it should be.

For instance,

  $ make tricoder_config all

  ... modify include/configs/tricoder.h
  $ make

spl/u-boot-spl.lds should be updated in this case, but it wasn't.

To fix this problem, linker scripts generation should be handled
by $(call if_changed_dep,...) rather than by $(call if_changed,...).

reserved_0x000[4]), was missing some reserved field required for
alignment purpose (reserved_0x094[3] between pll4_denom and pll6_ctrl)
and further contained a too short reserved field causing further miss-

Discovered and tested by temporarily putting the following debug

1a9df13d5b arm: mxs: Add support for generating signed BootStream
This patch adds the groundwork for generating signed BootStream, which
can be used by the HAB library in i.MX28. We are adding a new target,
u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on
external _proprietary_ _binary-only_ tool from Freescale called 'cst',
which is available only under NDA.

To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

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       be

Commands usage:
- uuid [<varname>]
- guid [<varname>]

The result is saved in environment as a "varname" variable if argument is given,
if not then it is printed.

New config:
- CONFIG_CMD_UUID

4e4815feae lib: uuid: add functions to generate UUID version 4
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.

3f62971162 ahci: Fix data abort on multiple scsi resets.
Commit 2faf5fb82e 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: 2faf5fb82e (ahci: Fix cache align error messages)

00b132bf34 config:trats2: Change u-boot's TEXT_BASE from 0x78100000 to 0x43e00000
The u-boot's image TEXT_BASE needs to be changed to 0x43e00000 from 0x78100000.

This change provides compatibility with other trats2 (RD_PQ) devices
(http://download.tizen.org/releases/system/).

1336e2d343 mmc:eSDHC: Workaround for data timeout issue on Txxx SoC
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.

fb823981c5 mmc: fsl_esdhc: fix calculation of timeout for data transactions
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.

33ace362fd mmc: Add 'mmc rst-function' sub-command
Some eMMC chips may need the RST_n_FUNCTION bit set to a non-zero value
in order for warm reset of the system to work.  Details on this being
required will be part of the eMMC datasheet.  Also add using this
command to the dra7xx README.
