SPL_ROCKCHIP_COMMON_BOARD, an almost identical option, has a title but

Instead of hardcode the base address, we can get them from the build
output, eg. get the SYS_TEXT_BASE from .config and get optee base from
DRAM_BASE.
We can use this script for SoCs with DRAM base not from 0x60000000(rk3229
and many other 32bit Rockchip SoCs), eg. rk3288 DRAM base is 0.

05767707a8 dts: am335x-brsmarc1/xre1: insert phy_id again
commit 3b3e8a37d3
("arm: dts: am335x: sync cpsw/mdio/phy with latest linux - drop phy_id")

did sync with recent linux kernel and replaced therefore the 'phy_id'
property with a phy-handle pointing to the mdio.

This is OK for linux, but introduces trouble with the already running
vxWorks on this target.

So this commit here re-inerts the phy_id property beside the phy-handle
property to be compatible with both.

90ae281437 riscv: add option to wait for ack from secondary harts in smp functions
Add a wait option to smp_call_function() to wait for the secondary harts
to acknowledge the call-function request. The request is considered to
be acknowledged once each secondary hart has cleared the corresponding
IPI.

As part of the call-function request, the secondary harts invalidate the
instruction cache after clearing the IPI. This adds a delay between
acknowledgment (clear IPI) and fulfillment (call function) of the
request. We want to use the acknowledgment to be able to judge when the
request has been completed. Remove the delay by clearing the IPI after
cache invalidation and just before calling the function from the
request.

6b20dc165e riscv: increase stack size to avoid a stack overflow during distro boot
This fixes a problem, where booting Linux using distro boot will
sometimes lead to an invalid instruction exception on the main hart. The
secondary harts are not affected and boot Linux successfully. The root
cause of this problem is a stack overflow on the main hart.

With distro boot, the current default stack size of 8KiB on RISC-V is
not sufficient and will cause a stack overflow. The stacks are allocated
sequentially. In the case of a stack overflow the stack of the main hart
can reach into that of another hart and be corrupted.

The stack overflow previously did not cause any problems, because only
stack frames, which are not used anymore since the hart enters Linux,
were corrupted. Starting with GCC 9, the stack usage has decreased. Now,
only the most recent stack frame overflows into the stack of a secondary
hart and is corrupted. The illegal instruction exception is caused by
the secondary hart overwriting the return address in the stack frame of
the main hart with an address that does not include valid code.

Increase the default stack size of each hart to 16KiB to avoid this
problem.

1045ff4d1a ARM: DRA7: Fixup DSP OPP_HIGH clock rate on DRA76P/DRA77P SoCs
The commit 1b42ab3eda ("ARM: DRA7: Fixup DSPEVE, IVA and GPU clock
frequencies based on OPP") added the core logic to update the kernel
device-tree blob to adjust the DSP, IVA and GPU DPLL clocks based on
a one-time OPP choice selected in U-Boot for most of the DRA7xx/AM57xx
family of SoCs.

The DSPs on DRA76xP/DRA77xP SoCs (DRA76x ACD package SoCs) though
provide a higher performance and can run at a higher clock frequency
of 850 MHz at OPP_HIGH instead of 750 MHz. Fix up the logic to use the
correct clock rates on these SoCs. Note that this higher clock rate is
not applicable to other Jacinto 6 Plus SoCs (DRA75xP/DRA74xP SoCs or
AM574x SoCs) that follow the ABZ package.

0c5c3f2935 arm: -march=armv5t for ARM11
In GCC 9 support for the Armv5 and Armv5E architectures (which have no
known implementations) has been removed, cf.
https://gcc.gnu.org/gcc-9/changes.html

Commit 16540d07fd ("arm: fix -march for ARM11") changed the value of the
compiler flag from -march=armv5 and -march=armv5t into -march=armv6 for
ARM11.

The values prior to this patch were:

    arch-$(CONFIG_CPU_ARM1136)     =-march=armv5
    arch-$(CONFIG_CPU_ARM1176)     =-march=armv5t

The change lead to a regression with the Raspberry Pi Zero W not booting
anymore.

Use -march=armv5t both for ARM1136 and ARM1176.

6a4b07e086 imx8m: fix rom version check to unbreak some B0 chips
Recently the version check was improved to be able to determine that
we're running on SoC revision 2.1.  A check for B0 was tightened so
that it now must equal 0x20 instead of being bigger than 0x20.  On
some B0 chips the value returned is 0x1020 instead of 0x20.  This
means even though it's B0, the check will fail and code relying on
the correct chip revision will make wrong decisions.  There is no
documentation of those bits, but it seems that NXP always uses a
byte to encode the revision.  Thus remove the upper bits to fix the
regression.

in case the M4 core is running. Also make sure that the i.MX 7
specific rpmsg driver does not get loaded in case we do not carve

The LDOVL definitions is common to all the modes, not only RUN mode,
so in order to avoid confusion, remove the _RUN notation from the PMC1
LDOVL definitions.

b8cabb0e3d mx7ulp: Introduce the CONFIG_LDO_ENABLED_MODE option
Introduce the CONFIG_LDO_ENABLED_MODE option so that i.MX7ULP boards
designed to operate with LDO enabled mode can work with 0.95V at LDO
output in RUN mode as per the datasheet.

72a093a8ac mx7ulp: Print the LDO mode status
As per the i.MX7ULP datasheet, it can boot in LDO enabled mode
or LDO bypass mode.

Print the LDO mode status in the U-Boot log for convenience.

4ee6d51c5a pwm: rk_pwm: Make PWM driver to support all Rockchip Socs
This PWM driver can be used to support pwm functions
for on all Rockchip Socs.

The previous chips than RK3288 did not support polarity,
and register layout was different from the RK3288 PWM.

The RK3288 keep the current functions.

RK3328 and the chips after it, which can support hardware lock,
configure duty, period and polarity at next same period, to
prevent the intermediate temporary state.

fd3a7ae8e6 rockchip: misc: protect serial# from getting overwritten
serial# is one of the vendor properties and thus protected from being
overwritten if already set. If env_set is called anyway this result in
some nasty warnings, so check for presence before trying that.

In the same direction check for the presence of cpuid# and compare it
to the actual hardware and emit a warning if they don't match.

d490fadc70 rockchip: misc: don't fail if eth_addr already set
rockchip_setup_macaddr() runs from an initcall, so returning an error
code will make that initcall fail thus breaking the boot process.

And if an ethernet address is already set this is definitly not a
cause for that, so just return success in that case.

c541bfda2f rockchip: px30: Add support for using UART3 as debug UART
Some generic PX30 SoMs found in the wild use UART3 as their debug output
instead of UART2 (used for MMC) and UART5.

Make it possible to use UART3 as early debug output, with the associated
clock and pinmux configuration. Two sets of output pins are supported (M0/M1).

Future users should also note that the pinmux default in the dts is to use
the M1 pins while the Kconfig option takes M0 as a default.
