9f73690ceb autoboot.c: Fill env vars in process_fdt_options() only if TEXT_BASE is set
The x86 build target "efi-x86" has no TEXT_BASE configured. And with the
introduction of CONFIG_BOOTDELAY for x86, this function is now called
for this board as well. Resulting in compile errors for this target.

Without TEXT_BASE it makes no sense to fill these values. So lets only
configure the env variable if TEXT_BASE is defined.

4f144a4164 malloc: work around some memalign fragmentation issues
Use of memalign can trigger fragmentation issues such as:

// Internally, this needs to find a free block quite bit larger than s.
// Once the free region is found, any unaligned "padding" immediately
// before and after the block is marked free, so that the allocation
// takes only s bytes (plus malloc header overhead).
p = memalign(a, s);
// If there's little fragmentation so far, this allocation is likely
// located immediately after p.
p2 = malloc(x);
free(p);
// In theory, this should return the same value for p. However, the hole
// left by the free() call is only s in size (plus malloc header overhead)
// whereas memalign searches for a larger block in order to guarantee it
// can adjust the returned pointer to the alignment requirements. Hence,
// the pointer returned, if any, won't be p. If there's little or no space
// left after p2, this allocation will fail.
p = memalign(a, s);

In practice, this issue occurs when running the "dfu" command repeatedly
on NVIDIA Tegra boards, since DFU allocates a large 32M data buffer, and
then initializes the USB controller. If this is the first time USB has
been used in the U-Boot session, this causes a probe of the USB driver,
which causes various allocations, including a strdup() of a GPIO name
when requesting the VBUS GPIO. When DFU is torn down, the USB driver
is left probed, and hence its memory is left allocated. If "dfu" is
executed again, allocation of the 32M data buffer fails as described
above.

In practice, there is a memory hole exactly large enough to hold the 32M
data buffer than DFU needs. However, memalign() can't know that in a
general way. Given that, it's particularly annoying that the allocation
fails!

The issue is that memalign() tries to allocate something larger to
guarantee the ability to align the returned pointer. This patch modifies
memalign() so that if the "general case" over-sized allocation fails,
another allocation is attempted, of the exact size the user desired. If
that allocation just happens to be aligned in the way the user wants,
(and in the case described above, it will be, since the free memory
region is located where a previous identical allocation was located),
the pointer can be returned.

This patch is somewhat related to 806bd245b1 "dfu: don't keep
freeing/reallocating". That patch worked around the issue by removing
repeated free/memalign within a single execution of "dfu". However,
the same technique can't be applied across multiple invocations, since
there's no reason to keep the DFU buffer allocated while DFU isn't
running. This patch addresses the root-cause a bit more directly.

This problem highlights some of the disadvantages of dynamic allocation
and deferred probing of devices.

This patch isn't checkpatch-clean, since it conforms to the existing
coding style in dlmalloc.c, which is different to the rest of U-Boot.

e92029c0f4 env_mmc: support overriding mmc dev from board code
This enables boards to choose where to/from the environment should be
saved/loaded. They can then for example support using the same device
(dynamically) from which the bootloader was launched to load and save
env data and do not have to define CONFIG_SYS_MMC_ENV_DEV statically.

In my use case, the environment needs to be on the same device I
booted from. It can be the eMMC or an optional SD card.
I therefore would override mmc_get_env_dev in the board code, read the
CPU registers to determine where we booted from and return the
corresponding device index.

8d4f11c203 bootm: fix size arg of flush_cache() in bootm_load_os().
Variable _load_end_ points to end address of uncompressed buffer
(*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed

72a8cf8dcc Move all command code into its own directory
There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Unfortunately, with m68k I get this error:

873cc1d777 mmc: store hwpart in the block device
This will allow us to have multiple block device structs each referring
to the same eMMC device, yet different HW partitions.

For now, there is still a single block device per eMMC device. As before,
this block device always accesses whichever HW partition was most recently
selected. Clients wishing to make use of multiple block devices referring
to different HW partitions can simply take a copy of this block device
once it points at the correct HW partition, and use each one as they wish.
This feature will be used by the next patch.

