First set of u-boot-atmel features for the 2021.10 cycle:

This feature set converts the boards pm9261 and pm9263 Ethernet support
to DM; enables hash command for all SAM boards; fixes the NAND pmecc
bit-flips correction; adds Falcon boot for sama5d3_xplained board; and
other minor adjustments.

55661ee0e3 Revert "sama5d3: Fix Galois Field Table offsets"
This reverts commit 786f888b74.

Looks like the datasheet at
https://ww1.microchip.com/downloads/en/DeviceDoc/SAMA5D3-Series-Data-sheet-DS60001609b.pdf
is wrong, and the testing was poorly done, because the PMECC did not raise
any error, but also didn't correct any bitflips. Restoring the offsets
as they were before, makes the PMECC on sama5d3x capable of correcting
bitflips.

236f2ec432 treewide: Convert macro and uses of __section(foo) to __section("foo")
This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

First set of u-boot-atmel features for 2021.07 cycle:
This small feature set includes the implementation of the slew rate for
the PIO4 pin controller device, and a fix for arm926ejs-based
microprocessors that avoids a crash.

bbfb81c187 ARM: mach-at91: arm926ejs: fix data abort in startup returning from lowlevel_init
The startup code in arm/cpu/arm926ejs preserves the link register across
the call to lowlevel_init by using r4:

mov	r4, lr		/* perserve link reg across call */
bl	lowlevel_init	/* go setup pll,mux,memory */
mov	lr, r4		/* restore link */

The lowlevel_init function for at91 machines based on the same CPU uses r4
and hence corrupts it causing a data abort when it returns to the startup
code. This patch fixes this by using r6 instead of r4 in the lowlevel_init
function.

Discovered and the fix was tested on a AT91SAM9261 based board.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@

20e442ab2d dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

However driver names are not strictly defined, and also there are different

Merge tag 'u-boot-atmel-2020.04-a' of https://gitlab.denx.de/u-boot/custodians/u-boot-atmel

First set of u-boot-atmel features for 2020.04 cycle

This feature set is a patch series from Tudor Ambarus which includes
parsing of the spi flash SFDP parser for SST flashes, and using those
tables to retrieve unique saved per device MAC address. This is then
used as base mac address on the SAMA5D2 Wireless SOM EK board.

f10b4006a6 board: atmel: sama5d27_wlsom1_ek: Set ethaddr from spi-nor flash
The SST26VF064BEUI spi-nor flash is programmed at the factory with a
globally unique address stored in the SFDP vendor parameter table and
it is permanently writeprotected. Retrieve the EUI-48 address and set it
as ethaddr env.

bcee8d6764 dm: gpio: Allow control of GPIO uclass in SPL
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.

Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.

This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

9edefc2776 common: Move some cache and MMU functions out of common.h
These functions belong in cpu_func.h. Another option would be cache.h
but that code uses driver model and we have not moved these cache
functions to use driver model. Since they are CPU-related it seems
reasonable to put them here.

Move them over.

2189d5f1e8 Move strtomhz() to vsprintf.h
At present this function sits in its own file but it does not really
justify it. There are similar string functions in vsprintf.h, so move it
there. Also add the missing function comment.

Use the vsprintf.h include file explicitly where needed.

sama5's SFR has at offset 0x04 the DDR Configuration Register,
while sam9x60's SFR contains the EBI Chip Select Register. Add
a union to reconcile both boards.
