06bda1259f ram: Introduce K3 AM654 DDR Sub System driver
K3 based AM654 devices has DDR memory subsystem that comprises
Synopys DDR controller, Synopsis DDR phy and wrapper logic to
intergrate these blocks into the device. This DDR subsystem
provides an interface to external SDRAM devices. Adding support
for the initialization of the external SDRAM devices by
configuring the DDRSS registers and using the buitin PHY
routines.

fba725f410 net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driver
This patch adds support for enabling or disabling the lane swapping
(called "port mirroring" in PHY's CFG4 register) feature of the DP83867
TI's PHY device.

One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).

Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping
support in the DP83867 TI's PHY driver") of mainline linux kernel.

510e379c49 riscv: Add QEMU virt board support
This adds QEMU RISC-V 'virt' board target support, with the hope of
helping people easily test U-Boot on RISC-V.

The QEMU virt machine models a generic RISC-V virtual machine with
support for the VirtIO standard networking and block storage devices.
It has CLINT, PLIC, 16550A UART devices in addition to VirtIO and
it also uses device-tree to pass configuration information to guest
software. It implements RISC-V privileged architecture spec v1.10.

Both 32-bit and 64-bit builds are supported. Support is pretty much
preliminary, only booting to U-Boot shell with the UART driver on
a single core. Booting Linux is not supported yet.

32cd25128b firmware: Add basic support for TI System Control Interface (TI SCI) protocol
Texas Instrument's System Control Interface (TI SCI) message protocol is
used in Texas Instrument's System on Chip (SoC) such as those in the K3
family AM654 SoC to communicate between various compute processors with
a central system controller entity.

The TI SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.

This is mostly derived from the TI SCI driver in Linux located at
drivers/firmware/ti_sci.c.

de39dc7162 arm: armv7-a: Compile and tune for armv7-a instead of armv5
arch/arm/Makefile references armv5 for backwards compatibility with
older compilers.  This patch removes those references to armv5,
since by now newer compilers are required which should have armv7
support enabled.

The Makefile also also has a list of options for mtune, but the
entry for CONFIG_CPU_V7A is empty, so this patch tunes the
CPU_V7A architecture to generic-armv7-a.

ceeee8f7b5 x86: coreboot: Add generic coreboot payload support
Currently building U-Boot as the coreboot payload requires user
to change the build configuration for a specific board during
menuconfig process. This uses the board's native device tree
to configure the hardware. For example, the device tree provides
PCI address range for the PCI host controller and U-Boot will
re-program all PCI devices' BAR to be within this range. In order
to make sure we don't mess up the hardware, we should guarantee
the range matches what coreboot programs the chipset.

But we really should make the coreboot payload support easier.
Just like EFI payload, we can create a generic coreboot payload
for all x86 boards as well. The payload is configured to include
as many generic drivers as possible. All stuff that touches low
level initialization are not allowed as such is the coreboot's
responsibility. Platform specific drivers (like gpio, spi, etc)
are not included.

separate documents"), the original README.efi was renamed to
README.u-boot_on_efi, but x86 doc still refers to the old one.

This updates the x86 doc to reference both README.u-boot_on_efi and
README.uefi.

51050ff0a2 x86: irq: Support discrete PIRQ routing registers via device tree
Currently both pirq_reg_to_linkno() and pirq_linkno_to_reg() assume
consecutive PIRQ routing control registers. But this is not always
the case on some platforms. Introduce a new device tree property
intel,pirq-regmap to describe how the PIRQ routing register offset
is mapped to the link number and adjust the irq router driver to
utilize the mapping.

fb05f0b02b x86: cougarcanyon2: Remove CONFIG_HAVE_INTEL_ME
As README.x86 already mentions, there are two SPI flashes mounted
on Intel Cougar Canyon 2 board, called SPI-0 and SPI-1 respectively.
SPI-0 stores the flash descriptor and the ME firmware. SPI-1 stores
the actual BIOS image which is U-Boot. Building a single image with
both ME firmware and U-Boot does not make sense.

This also describes the exact flash location where the u-boot.rom
should be programmed in the documentation.

6b03cd107e efi_loader: DocBook comments for boot services
With 'make htmldocs' we can generate a documentation if the function
comments follow the DocBook conventions.

This patch adjusts the comments for EFI boot services and provides the
DocBook template for the EFI subsystem.
