90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

d714a75fd4 imx: replace CONFIG_SECURE_BOOT with CONFIG_IMX_HAB
CONFIG_SECURE_BOOT is too generic and forbids to use it for cross
architecture purposes. If Secure Boot is required for imx, this means to
enable and use the HAB processor in the soc.

1b51e5f4cd nitrogen6x: reserve used gpios
This prevents messages like
gpio@20a0000: get_value: error: gpio GPIO2_2 not reserved

when CONFIG_DM_GPIO is enabled.

Also, when CONFIG_DM_GPIO is enabled, checkboard is too
early to use gpio_get_value, so read it directly on failure.

4ab7ab0b8f imx: mx6qsabrelite: Update the SabreLite README
The information in the SabreLite README is inaccurate and sparse. The
upstream U-Boot can boot the SabreLite from SPI-NOR. Additionally, the
freely available imx_loader tool can be easily used to boot a board with a
corrupted SPI, the official Freescale/NXP manufacturing tools are not
required.

Reformat the document, adding a description of how to boot from SPI-NOR
and adding a brief description of how to recover the board should the
SPI-NOR be corrupted using imx_loader.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

155fa9af95 spi: mxc: fix sf probe when using mxc_spi
MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:

cs = (cs | gpio << 8)

This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".

This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.

Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.

461be2f96e kconfig: remove redundant "string" type in arch and board Kconfigs
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//
}
'

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

0a11d6f29c mx6: Remove duplication of iomuxc structure
There is no need to keep iomuxc_base_regs structure as it serves the exact same
purpose of the iomuxc structure, which is to provide access to the GPR
registers.

The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.

So remove iomuxc_base_regs structure and use iomuxc instead.
