Use get_device_and_partition() is better since:
1. It will call the device initialize function internally. So we can
remove the mmc intialization code to save many lines.
2. It is used by fatls/fatload/fatwrite. So saveenv & load env should
use it too.
3. It can parse the "D:P", "D", "D:", "D:auto" string to get correct
device and partition information by run-time.
Also we remove the FAT_ENV_DEVICE and FAT_ENV_PART. We use a string:
FAT_ENV_DEVICE_AND_PART.
For at91sam9m10g45ek, it is "0". That means use device 0 and if:
a)device 0 has no partition table, use the whole device as a FAT file
system.
b)device 0 has partittion table, use the partition #1.

When dfu_init_env_entities() fails part-way through, some entities may
have been added to dfu_list. These are only removed by dfu_free_entities().
If that function isn't called, those stale entities will still exist the

Commit 95fac6ab45 "sandbox: Use os functions to read host device tree"
removed the ability for get_device_and_partition() to handle the "host"
device type, and redirect accesses to it to the host filesystem. This
broke some unit tests that use this feature. So, revert that change. The
code added back by this patch is slightly different to pacify checkpatch.
However, we're then left with "host" being both:
- A pseudo device that accesses the hosts real filesystem.
- An emulated block device, which accesses "sectors" inside a file stored
on the host.
In order to resolve this discrepancy, rename the pseudo device from host
to hostfs, and adjust the unit-tests for this change.
The "help sb" output is modified to reflect this rename, and state where
the host and hostfs devices should be used.

When debugging drivers it is useful to see what I/O accesses were done
and in what order.
Even if the individual accesses are of little interest it can be useful to
verify that the access pattern is consistent each time an operation is
performed. In this case a checksum can be used to characterise the operation
of a driver. The checksum can be compared across different runs of the
operation to verify that the driver is working properly.
In particular, when performing major refactoring of the driver, where the
access pattern should not change, the checksum provides assurance that the
refactoring work has not broken the driver.
Add an I/O tracing feature and associated commands to provide this facility.
It works by sneaking into the io.h heder for an architecture and redirecting
I/O accesses through its tracing mechanism.
For now no commands are provided to examine the trace buffer. The format is
fairly simple, so 'md' is a reasonable substitute.
Note: The checksum feature is only useful for I/O regions where the contents
do not change outside of software control. Where this is not suitable you can
fall back to manually comparing the addresses. It might be useful to enhance
tracing to only checksum the accesses and not the data read/written.

- User plugs in an SD card
- Execute: mmc dev 1
- This still fails, since the HW isn't reprobed.
With this change, U-Boot behaves as follows:

Currently, "mmc dev 0" does not change the selected HW partition. I
think it makes more sense if "mmc dev 0" is an alias for "mmc dev 0 0",
i.e. that HW partition 0 (main data area) is always selected by default
if the user didn't request a specific partition. Otherwise, the following
happens, which feels wrong:
Select HW partition 1 (boot0):
mmc dev 0 1
Doesn't change the HW partition, so it's still 1 (boot0):
mmc dev 0
With this patch, the second command above re-selects the main data area.
Note that some MMC devices (i.e. SD cards) don't support HW partitions.
However, this patch still works, since mmc_start_init() sets the current
partition number to 0, and mmc_select_hwpart() succeeds if the requested
partition is already selected.

When a simple command like 'false' is provided, hush should return the

happily execute the empty string command immediate after 'false' and
then return a success code.
This behaviour does not seem very useful, and requiring the flag also
seems wrong, since it means that hush will execute only the first command
in a sequence.
Add a check for empty string and fall out of the loop in that case. That

However, these two operations must occur in series rather than in
parallel. First, the power supply ramps up to the level required to
power the USB device, and then the device may take a certain amount of
time to connect (assert D+/D- pullups).
Related, the maximum time that a device has to assert pullups is 1s not
100ms.

