This board is based on Intel Tangier SoC (Intel Merrifield platform)
and may utilize ACPI powerfulness.Bring minimum support by appending initial DSDT table for it.
Note, the addresses for generated tables are carefully chosen to avoid
any conflicts with existing shadowed BIOS data. The user have somewhat
like ~31 kB available for compiled ACPI tables that ought to be enough.Reviewed-by: Bin Meng

But sometimes user is particularly interested in looking for only

This board builds an U-Boot binary that is bootable with QEMU's 'virt'
machine on ARM. The minimal QEMU command line is:qemu-system-arm -machine virt,highmem=off -bios u-boot.bin
(Note that the 'highmem=off' parameter to the 'virt' machine is required for
PCI to work in U-Boot.) This command line enables the following:
- u-boot.bin loaded and executing in the emulated flash at address 0x0
- A generated device tree blob placed at the start of RAM
- A freely configurable amount of RAM, described by the DTB
- A PL011 serial port, discoverable via the DTB
- An ARMv7 architected timer
- PSCI for rebooting the system
- A generic ECAM-based PCI host controller, discoverable via the DTBAdditionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus.
The following ones are supported by both U-Boot and Linux:- To add a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0
- To add an Intel E1000 network adapter, pass e.g.:
-net nic,model=e1000 -net user
- To add an EHCI-compliant USB host controller, pass e.g.:
-device usb-ehci,id=ehci
- To add a NVMe disk, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device nvme,drive=mydisk,serial=fooSigned-off-by: Tuomas Tynkkynen

This sort of pattern for implementing memory-mapped PCI config space
accesses appears in U-Boot twice already, and a third user is coming up.
So add helper functions to avoid code duplication, similar to how Linux
has pci_generic_config_write and pci_generic_config_read.Signed-off-by: Tuomas Tynkkynen

Many drivers had started to use dev_err, dev_info, etc. for log
functions. Currently, we are relying on , but I
guess the best home is , taking into account that
Linux defines them in .For now, I am leaving the ones in because lots of
Linux-originated code uses dev_*(), but the first argument is not
struct udevice, so we need to ignore the bogus argument. More
efforts are needed to iron out the issues.Signed-off-by: Masahiro Yamada

Collect runtime BUG/WARN into a self-contained header
to make these macros easier to use.Signed-off-by: Masahiro Yamada
-
As commit 84b8bf6d5d2a ("bug.h: move BUILD_BUG_* defines to
include/linux/bug.h") noted, include/linux/bug.h was locally
modified for U-Boot because the name conflict of error() caused
build errors at that time.Now error() is gone, so we can fully sync BUILD_BUG* with Linux.
These macros are just compile-time utilities. Nothing depends on
platform code, so it should make sense to simply copy Linux's ones.Please note Linux split BUILD_BUG stuff out into
by commit bc6245e5efd7. Let's follow it.Signed-off-by: Masahiro Yamada

When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*(). U-Boot does not support them in a clean
way. So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround. Hence this
patch, to find the best home for all printk variants. If you want to
use printk() and friends, please include . This header
is self-contained, and pulls in only a few headers.When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards. This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel". (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.The difference is the loglevel is build-time determined. To save the
image size, lower priority pr_*() are compiled out. I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

The current code, if there's both an eMMC and an MMC slot available on the
board, will swap the MMC indices based on whether we booted from the eMMC
or the MMC. This way, the MMC we're supposed to boot on will always have
the index 0.However, this causes various issues, for example when using other
components that base their behaviour on the MMC index, such as fastboot.Let's remove that hack, and take the opposite approach. The MMC will always
have the same index, but the bootcmd will pick the same device than the one
we booted from. This is done through the introduction of the mmc_bootdev
environment variable that will be filled by the board code based on the
boot device informations we can get from the SoC.In order to not introduce regressions, we also need to adjust the fastboot
MMC device and the environment device in order to set it to the eMMC, over
the MMC, like it used to be the case.Tested-by: Chen-Yu Tsai

Most architectures currently supported by U-Boot use trivial
implementations of map_to_physmem & virt_to_phys which simply cast a
physical address to a pointer for use a virtual address & vice-versa.
This results in a lot of duplicate implementations of these mapping
functions.The set of functions provided by different architectures also differs,
with some having implementations of phys_to_virt & others not. A later
patch will make use of phys_to_virt in architecture-neutral code, and so
requires that it be provided for all architectures.This patch introduces an asm-generic/io.h which provides generic
implementations of address mapping functions, allowing the duplication
of them between architectures to be removed. Once architectures are
converted to make use of this generic header it will also ensure that
all of phys_to_virt, virt_to_phys, map_physmem & unmap_physmem are
provided. The 2 families of functions differ in that map_physmem may
create dynamic mappings whilst phys_to_virt may not & therefore is more
limited in scope but doesn't require information such as a length &
flags.This patch doesn't convert any architectures to make use of this generic
header - later patches in the series will do so.Signed-off-by: Paul Burton

USB endpoint reports the period between consecutive requests to send
or receive data as bInverval in its endpoint descriptor. So far this
is ignored by xHCI driver and the 'Interval' field in xHC's endpoint
context is always programmed to zero which means 1ms for low speed
or full speed , or 125us for high speed or super speed. We should