In the future, perhaps get_device() could be enhanced to return a
dynamically allocated block device struct, to avoid the client needing to
copy it in order to maintain multiple block devices. However, this would
require all users to be updated to free those block device structs at some
point, which is rather a large change.

Most callers of mmc_switch_part() wish to permanently switch the default
MMC block device's HW partition. Enhance mmc_switch_part() so that it does
this. This removes the need for callers to do this. However,
common/env_mmc.c needs to save and restore the current HW partition. Make
it do this more explicitly.

Replace use of mmc_switch_part() with mmc_select_hwpart() in order to
remove duplicate code that skips the call if that HW partition is already
selected.

adc421e4ce arm: move gd handling outside of C code

more to assign gd from C code, as gd is mapped to r9,
and r9 may now be saved in the prolog sequence, and
restored in the epilog sequence, of any C functions.

Therefore arch_setup_gd(), which is supposed to set
r9, may actually have no effect, causing U-Boot to
use a bad address to access GD.

Fix this by never calling arch_setup_gd() for ARM,
and instead setting r9 in arch/arm/lib/crt0.S, to
the value returned by board_init_f_alloc_reserve().

Since 51209b1f42 ("Use common mtest iteration counting"),
do_mem_mtest has always reported 0 errors and hence returned 0, even
if errors were detected. Fix the helpers mem_test_alt() and
mem_test_quick() to return the number of errors found.

71105f50fe fdt: fix address cell count checking in fdt_translate_address()
Commit: dm: core: Enable optional use of fdt_translate_address()

Enables use of this function as default, but after this it's not
possible to get dev address for the case in which: '#size-cells == 0'

This causes errors when getting address for some GPIOs, for which
the '#size-cells' is set to 0.

Example error:
'__of_translate_address: Bad cell count for gpx0'

Allowing for that case by modifying the macro 'OF_CHECK_COUNTS',
(called from )__of_translate_address(), fixes the issue.

Now, this macro doesn't check, that '#size-cells' is greater than 0.

This is possible from the specification point of view, but I'm not sure
that it doesn't introduce a regression for other configs.

Please test and share the results.

Tested-on: Odroid U3, Odroid X2, Odroid XU3, Sandbox.

bc393a7954 fdt: Rewrite the logic in fdt_fixup_ethernet()
Currently in fdt_fixup_ethernet() the MAC address fix up is
handled in a loop of which the exit condition is to test the
"eth%daddr" env is not NULL. However this creates unnecessary
constrains that those "eth%daddr" env variables must be
sequential even if "ethernet%d" does not start from 0 in the
"/aliases" node. For example, with "/aliases" node below:

    aliases {
        ethernet3 = &enet3;
        ethernet4 = &enet4;
    };

"ethaddr", "eth1addr", "eth2addr" must exist in order to fix
up ethernet3's MAC address successfully.

Now we change the loop logic to iterate the properties in the
"/aliases" node. For each property, test if it is in a format
of "ethernet%d", then get its MAC address from corresponding
"eth%daddr" env and fix it up in the dtb.

In fdt_fixup_ethernet() only "usbethaddr" is handled to fix up the
first usb ethernet port MAC address. Other additional usb ethernet
ports are ignored as there is no logic to handle "usbeth%daddr".

It is suggested we should use "ethaddr" for all ethernet devices.
Hence deprecate "usbethaddr" usage in fdt_fixup_ethernet().

This is useful since it eliminates the remaining use of interrupt

where the same one routine is utilized for both EEPROM writing and

in both cases was set with 1 somehow.

That lead to a missing delay in case of writing which lead to write

cfdaf4caa2 part:efi: add bootable parameter in gpt command
The optional parameter bootable is added in gpt command to set the
partition attribute flag "Legacy BIOS bootable"

This flag is used in extlinux and so in with distro to select
the boot partition where is located the configuration file
(please check out doc/README.distro for details).

