256df1e1c6 x86: edison: Bring minimal ACPI support to the board
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.

39665beed6 x86: tangier: Enable ACPI support for Intel Tangier
Intel Tangier SoC is a part of Intel Merrifield platform which doesn't
utilize ACPI by default. Here is an attempt to unleash ACPI flexibility
power on Intel Merrifield based platforms.

The change brings minimum support of the devices that found on
Intel Merrifield based end user device.

48ee0a87bc cmd/pxe.c: Rework initrd and bootargs handling slightly
For the initrd portion of handling our bootm arguments we do not have a
sufficiently long enough buffer for some improbable 64bit cases.  Expand
this buffer to allow for a 64bit address and almost 256MB initrd to be
used.  Make use of strncpy/strncat when constructing the values here
since we know what the worst case valid values are, length wise.

Similarly for bootargs themselves, we need to make use of strlen/sizeof
and strncpy/strncat to ensure that we don't overflow bootargs itself.

With the overlay tests now being built in sandbox Coverity has found a

7c890f149d fs-test: Add test for a filename using '..' to go back to the root
The previous commit fixed a problem in FAT code where going back to the
root directory using '..' wouldn't work correctly on FAT12 or FAT16.
Add a test to exercise this case (which was once fixed in commit
18a10d46f2 "fat: handle paths that include ../" but reintroduced due to
the directory iterator refactoring).

This test only very barely catches the problem - without the fix the
size command still gives valid output but the additional spurious
"Invalid FAT entry" error message makes it not get caught in the
'egrep -A3 ' output. I tried to make a proper test that grows the root
directory to two clusters lots of with dummy files but that causes the
write tests to crash the sandbox totally...

edce588a45 fs-test: Add FAT16 support
Currently we can only test FAT32 which is the default FAT version that
mkfs.vfat creates by default. Instead make it explicitly create either a
FAT16 or a FAT32 volume. This allows us to exercise more code, for
instance the root directory handling is done differently in FAT32 than
the older FATs.

Adding FAT12 support is a much bigger job since the test creates a 2.5GB
file and the FAT12 maximum partition size is way smaller than that.

268577669a omap: Fix warning when looking for userdata part
When eMMC was formattaed for Linux partition table, "userdata" partition
is missing. In this case, part_get_info_by_name() iterates over all
registered drivers (which are PART_TYPE_EFI, PART_TYPE_DOS and
PART_TYPE_ISO). And when it comes to PART_TYPE_ISO (which has empty
partition table), we can see next warning in U-Boot output:

    ** First descriptor is NOT a primary desc on 1:1 **

This patch switches to part_get_info_by_name_type() API in order to
check only EFI partitions for "userdata" partitions. This eliminates
mentioned warning.

32f1182926 ARM: Add a new arch + board for QEMU's 'virt' machine
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 DTB

Additionally, 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=foo

- This driver seems to be used only on MIPS so far, where the __raw and

6a3e65dea3 common: Drop LOGLEVEL to 4
While this came in with a default value of 6 I am lowering this to 4.
The MTD/UBI code has a large number of error messages that we include
now.  In addition, "normally" warning messages are not included so this
feels like a more natural level to have.

ceb9190969 dm: replace dm_dbg() with pr_debug()
As we discussed before in ML, dm_dbg() causes undefined reference
error if #define DEBUG is added to users, but not drivers/core/util.c

We do not need this macro because we can use pr_debug() instead, and
it is pretty easy to enable it for the DM core by using ccflags-y.

6990e91f09 linux/bitfield.h: import <linux/bitfield.h> from Linux 4.13
Copied from Linux 4.13.

Commit log of 3e9b3112ec74 of Linux explains well why this header
is useful.

c898cba41e dm: define dev_*() log functions in DM header
Many drivers had started to use dev_err, dev_info, etc. for log
functions.  Currently, we are relying on <linux/compat.h>, but I
guess the best home is <dm/device.h>, taking into account that
Linux defines them in <linux/device.h>.

For now, I am leaving the ones in <linux/compat.h> 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.
