda ("ARM: uniphier: select DM_ETH"), DM-based
drivers/net/smc911x.c is compiled, but it is never probed because the

I need a skeleton driver to populate child devices (but the next commit

56d463bdba ARM: uniphier: consolidate SoC select menu
Currently, the supports for the following two ARMv7 SoC groups
are exclusive, because the boot ROM loads the SPL to a different
address:

 - LD4, sLD8                 (SPL is loaded at 0x00040000)
 - Pro4, Pro5, PXs2, LD6b    (SPL is loaded at 0x00100000)

This limitation exists only when CONFIG_SPL=y.

Instead of using crappy CONFIG options, checking SPL and SPL_TEXT_BASE
is cleaner.

1f8e6a670c Revert "ARM: uniphier: add weird workaround code for LD20"
This reverts commit 45f41c134b.

This weird workaround was the best I came up with at that time
to boot U-Boot from TF-A.

I noticed U-Boot successfully boots on LD20 (i.e. CA72 CPU) by using
the latest TF-A.

Specifically, since the following TF-A commit, U-Boot runs at EL2
instead of EL1, and this issue went away as a side-effect.

|commit f998a052fd94ea082833109f25b94ed5bfa24e8b
|Author: Masahiro Yamada <yamada.masahiro@socionext.com>
|Date:   Thu Jul 25 10:57:38 2019 +0900
|
|    uniphier: run BL33 at EL2
|
|    All the SoCs in 64-bit UniPhier SoC family support EL2.
|
|    Just hard-code MODE_EL2 instead of using el_implemented() helper.

|    Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

However, if I reverted that, this problem would come back, presumably
because some EL1 code in U-Boot triggers this issue.

Now that commit f8ddd8cbb5 ("arm64: issue ISB after updating system
registers") fixed this issue properly, this weird workaround is no
longer needed irrespective of the exception level at which U-Boot runs.

e3e2470fdd drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers

However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This

for valid driver names.

3dada5a1a8 x86: fsp: Reinit the FPU after FSP meminit
The APL FSP appears to leave the FPU in a bad state in that it has
registers in use. This causes an error when the next FPU operation is
performed.

Work around this by re-resetting the FPU after calling FSP-M. This allows
the freetype console to work correctly.

f8ddd8cbb5 arm64: issue ISB after updating system registers
ARM Architecture reference manual clearly states that PE pipeline
should be flushed after changes to some system registers. Refer to
paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture
Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI
0487B.a).

Failing to issue instruction synchronization barrier can lead to
spurious errors, like synchronous exception when accessing FPU
registers. This is very prominent on CPUs with long instruction
pipeline, like ARM Cortex A72.

This change fixes the following U-Boot panic:

 "Synchronous Abort" handler, esr 0x1fe00000

While executing instruction

 str     q0, [sp, #112]

in vsnprintf() prologue. This panic was observed only on Cortex A72 so
far.

This patch places ISBs on other strategic places as well.

Also, this probably is the right fix for the issue workarounded in the
commit 45f41c134b ("ARM: uniphier: add weird workaround code for LD20")

SPL_ATF_NO_PLATFORM_PARAM is selected by default for RK3399 configs, to
guard against issues when used with TF-A versions that perform
insufficient validation on the platform parameter. However, since commit
8109f738ffa7 "rockchip: increase FDT buffer size" in TF-A, passing a
device tree as platform parameter no longer causes problems for upstream
TF-A for RK3399.

Since SPL_ATF_NO_PLATFORM_PARAM doesn't need to be selected when using
upstream TF-A, change the Kconfig option from select to imply. It'll
still default to being selected but can be deselected by a user if they
know they will be using a compatible version of TF-A.

VAMRC RK3399Pro SOM need to mount on top of radxa dalang
carrier board for making Rock Pi N10 SBC.

So, add initial support for Rock Pi N10 by including rk3399,
rk3399pro vamrc-som and raxda dalang carrier board dtsi files.

rk3399pro-rock-pi-n10.dts was synced from linux-next v5.7-rc1.

Tested
- ROCK PI N10 Model B
- ROCK PI N10 Model C
- Boot from SD

29dac6316a ARM: dts: rockchip: Sync v5.7-rc1 Radxa Dalang Carrier
Carrier board often referred as baseboard. For making
complete SBC or any other industrial boards, these
carrier boards will be used with associated SOMs.

Radxa has Dalang carrier board which supports on-board
peripherals, ports like USB-2.0, USB-3.0, HDMI, MIPI DSI/CSI,
eDP, Ethernet, WiFi, PCIe, USB-C, 40-Pin GPIO header and etc.

Right now Dalang carrier board is used with two SBC-variants:
Rock Pi N10 => VMARC RK3399Por SOM + Dalang carrier board
Rock Pi N8  => VMARC RK3288 SOM + Dalang carrier board(+codec)

So add this carrier board dtsi as a separate file in
ARM directory, so-that the same can reuse it in both
rk3288, rk3399pro variants of Rockchip SOMs.

Sync this dtsi from linux-next v5.7-rc1.

- Re-sync our <linux/compiler*h> files with v5.7-rc5 from upstream.
- Fully resync checkpatch.pl with v5.7 release.

To safely to all of the above, we have a few bugfixes about functions
that need a 'static inline' but weren't.  We also stop setting
CROSS_COMPILE in arch/*/config.mk.  Finally, with the above changes
boards can now opt-in to optimizing inlining and we do this for the

eb75ee4bd6 riscv: dts: hifive-unleashed-a00: add cpu aliases
Add cpu aliases to U-Boot specific dtsi for hifive-unleashed.
Without aliases we see that the CPU device sequence numbers are set
randomly and the cpu list/detail command will show it as follows:
=> cpu list
  1: cpu@1      rv64imafdc
  2: cpu@2      rv64imafdc
  3: cpu@3      rv64imafdc
  0: cpu@4      rv64imafdc

Seems like CPU probing with dm-model also relies on aliases as observed
in case spi. The fu540-c000-u-boot.dtsi has cpu nodes and so adding
corresponding aliases we can ensure that cpu devices are assigned
proper sequence as follows:

=> cpu list
  1: cpu@1      rv64imafdc
  2: cpu@2      rv64imafdc
  3: cpu@3      rv64imafdc

a7c81fc853 riscv: Add Sipeed Maix support
The Sipeed Maix series is a collection of boards built around the RISC-V
Kendryte K210 processor. This processor contains several peripherals to
accelerate neural network processing and other "ai" tasks. This includes a
"KPU" neural network processor, an audio processor supporting beamforming
reception, and a digital video port supporting capture and output at VGA
resolution. Other peripherals include 8M of sram (accessible with and
without caching); remappable pins, including 40 GPIOs; AES, FFT, and SHA256
accelerators; a DMA controller; and I2C, I2S, and SPI controllers. Maix
peripherals vary, but include spi flash; on-board usb-serial bridges; ports
for cameras, displays, and sd cards; and ESP32 chips. Currently, only the
Sipeed Maix Bit V2.0 (bitm) is supported, but the boards are fairly
similar.

Documentation for Maix boards is located at
<http://dl.sipeed.com/MAIX/HDK/>.  Documentation for the Kendryte K210 is
located at <https://kendryte.com/downloads/>. However, hardware details are
rather lacking, so most technical reference has been taken from the
standalone sdk located at
<https://github.com/kendryte/kendryte-standalone-sdk>.