This patch contains an implementation of the fastboot protocol on the
device side and documentation. This is based on USB download gadget
infrastructure. The fastboot function implements the getvar, reboot,
download and reboot commands. What is missing is the flash handling i.e.
writting the image to media.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126798/ with the
following changes:
- Rebase to current mainline and updates for current gadget API
- Use SPDX identifiers for licenses
- Traced the history and added missing copyright to cmd_fastboot.c
- Use load_addr/load_size for transfer buffer
- Allow vendor strings to be optional
- Set vendor/product ID from config defines
- Allow Ctrl-C to exit fastboot mode
v4:
- Major re-write to use the USB download gadget. Consolidated function
code to a single file.
- Moved globals into single struct.
- Use puts and putc as appropriate.
- Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to
set the fastboot transfer buffer.
v5:
- Add CONFIG option documentation to README
- Rebase using new downloader registration

This patch adds support for the Android boot-image format. The header
file is from the Android project and got slightly alterted so the struct +
its defines are not generic but have something like a namespace. The
header file is from bootloader/legacy/include/boot/bootimg.h. The header
parsing has been written from scratch and I looked at
bootloader/legacy/usbloader/usbloader.c for some details.
The image contains the physical address (load address) of the kernel and
ramdisk. This address is considered only for the kernel image.
The "second image" defined in the image header is currently not
supported. I haven't found anything that is creating this.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126797/ with the
following changes:
- Rebased to current mainline
- Moved android image handling to separate functions in
common/image-android.c
- s/u8/char/ in header to fix string function warnings
- Use SPDX identifiers for licenses
- Cleaned-up file source information:
android_image.h is from file include/boot/bootimg.h in repository:
https://android.googlesource.com/platform/bootable/bootloader/legacy
The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a
usbloader.c would be from the same commit, but it does not appear
to have been used for any actual code.
v4:
- s/andriod/android/
- Use a separate flag ep_found to track if the entry point has been set
rather than using a magic value.

Former usb_cable_connected() patch broke compilation of boards which do
not support this feature.
I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added
its default implementation to gadget downloader driver code. There's
only one driver of this kind and it's unlikely there'll be another, so
there's no point in keeping it in /common.
Previously this function was declared in usb.h. I've moved it, since
it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended
for USB host implementation.
Existing code, confronted with default -EOPNOTSUPP return value,
continues as if the cable was connected.
CONFIG_USB_CABLE_CHECK was removed.

The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.
On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.
Typically the initialization got something like this in every driver.
struct mmc *mmc = malloc(sizeof(struct mmc));
memset(mmc, 0, sizeof(struct mmc);
/* fill in fields of mmc struct */
/* store private data pointer */
mmc_register(mmc);
By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:
struct mmc = mmc_create(&cfg, priv);
All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.
Changes since v1:
* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.

The following shell command fails:
if test -z "$x"; then echo "zero"; else echo "non-zero"; fi
(assuming $x does not exist, it prints "non-zero" rather than "zero").
... since "$x" expands to nothing, and the argument is completely
dropped, causing too few to be passed to -z, causing cmd_test() to
error out early.
This is because when variable expansions are processed by make_string(),
the expanded results are concatenated back into a new string. However,
no quoting is applied when doing so, so any empty variables simply don't
generate any parameter when the combined string is parsed again.
Fix this by explicitly replacing quoting any argument that was originally
quoted when re-generating a string from the already-parsed argument list.
This also fixes loss of whitespace in commands such as:
setenv space " "
setenv var " 1${space}${space} 2 "

$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

Unlike other commands (for example, "fatwrite"), ext4write would
interpret the "sizebytes" as decimal number. This is not only
inconsistend and unexpected to most users, it also breaks usage
like this:
tftp ${addr} ${name}
ext4write mmc 0:2 ${addr} ${filename} ${filesize}
Change this to use the standard notation of base 16 input format.