With this parameter, U-Boot can be used to create the boot partition
needed for device using distro.

example of use:

setenv partitions "name=u-boot,size=60MiB;name=boot,size=60Mib,bootable;\
                   name=rootfs,size=0"

> gpt write mmc 0 $partitions

> part list mmc 0

Partition Map for MMC device 0  --   Partition Type: EFI

Part	Start LBA	End LBA		Name
	Attributes
	Type GUID
	Partition GUID
  1	0x00000022	0x0001e021	"u-boot"

7d9cde1031 lib/tiny-printf.c: Add tiny printf function for space limited environments
This patch adds a small printf() version that supports all basic formats.
Its intented to be used in U-Boot SPL versions on platforms with very
limited internal RAM sizes.

To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This
will result in the SPL using this tiny function and the main U-Boot
still using the full-blown printf() function.

This code was copied from:
http://www.sparetimelabs.com/printfrevisited
With mostly only coding style related changes so that its checkpatch
clean.

The size reduction is about 2.5KiB. Here a comparison for the db-mv784mp-gp
(Marvell AXP) SPL:

Without this patch:
  58963   18536    1928   79427   13643 ./spl/u-boot-spl

With this patch:
  56542   18536    1956   77034   12cea ./spl/u-boot-spl

Note:
To make it possible to compile tiny-printf.c instead of vsprintf.c when
CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are
moved from common/console.c into vsprintf.c in this patch.

9854a8748c console: Add a console buffer
It is useful to be able to record console output and provide console input
via a buffer. This provides sandbox with the ability to run a command and
check its output. If the console is set to silent then no visible output
is generated.

This also provides a means to fix the problem where tests produce unwanted
output, such as errors or warnings. This can be confusing. We can instead
set the console to silent and record this output. It can be checked later
in the test if required.

It is possible that this may prove useful for non-test situations. For
example the console output may be suppressed for normal operations, but
recorded and stored for access by the OS. That feature is not implemented
at present.

66eef1e780 tools: zynqimage: Add Xilinx Zynq boot header generation to mkimage
As with other platforms vendors love to create their own boot header
formats. Xilinx is no different and for the Zynq platform/SoC there
exists the "boot.bin" which is read by the platforms bootrom. This
format is described to a useful extent within the Xilinx Zynq TRM.

This implementation adds support for the 'zynqimage' to mkimage. The
implementation only considers the most common boot header which is
un-encrypted and packed directly after the boot header itself (no
XIP, etc.). However this implementation does take into consideration the
other fields of the header for image dumping use cases (vector table and
register initialization).

a7c06cd3a6 env_ubi.c: Correct pointer error in env load
The variable "buf" in this function is a char array, and the
function ubi_volume_read is expecting a char *.  In the call, the
address of the pointer is being taken, incorrectly passing a
char **.  The compiler warning was being silenced by the cast.
Remove the address operator and the cast.

736d1746fb itest: add missing break statements to evalexp()
The commit mentioned below replaced return statements inside a switch so
that other code could be called after the switch. However, it didn't add
any break statements, causing the cases to run together. Fix this.

a1e56cf6d4 spl: mmc: add support for BOOT_DEVICE_MMC2
Currently the mmc device that SPL looks at is always mmc0, regardless
of the BOOT_DEVICE_MMCx value. This forces some boards to
implement hacks in order to boot from other mmc devices.

Make SPL take into account the correct mmc device.

f101e4bd37 spl: add support for alternative boot device
Introduce spl_boot_list array, which defines a list of boot devices
that SPL will try before hanging. By default this list will consist
of only spl_boot_device(), but board_boot_order() can be overridden
by board code to populate the array with custom values.

36afd45136 spl: change return values of spl_*_load_image()
Make spl_*_load_image() functions return a value instead of
hanging if a problem is encountered. This enables main spl code
to make the decision whether to hang or not, thus preparing
it to support alternative boot devices.

Some boot devices (namely nand and spi) do not hang on error.
Instead, they return normally and SPL proceeds to boot the
contents of the load address. This is considered a bug and
is rectified by hanging on error for these devices as well.
