eb5d31645e arm: mvebu: a38x: serdes: Remove duplicate macro SOC_CTRL_REG
SoC Control 1 Register (offset 0x18204) is already defined by macro
SOC_CONTROL_REG1.

Use macro SOC_CONTROL_REG1 instead of macro SOC_CTRL_REG in ctrl_pex.c
code and remove the other definition.

646a152247 arm: a37xx: pci: Increase PCIe IO size from 64 KiB to 1 MiB
Commit 079b35a261 ("arm: a37xx: pci: Increase PCIe MEM size from 16 MiB
to 127 MiB") increased size of PCIe MEM to 127 MiB, which is the maximal
possible size for allocated 128 MiB PCIe window. PCIe IO size in that
commit was unchanged.

Armada 3720 PCIe controller supports 32-bit IO space mapping so it is
possible to assign more than 64 KiB if address space for IO.

Currently controller has assigned 127 MiB + 64 KiB memory and therefore
there is 960 KiB of unused memory. So assign it to IO space by increasing
IO window from 64 KiB to 1 MiB.

Add the System Reset Extension and the Hart State Management Extension
definitions.

Add missing RFENCE Extension enum values.

The SBI 0.1 extension constants are needed for the sbi command. Remove
an #ifdef.

dd573b6b21 riscv: image: Use the first DRAM bank for bootm_low
bootm_low is used as a base address is used to allocate space for the
FDT blob, initrd, cmdline, etc. when booting Linux. Set the default
value for RISC-V to the start of the first DRAM bank, so platforms can
get their DRAM layout from the device tree, and do not need to define
CONFIG_SYS_SDRAM_BASE.

0d625f400b riscv: Fix setting no-map in reserved memory nodes
The no-map property is wrongly skipped if a no-map reserved memory
node follows one without that property. Fix this by not remembering
the absence of a no-map property across loop iterations.

41f7be7334 serial: Add a debug console using the RISC-V SBI interface
The RISC-V SBI interface v0.1 provides a function for printing a
character to the console. Even though SBI v0.1 functions are deprecated,
the SBI console is quite useful for early debugging, because it works
without any dcache, memory, or MMIO access in S mode.

425c08faa8 clk: k210: Try harder to get the best config
In some cases, the best config cannot be used because the VCO would be
out-of-spec. In these cases, we may need to try a worse combination of r/od
in order to find the best representable config. This also adds a few test
cases to catch this and other (possible) unlikely errors.

4970874970 k210: clk: Refactor out_of_spec tests
Everything here sits in a while (true) loop. However, this introduces a
couple of layers of indentation. We can simplify the code by introducing a
single goto instead of using continue/break. This will also make adding
loops in the next patch easier.

54d5d2d56b clk: k210: Fix checking if ulongs are less than 0
The PLL functions take ulong arguments for rate, but still check if that
rate is negative (which is never true). The correct way to handle this is
to use IS_ERR_VALUE (like is already done in k210_clk_set_rate). While
we're at it, we can move the error checking up into the caller of the pll
set/get rate functions.  This also protects our other calculations from
using bogus values for rate.
