This commit converts the brxre1 board to DM,
for this we have todo following things:- add a devicetree-file for this board
- drop all obsolete settings from board header-file
- use dm_i2c_xxx calls for read/write to the resetcontroller
- request gpios before operate themSerues-cc: trini@konsulko.com

- add a devicetree for each variant (mmc, spi, nand)
- drop unneeded code from board and bur/common
- drop unneeded stuff from config header files
- minor adaptions to be compliant with driver model (requesting gpio,..)
- harmonize the commandset over all brppt1 targetsSigned-off-by: Hannes Schmelzer
-
With this commit we do:
- set the bootdelay in all brppt1 defconfigs to 0, this makes
development easier, since we can break into serial console.- move CONFIG_BOOTCOMMAND from header file to defconfig
- introduce b_mode variable for selecting the final boot-target.
This b_mode represents the boot-switch, which can found on most b&r
targets. On the brppt1 this boot-switch is derived from some gpio and
the bootcounter within the RTC block, making it so possible to force
a boot-target (as example for repair-case).- refactor the environment for booting new flexible way
primary we want to get some bootscr.img within the mass-storage,
this script then loads everything needed for the boot.
For legacy reason we implement the t30lgcy#x boot targets, booting the
already delivered linux-images.- make space for the cfgscr within mtdparts on brppt1_nand

On other OS, not one provided by B&R, it is not guaranteed that there
are factory-settings within a devicetree. So we must not treat the
absence of them as error.
Further we've the fact that on different version of the device-tree
files there are different namings of the factory-settings, we consider
this with searching for an alternative name.changing things as following:
- don't treat as error if the bootloader version cannot written into
devicetree.- since the naming of the factory-settings are different in different
versions of the provided device-tree we search for the alternate name

If a board-code calls the pmicsetup(u32 mpupll) with a mpupll value
!= 0 it wants to force some frequency with the value provided by mpupll.
Setting up 1 GHz is wrong here.Nobody did take notice about that yet, since every board calls this
function with zero.Signed-off-by: Hannes Schmelzer

This interface names may vary over different products, to consider this

On this linux target long time ago the OS is using DRM driver for
handling video output, the pre initialization of u-boot and the display
summary screen is obsolete. With this patch we drop the LCD-support from
thisd board.Signed-off-by: Hannes Schmelzer
-
Since we're going to drop LCD-support on brppt1 boards, we have to make
this stuff here optional and remove the #error path.We also move out the ft_board_setup(...) from this #ifdef because
there's no relationship with the LCD-code and on the other hand this is
still needed in future even with LCD-support off.Signed-off-by: Hannes Schmelzer
-
The linux systems running on the brppt1 targets are using modern DRM
drivers since long time ago. Further we are going to drop the LCD
support completely on this board, so the simple-framebuffer setup
becomes obsolete.Signed-off-by: Hannes Schmelzer

This patch drops the lcd-screen setup, the summary screen and getting
mac-addresses based on a previous loaded device-tree for linux targets.
Selecting those linux target is simple, since we have only the brppt1.In detail we do:
- drop the common lcd-setup code which relys on a fdt_blob
- drop the common dtb loading mechanism
- drop the now obsolete CONFIG_USE_FDT from board header and whitelist.Signed-off-by: Hannes Schmelzer

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.Signed-off-by: Tom Rini

In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.This fixes failures such as:
board/ti/am335x/built-in.o: In function `board_late_init':
board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'which caters for use cases such as:
commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment

To keep a consistent MMC device mapping in SPL and in u-boot, let's
register the MMC controllers the same way in u-boot and in the SPL.
In terms of boot time, it doesn't hurt to register more controllers than
needed because the MMC device is initialized only prior being accessed for
the first time.
Having the same device mapping in SPL and u-boot allows us to use the
environment in SPL whatever the MMC boot device.Signed-off-by: Jean-Jacques Hiblot

Since we don't have for sure a valid IP-setup during
board_late_init(...) because it maybe allready stored in environment or
not, we cannot form a proper vxWorks bootline at this place.So we move to the way, forming the bootline just before
executing/launching vxWorks. To do this we use the bootvx command
instead go.We only have to form the "othbootargs" environment variable, the rest is
done pretty good by the "bootvx" commannd.Signed-off-by: Hannes Schmelzer

Since the used AM3352 SoC doesn't have GPU it isn't allways necessary to build
in complete drm-stuff into linux kernel. In very small applications only we use
the simple-framebuffer.So we have 2 use-cases:
- device operating on drm-driver (let simplefb node disabled)
- device operating on simplefb-driver (activate simplefb node and reserve mem)The decision is made by means of "simplefb" environment variable.
simplefb = 0
we don't enable the (maybe) existing simplefb node and all the rest around
display is up to the linux-kernel. We just disable the backlight, beceause we
do not want see the flicker during take over of drm-driver.simplefb = 1