This is much like a regular shell's -e operator, except that it takes
multiple arguments to specify the device type and device/partition ID
in addition to the usual filename:
if test -e mmc 0:1 /boot/boot.scr; then echo yes; else echo no; fi

This emulates bash:
$ if test; then echo yes; else echo no; fi
no
Currently, the code sets expr = -1 in this case, which gets mapped to
0 (true) at the end of do_test() by the logical -> shell exit code
conversion.

Currently, ! can only be parsed as the first operator in an expression.
This prevents the following from working:
$ if test ! ! 1 -eq 1; then echo yes; else echo no; fi
yes
$ if test ! 1 -eq 2 -a ! 3 -eq 4; then echo yes; else echo no; fi
yes
Fix this by parsing ! like any other operator, and and handling it
similarly to -a and -o.

This better mirrors the behaviour of bash, for example:
$ if test -z = -z; then echo yes; else echo no; fi
yes
This is parsed as a string comparison of "-z" and "-z", since the check
for the binary "=" operator occurs first. Without this change, the
command would be parsed as a -z test of "-", followed by a syntax error;
a trailing -z without and operand.
This is a behavioural change, but I believe any commands affected were
previously invalid or bizarely formed.

do_test() currently uses strcmp() twice to determine which operator is
present; once to determine how many arguments the operator needs, then
a second time to actually decode the operator and implement it.
Rewrite the code so that a table lookup is used to translate the operator
string to an integer, and use a more efficient switch statement to decode
and execute the operator.
This approach also acts as enablement for the following patches.
This patch should introduce no behavioural change.

People who write (or scripts that auto-generate) extlinux.conf don't
want to know about HW-specific information such as FDT filenames. Create
a new extlinux.conf tag "fdtdir" that specifies only the directory where
FDT files are located, and defer all knowledge of the filename to U-Boot.
The algorithm implemented is:
==========
if $fdt_addr_r is set:
if "fdt" tag was specified in extlinux.conf:
load the FDT from the filename in the tag
else if "fdtdir" tag was specified in extlinux.conf:
if "fdtfile" is set in the environment:
load the FDT from filename in "$fdtfile"
else:
load the FDT from some automatically generated filename
if no FDT file was loaded, and $fdtaddr is set:
# This indicates an FDT packaged with firmware
use the FDT at $fdtaddr
==========
A small part of an example /boot/extlinux.conf might be:
==========
LABEL primary
LINUX zImage
FDTDIR ./
LABEL failsafe
LINUX bkp/zImage
FDTDIR bkp/
==========
... with /boot/tegra20-seaboard.dtb or /boot/bkp/tegra20-seaboard.dtb
being loaded by the sysboot/pxe code.

The specification for extlinux.conf[1] states that "fdt" is an alias for
"devicetree". To date, U-Boot only implements "fdt". Rectify that.

This is only required for "PIC" relocation and doesn't apply to modern
"PIE" relocation which does data relocation as well as code.
"init_sequence_r" is just an array that consists of compile-time
adresses of init functions. Since this is basically an array of integers
(pointers to "void" to be more precise) it won't be modified during
relocation - it will be just copied to new location as it is.
As a consequence on execution after relocation "initcall_run_list" will
be jumping to pre-relocation addresses. As long as we don't overwrite
pre-relocation memory area init calls are executed correctly. But still
it is dangerous because after relocation we don't expect initially used
memory to stay untouched.

The change to add 64bit initrd support broke 32bit initrd support as it
always set 64bits worth of data into the properties, even on 32bit
systems. The fix is to use addr_cell_len (which already says how much
data is in 'tmp') to set the property, rather than always setting 8.

For standalone images, bootm had a special case where the OS boot function
was NULL but did actually exist. It was just called manually.
This was removed by commit 35fc84fa which checks for the non-existence of
this function before the special case is examined.
There is no obvious reason why standalone is handled with a special case.
Adjust the code so that standalone has a normal OS boot function. We still
need a special case for when the function returns, but at least we can
avoid the main problem.
This is intended to fix the reported:
