7b4ea2d888 phy: Fix u-boot coruption when fixed-phy is used
When fixed-link phy is used subnode offset is used as phy address. This
number is bigger then space allocated for bus structure (allocated via
mdio_alloc).
bus->phymap[] array has PHY_MAX_ADDR size (32).
That's why writing bus->phymap[addr] where addr is < 0 or > PHY_MAX_ADDR
is causing write to memory which can caused full U-Boot crash.

The patch is checking if address is in correct range.

adc702e229 arm: K3: Fix usage of CONFIG_SYS_K3_KEY
For signing the tiboot3.bin image, an optional KEY file can be passed
using CONFIG_SYS_K3_KEY. Right now, Makefile scripts directly takes
the config value and uses it for signing. This is okay if the build
directory is a sub-directory of source tree, otherwise it fails.
Fix it by using the path relative to the source tree.

8efae021db api: storage: Fix enumeration of storage devices
dev_stor_get() is not able to find the next available device in the current
storage group when the previous enumerated device belongs to a different
group or class (e.g. network).

The root cause is the device group iterator not being reset after an
unsuccessful search for the last returned device so that the following
search for the next available device will start from beginning.

The issue has been identified by loading and booting GRUB in a QEMU
vexpress-a9 environment.

a7f4b4b344 dm: pinctrl: Prevent (re-)configuring pins when already done before relocation
This commit prevents from re-configuring pins if those were configured
before relocation.

Some pins - like UART or DDR must be setup before relocation
(as they have 'u-boot,dm-pre-reloc' property set in DTS). Without this
change, those pins are re-configured after relocation (pre_reloc_only = 0,
so we do not "continue").
Such behavior may be a problem for DDR PAD configuration, as they might
be already leveled/tuned with original setup).

a1702746df ARM: mach-omap2: omap3: Fix GPIO clocking in SPL
OMAP3_GPIO_x is needed to enable each GPIO bank on the OMAP3
boards. At one point, the #ifdef's were replaced with
if CONFIG_IS_ENABLED but this won't work for people who need
OMAP3_GPIO_x in SPL since the SPL prefix for this option isn't
used in Kconfig.  This patch moves the check to #if defined and
also makes Kconfig select the banks if CMD_GPIO is used which
makes the checks in the code less cumbersome.

Fixes: bd8a9c14c9 ("arm: mach-omap2/omap3/clock.c: Enable
all GPIO with CMD_GPIO")

5c38e05ed8 efi_loader: Make RTS relocation more robust
While changing the RTS alignment to 64KB in commit 7a82c3051c
("efi_loader: Align runtime section to 64kb") the relocation code
started to break.

The reason for that is that we didn't actually look at the real
relocation data. We merely took the RUNTIME_CODE section as a
hint and started to relocate based on self calculated data from
that point on. That calculation was now out of sync though.

To ensure we're not running into such a situation again, this patch
makes the runtime relocation code a bit more robust. We can just
trust the phys/virt hints from the payload. We also should check that
we really only have a single section, as the code doesn't handle
multiple code relocations yet.

a0abb52c5a MIPS: remove local_irq_[save|restore] from CP0 macros
With moving write_on_tlb() to arch/mips/include/asm/mipsregs.h
there are now compiler warnings when some generic code includes
asm/io.h. This happens for example when enabling OF live tree.

02aea4da1d gpio: mscc-bitbang-spi: Add a simple gpio driver for bitbgang spi
The VCore III SoCs such as the Luton but also the Ocelot can remap an SPI
flash directly in memory. However, for writing in the flash the
communication has to be done by software.

Each of the signal used for the SPI are exposed in a single register. In
order to be able to use the soft-spi driver, the management of this pin
is done through this simple gpio driver.

Even if the main purpose of this driver is to be used by soft-spi, it can
still be used as a normal gpio driver but with limitation: for example
the first pin can't be used as output.

53bdae2418 pinctrl: mscc: Add gpio and pinctrl driver for MSCC MIPS SoCs (VcoreIII based)
This driver supports the pin and gpio controller found in the Ocelot and
Luton SoCs.

The driver was inspired from the pinctrl driver in Linux, but was
simplified and was modified to allow supporting an other SoCs (Luton).

For Ocelot and Luton the controller is the same, only the pins to program
differ.

bea91b0c9b DW SPI: Allow to overload the management of the external CS
On some platforms, as the Ocelot ones, when wanting to control the CS
through software, it is not possible to do it through the GPIO
controller. Indeed, this signal is managed through a dedicated range of
registers inside the SoC..

By declaring the external_cs_manage function as weak, it is possible to
manage the CS at platform level and then using the appropriate registers.

9766a9c653 mips: mt76xx: linkit/gardena: Don't use CONFIG_OF_EMBED
Building with CONFIG_OF_EMBED generates build warnings, as it should
only be used for debugging purposes. So let's move all MT7688 targets to
CONFIG_OF_SEPARATE instead with this patch.

a5f50e0114 mips: mt76xx: Flush d-cache in arch_misc_init() to solve d-cache issues
It has been noticed, that sometimes the d-cache is not in a
"clean-state" when U-Boot is running on MT7688. This was detected when
using the ethernet driver (which uses d-cache) and a TFTP command does
not complete. Flushing the complete d-cache (again?) here seems to fix
this issue.

This fixes following DTC warning:

arch/mips/dts/nexys4ddr.dtb: Warning (compatible_is_string_list): /ethernet@10e00000/mdio/phy@1:compatible: property is not a string list

As upstream DTS in Linux doesn't have the offending property,
simply remove it to fix the warning.
