40fef04906 Introduce arch_phys_memset which works like memset but on physical memory
The default implementation of this function is just memset, but other
implementations will be needed when physical memory isn't accessible by
U-Boot using normal addressing mechanisms.

b16f521a5e x86: Allow excluding reset vector code from u-boot
When running from coreboot we don't want this code.

This version works by ifdef-ing out all of the code that would go
into those sections and all the code that refers to it. The sections are
then empty, and the linker will either leave them empty for the loader
to ignore or remove them entirely.

d95f6ec733 fdt: Add option to default to most compatible conf in a fit image
When booting a fit image with multiple configurations, the user either has to
specify which configuration to use explicitly, or there has to be a default
defined which is chosen automatically. This change adds an option to change
that behavior so that a configuration can be selected explicitly, or the
configuration which has the device tree that claims to be compatible with the
earliest item in U-Boot's device tree.

In other words, if U-Boot claimed to be compatible with A, B, and then C, and
the configurations claimed to be compatible with A, D and B, D and D, E, the
first configuration, A, D, would be chosen. Both the first and second
configurations match, but the first one matches a more specific entry in
U-Boot's device tree. The order in the kernel's device tree is ignored.

03e2ecf6b8 fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}
This makes the FAT and ext4 filesystem implementations build if
CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on
whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the
filesystems to be built separately from the filesystem-specific commands
that use them. This paves the way for the creation of filesystem-generic
commands that used the filesystems, without requiring the filesystem-
specific commands.

Minor documentation changes are made for this change.

The new config options are automatically selected by the old config
options to retain backwards-compatibility.

84cd93272e fs: Add a Coreboot Filesystem (CBFS) driver and commands
This change adds CBFS support and some commands to use it to u-boot. These
commands are:

cbfsinit - Initialize CBFS support and pull all metadata into RAM. The end of
the ROM is an optional parameter which defaults to the standard 0xffffffff and
can be used to support multiple CBFSes in a system. The last one set up with
cbfsinit is the one that will be used.

cbfsinfo - Print information from the CBFS header.

cbfsls - Print out the size, type, and name of all the files in the current
CBFS. Recognized types are translated into symbolic names.

cbfsload - Load a file from CBFS into memory. Like the similar command for fat
filesystems, you can optionally provide a maximum size.

Support for CBFS is compiled in when the CONFIG_CMD_CBFS option is specified.

The CBFS driver can also be used programmatically from within u-boot.

If u-boot needs something out of CBFS very early before the heap is
configured, it won't be able to use the normal CBFS support which caches some
information in memory it allocates from the heap. The
cbfs_file_find_uncached function searches a CBFS instance without touching
the heap.

constant strings in objects.   Otherwise all strings in common/ will be

Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a
quick enumberation of the PCI devices, but don't need any setup work done.
This is very beneficial on platforms that have u-boot loaded by another
boot loader which does a more sophisticated job of setup of PCI devices
than u-boot.  That way, u-boot can just read what's there and get on
with life.  This is what SeaBIOS does.

33eee330cc powerpc/fsl-corenet: work around erratum A004510
Erratum A004510 says that under certain load conditions, modified
cache lines can be discarded, causing data corruption.

To work around this, several CCSR and DCSR register updates need to be
made in a careful manner, so that there is no other transaction in
corenet when the update is made.

The update is made from a locked cacheline, with a delay before to flush
any previous activity, and a delay after to flush the CCSR/DCSR update.
We can't use a readback because that would be another corenet
transaction, which is not allowed.

We lock the subsequent cacheline to prevent it from being fetched while
we're executing the previous cacheline.  It is filled with nops so that a
branch doesn't cause us to fetch another cacheline.

Ordinarily we are running in a cache-inhibited mapping at this point, so
we temporarily change that.  We make it guarded so that we should never
see a speculative load, and we never do an explicit load.  Thus, only the
I-cache should ever fill from this mapping, and we flush/unlock it
afterward.  Thus we should avoid problems from any potential cache
aliasing between inhibited and non-inhibited mappings.

NOTE that if PAMU is used with this patch, it will need to use a
dedicated LAW as described in the erratum.  This is the responsibility
of the OS that sets up PAMU.
