This is regression of commit 2035d77d i2c: sh_i2c: Update to new CONFIG_SYS_I2C framework
Before commit 2035d77d, i2c probe command works properly on kzm9g board.

Valid chip addresses: 0C 12 1D 32 39 3D 40 60After commit 2035d77d, i2c probe command does not work.

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)

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.

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

Add yet another OCOTP driver for this i.MX family. This time, it's a driver for
the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too
different from the i.MX6 one that I could not use the mxc_ocotp.c driver without
making it into a big pile of #ifdef . This driver implements the regular fuse
command interface, but due to the IP blocks' limitation, we support only READ
and PROG functions.Signed-off-by: Marek Vasut

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.

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

Remove the in-structure ops and put them in mmc_ops with
a constant pointer to it.This makes the mmc structure smaller as well as conserving
code space (in theory).All in-tree drivers are converted as well; this is done in a

on nand flash using ubi, after the download of the new image into
the flash, the "rest" of the nand sectors get erased while flushing
the medium. With current u-boot version dfu-util may show:Starting download: [##################################################] finished!
state(7) = dfuMANIFEST, status(0) = No error condition is present
unable to read DFU statusas get_status is not answered while erasing sectors, if erasing
needs some time.So do the following changes to prevent this:
- introduce dfuManifest state
According to dfu specification
( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
"the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
of the status report by the host. Upon receipt of the anticipated
DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
completes its reprogramming operations."- when stepping into dfuManifest state, sending a PollTimeout
DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
(dfu-util) waits the PollTimeout before sending a get_status again.Signed-off-by: Heiko Schocher

Due to signed/unsigned comparison, '< sizeof(struct)' does not do the right
thing, since if ec_command() returns a -ve number we will consider this be
success.Adjust all comparisons to avoid this problem.
This error was found with sandbox, which gives a segfault in this case. On
ARM we may instead silently fail.We should also consider turning on -Wsign-compare to catch this sort of thing
in future.Reviewed-by: Andrew Chew
