Those commands basis on implementation of random UUID generator version 4
which is described in RFC4122. The same algorithm is used for generation
both ids but string representation is different as below.char: 0 9 14 19 24 36
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
UUID: be be be be be
GUID: le le le be beCommands usage:
- uuid []
- guid []The result is saved in environment as a "varname" variable if argument is given,
if not then it is printed.New config:

This patch adds support to generate UUID (Universally Unique Identifier)
in version 4 based on RFC4122, which is randomly.Source: https://www.ietf.org/rfc/rfc4122.txt
Changes:
- new configs:
- CONFIG_LIB_UUID for compile lib/uuid.c
- CONFIG_RANDOM_UUID for functions gen_rand_uuid() and gen_rand_uuid_str()
- add configs dependency to include/config_fallbacks.h for lib uuid.lib/uuid.c:
- add gen_rand_uuid() - this function writes 16 bytes len binary representation
of UUID v4 to the memory at given address.- add gen_rand_uuid_str() - this function writes 37 bytes len hexadecimal
ASCII string representation of UUID v4 to the memory at given address.Signed-off-by: Przemyslaw Marczak

[trini: Add CONFIG_EFI_PARTITION to fallbacks]
Signed-off-by: Tom Rini -
Changes in lib/uuid.c to:
- uuid_str_to_bin()
- uuid_bin_to_str()New parameter is added to specify input/output string format in listed functions
This change allows easy recognize which UUID type is or should be stored in given
string array. Binary data of UUID and GUID is always stored in big endian, only
string representations are different as follows.String byte: 0 36
String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
string UUID: be be be be be
string GUID: le le le be beThis patch also updates functions calls and declarations in a whole code.

This commit introduces cleanup for uuid library.
Changes:
- move uuidstring conversion functions into lib/uuid.c so they can be
used by code outside part_efi.c.
- rename uuid_string() to uuid_bin_to_str() for consistency with existing
uuid_str_to_bin()
- add an error return code to uuid_str_to_bin()
- update existing code to the new library functions.Signed-off-by: Przemyslaw Marczak

Commit 2faf5fb82ed6 introduced a regression that causes a data
abort when running scsi init followed by scsi reset.There are 2 problems with the original commit
1) ALLOC_CACHE_ALIGN_BUFFER() allocates memory on the stack but is
assigned to ataid[port] and used by other functions.
2) The function ata_scsiop_inquiry() tries to free memory which was
never allocated on the heap.Fix these problems by using tmpid as a temporary cache aligned buffer.
Allocate memory separately for ataid[port] and re-use it if required.Fixes: 2faf5fb82ed6 (ahci: Fix cache align error messages)

1. The Data timeout counter value in eSDHC_SYSCTL register is
not working as it should be, so add quirks to enable this
workaround to fix it to the max value 0xE.2. Add CONFIG_SYS_FSL_ERRATUM_ESDHC111 to enable its workaround.

The controller reset is performed now if command error occurs.
This commit adds the reset for the case of data related errors too.Signed-off-by: Andrew Gabbasov
Acked-by: Pantelis Antoniou -
Calculation of the timeout value should be based on actual clock value,
written to controller registers. Since mmc->tran_speed is either the
maximum allowed speed, or the preliminary value, that is be not yet
set to registers, the actual timeout, taken by the controller, based
on its clock settings, may be much longer than expected, based on
mmc->tran_speed value. In particular it happens at early initialization
stage, when typical value of mmc->tran_speed is 20MHz or 26MHz, while
actual clock setting, configured in the controller, is 400kHz.
It's more correct to use mmc->clock value for timeout calculation instead.Signed-off-by: Andrew Gabbasov

Prior to Kbuild, U-Boot could build under tools/ directory
withour configuring for a specific board.That feature was lost when switching to Kbuild.

Prior to Kbuild, the build system created a build directory,
when it did not exist, for out-of-tree build.This feature was dropped when we switched to Kbuild
because many of lines in makefiles were copied from Linux Kernel.
(In Linux Kernel, we have to create a build directory by ourselves
before starting build.)That feature seems worth reviving for less typing
even if our code and Linux Kernel diverge.Signed-off-by: Masahiro Yamada

This patch adds implementation of rand library based on hardware random
number generator of security subsystem in Exynos SOC.This library includes:
- srand() - used for seed hardware block
- rand() - returns random number
- rand_r() - the same as above with given seedwhich depends on CONFIG_EXYNOS_ACE_SHA and CONFIG_LIB_HW_RAND.

Since TIZEN group has been used 450 X 140 bmp logo for lunchbox,
this patch tries to change the logo size from 500 X 150 to official size.
By reducing image size, we also save about 35KB.To make row aligned 4 bytes, add 2 pixels to row. Therefore the real width
of image size is 452.Signed-off-by: Jonghwa Lee

U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.
Please check "TODO" in the comment blocks in
arch/{arm,nds32}/lib/asm-offsets.c.Signed-off-by: Masahiro Yamada

For some time we have been using the run_command() with properly crafted
string. Such approach turned to be unreliable and error prone.Switch to "native" mmc subsystem API would allow better type checking and
shall improve speed.Also, it seems that this API is changing less often than u-boot commands.
The approach similar to env operations on the eMMC has been reused.Signed-off-by: Lukasz Majewski

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.Signed-off-by: Pantelis Antoniou
